Real-time pollen data for Paradise — updated daily.
Paradise shares the Las Vegas Valley's distinctive tree pollen profile — one shaped more by landscaping history than native desert ecology. The most significant tree allergen is mulberry. In the 1960s, every new home purchase in the Las Vegas area included at least one fruitless mulberry tree for shade, and the species was massively overplanted across the valley. The resulting pollen was so severe that Clark County banned the planting and sale of mulberry trees in 1991. However, trees planted before the ban remain throughout Paradise's older neighborhoods and continue producing enormous quantities of highly allergenic pollen every spring. UNLV's Pollen Monitoring Program — the only NAB-certified station in Southern Nevada, located on UNLV's campus within Paradise — has documented mulberry as a 'chronic pollen offender' in the valley. Approximately 90 percent of the allergy-suffering population is allergic to mulberry pollen. European olive trees were banned in the same 1991 Clark County ordinance for identical reasons — extreme pollen production causing soaring allergy rates. Like mulberry, surviving pre-ban olive trees continue pollinating each spring. Ash trees release significant allergenic pollen in March and April. Oak pollen peaks from March through May, depositing visible yellow-green dust across the valley. Elm, pine, maple, cottonwood, and sycamore contribute additional spring tree pollen. Paradise's position at the center of the Las Vegas Valley — surrounded by older residential neighborhoods with mature pre-ban trees — means it receives tree pollen contributions from all directions.
Bermuda grass is the dominant lawn and landscape grass throughout Paradise and the Las Vegas Valley, producing substantial pollen from April through October. Despite the Mojave Desert setting, irrigated landscapes throughout Paradise — resort properties along the Strip, golf courses, UNLV's campus, residential yards, and parks — create extensive grass pollen sources within an otherwise arid environment. Bermuda grass pollen is fine, wind-dispersed, and produced in enormous quantities from these irrigated green spaces. Johnson grass grows along roadsides, highway medians, and disturbed soil. Ryegrass is used for winter overseeding of Bermuda grass lawns, extending grass pollen into cooler months. Kentucky bluegrass, timothy grass, fescue, salt grass, and orchard grass contribute additional pollen. The Las Vegas Valley's warm growing season supports grass pollen production for approximately seven months. The contrast between irrigated landscapes and surrounding desert is particularly stark in Paradise, where the Strip's lush resort landscaping exists immediately adjacent to arid terrain — creating concentrated pollen microenvironments within the broader desert setting.
Ragweed is the dominant fall weed allergen in the Las Vegas Valley and has reached extreme levels in recent years according to UNLV's pollen monitoring data. Ragweed pollen is lightweight and can travel hundreds of miles on wind, meaning Paradise receives contributions from both local plants and distant sources carried across the desert. Sagebrush is a native Mojave Desert shrub that produces copious lightweight pollen easily dispersed by wind — a significant fall allergen for valley residents. Russian thistle (tumbleweed) is iconic of the desert landscape; as plants dry and break free, they disperse seeds and pollen across wide areas. Pigweed (redroot amaranth), lamb's quarters (goosefoot), and English plantain contribute additional weed pollen. The extensive ongoing construction throughout Paradise — resort renovations, the Las Vegas Convention Center expansion, residential development, and infrastructure projects — creates continuous disturbed soil that pioneer weed species colonize rapidly. Vacant lots, of which Paradise has many in areas between the Strip corridor and residential neighborhoods, are documented major sources of both dust and weed pollen in Clark County.
Paradise encompasses Harry Reid International Airport (formerly McCarran), the nation's 5th busiest airport by passenger traffic, located at its southern end. Peer-reviewed research consistently documents elevated ultrafine particulate matter (UFP), PM2.5, black carbon, and polycyclic aromatic hydrocarbons near major airports. Ultrafine particles from jet engines are often sub-100 nanometers — small enough to cross into the bloodstream. For Paradise residents living near the airport or under flight paths, this represents a significant respiratory burden layered on biological allergens. The Las Vegas Metro Area ranks 10th nationally for worst ozone pollution. Clark County has never met federal attainment levels for ozone. Las Vegas received an 'F' grade for both daily PM2.5 and ozone levels. Mojave Desert dust is a defining non-biological respiratory challenge — windstorms can generate haboob-like dust events that reduce visibility and spike PM10 and PM2.5 across the valley. Clark County maintains a dedicated dust complaint hotline (702-385-DUST) because disturbed vacant land and construction sites are such major contributors to particulate pollution. Construction dust from the perpetual building and renovation cycle along the Strip corridor adds localized particulate exposure unique to Paradise. Indoor allergens including dust mites, cockroach allergen, mold (particularly in older resort and residential buildings with cooling systems), and pet dander are year-round concerns. Southern Nevada's dry climate actually worsens allergy symptoms by drying nasal passages, reducing the mucus that normally traps and filters allergens, allowing pollen and dust to penetrate deeper into the respiratory system.
Severity: Low to Moderate
Winter is Paradise's mildest allergy season, though not symptom-free. Average January highs around 58°F with occasional freezes, but the mild desert winter means some tree species can begin pollinating as early as February. Elm and early mulberry pollen may appear in late February during warm spells. Indoor allergens — dust mites, pet dander, mold in heating systems and older resort buildings — are primary triggers as residents spend more time indoors. Desert dust events can occur year-round when wind speeds increase. Harry Reid Airport operations continue uninterrupted, maintaining baseline UFP and PM2.5 levels for nearby residents. The relatively low pollen counts provide the best window for starting immunotherapy treatment before spring intensifies allergen exposure.
Severity: Severe
Spring is Paradise's worst allergy season by far. Mulberry pollen — from pre-ban trees still growing throughout the valley — explodes in March and April, producing some of the highest pollen concentrations measured by UNLV's monitoring stations. UNLV's campus, located within Paradise, serves as the valley's primary NAB-certified pollen monitoring site and has repeatedly documented mulberry as a chronic pollen offender. European olive tree pollen peaks in April and May from surviving pre-ban trees. Ash pollen surges in March and April. Oak pollen builds from March through May. Pine and cottonwood contribute additional tree pollen. By April, Bermuda grass begins producing pollen, compounding the tree pollen burden. Warm, dry, windy conditions — characteristic of Las Vegas spring — amplify pollen dispersal across the flat valley floor. The combination of banned-but-surviving tree pollen, emerging grass pollen, increasing ozone from rising temperatures, and construction dust from the perpetual Strip building cycle creates the most challenging respiratory period of the year.
Severity: Moderate to High
Summer brings extreme heat to Paradise — average July highs around 106°F with temperatures frequently exceeding 110°F. Bermuda grass pollen from irrigated landscapes peaks in June and remains elevated through August despite the heat. The defining respiratory challenge of Las Vegas summers is ground-level ozone. Extreme heat, intense sunlight, and vehicle emissions from the valley's heavy tourism traffic create ozone levels that have earned Las Vegas the 9th worst ozone ranking nationally. Ozone inflames airways already sensitized by spring pollen, explaining why symptoms persist even as tree pollen declines. Desert dust storms can occur when monsoon-season winds sweep across exposed desert terrain. Ragweed begins pollinating in late August. Indoor allergen exposure peaks as residents maximize air conditioning time. The extreme heat drives nearly all activity indoors, where recirculated air in resort properties, casinos, and residential buildings concentrates indoor allergens.
Severity: Moderate to High
Fall brings the Las Vegas Valley's worst weed pollen season. Ragweed peaks from September through October, reaching extreme levels in recent years according to UNLV monitoring data. Sagebrush — the native Mojave Desert shrub — releases copious lightweight pollen carried by wind across the valley, significantly impacting Paradise residents. Russian thistle (tumbleweed) disperses as dried plants tumble across the landscape. Pigweed, lamb's quarters, and English plantain add overlapping fall weed pollen. Bermuda grass continues producing some pollen into October. Mold spores can increase following fall rains, particularly around irrigated landscapes and older buildings. Ozone levels gradually moderate from summer peaks as temperatures decline. By November, weed pollen tapers as temperatures drop toward winter lows. The transition between fall weed decline and the start of the next tree pollen cycle in February provides a relatively brief window of lower pollen counts through December and January.
Many people relocate to the Las Vegas area expecting desert air to provide allergy relief. The reality is the opposite for most. Southern Nevada's extremely low humidity dries nasal passages and reduces the mucus your body produces to trap and filter allergens. This means pollen and dust particles penetrate deeper into your respiratory system than they would in a humid climate. Research from UNLV confirms that the dry climate makes allergies worse by disabling one of the body's primary natural defenses. Additionally, most of Paradise's worst allergens are not native desert plants but non-native species planted for landscaping — mulberry, olive, Bermuda grass — that were introduced to make the desert livable and now produce enormous quantities of pollen in an environment where those natural filtration defenses are compromised. Use saline nasal rinses daily to maintain moisture in nasal passages. Run a humidifier in your bedroom. Stay hydrated — the dry air accelerates fluid loss that affects your respiratory defenses.
Clark County banned the planting and sale of mulberry and European olive trees in 1991 because both species produce extraordinary amounts of highly allergenic pollen. In the 1960s, every new home purchase in the Las Vegas area included at least one mulberry tree for shade, and the species was massively overplanted. According to UNLV researchers, approximately 90 percent of the allergy-suffering population is allergic to mulberry pollen. Despite the ban, trees planted before 1991 remain throughout Paradise's older neighborhoods, and as these mature trees grow larger, they actually produce more pollen each year. UNLV's Pollen Monitoring Program — certified by the National Allergy Bureau and located on campus within Paradise — has documented mulberry as a 'chronic pollen offender' in the valley. European olive trees face the same situation. If you live near mature mulberry or olive trees, HEPA air purifiers in bedrooms are essential during March through May. Begin antihistamines or nasal corticosteroid sprays in late February before peak pollen arrives.
Harry Reid International Airport — the nation's 5th busiest by passenger traffic — sits within Paradise's boundaries at the community's southern end. Peer-reviewed systematic reviews document that the near-airport environment is a hotspot for ultrafine particulate matter (UFP), PM2.5, black carbon, and polycyclic aromatic hydrocarbons. Ultrafine particles from jet engines are smaller than those from ground transportation (often sub-100 nanometers), penetrating deep into the lungs and potentially crossing into the bloodstream. For Paradise residents living south of the Strip corridor, near the airport, or under primary flight paths, airport emissions add a layer of respiratory irritation that compounds biological allergen effects. Run HEPA air purifiers in bedrooms if you live near the airport or under flight paths. Monitor air quality at airnow.gov or the Clark County DES air quality monitoring website. Limit outdoor exercise during peak airport traffic hours if you live in southern Paradise.
Paradise encompasses the Las Vegas Strip — a corridor in perpetual construction, renovation, and demolition. Every major resort project displaces massive amounts of desert soil and construction material, releasing both mineral dust and biological allergens trapped in the soil. Clark County's Department of Environment and Sustainability maintains a dedicated dust complaint hotline (702-385-DUST) specifically because construction sites and disturbed vacant lots are such significant contributors to particulate pollution in the valley. Vacant lots between the Strip corridor and residential neighborhoods — common in Paradise's transitional zones — are documented major dust sources. Desert dust events from the surrounding Mojave can generate haboob-like conditions that spike PM10 and PM2.5 across the valley. When combined with airport emissions, ozone pollution (Las Vegas ranks 9th worst nationally for ozone), and biological pollen, Paradise residents face a multi-layered respiratory challenge that makes managing allergies more complex than pollen alone would suggest.
Paradise is home to UNLV's Pollen Monitoring Program — the only National Allergy Bureau-certified pollen station in Southern Nevada. Established in 2013 as a partnership between UNLV, Clark County School District, and the county Department of Air Quality, the program operates the certified station on UNLV's campus (within Paradise) plus four additional sites at schools across the valley. This provides neighborhood-level pollen data that valley-wide averages miss. Check daily pollen counts from the UNLV station through the NAB website or local weather reports. Research published by the program has documented that mulberry remains a chronic offender, ragweed has reached extreme levels, and pollen concentrations vary significantly by neighborhood based on proximity to surviving pre-ban trees and irrigated landscapes.

March through May is the worst period, when mulberry, olive, ash, and oak pollen from pre-ban trees peaks alongside emerging Bermuda grass. September through October brings intense ragweed and sagebrush weed pollen. Summer adds extreme ozone pollution that amplifies allergic responses. December through February offers the most relief, though indoor allergens persist year-round.
The most common allergens in the Las Vegas Valley are mulberry tree pollen (despite the 1991 ban), European olive pollen, ash, oak, Bermuda grass, ragweed, sagebrush, Russian thistle, desert dust, dust mites, cockroach allergen, and mold. Most of the worst tree allergens are non-native species planted for landscaping, not native desert plants. A blood allergy test identifies your specific triggers.
Clark County banned the planting and sale of mulberry and European olive trees in 1991 because both species produce extraordinary amounts of highly allergenic pollen. In the 1960s, mulberry trees were included with every new home purchase for shade and were massively overplanted. The resulting pollen caused severe allergic reactions across the valley. Trees planted before the ban still exist and continue pollinating — growing larger and producing more pollen each year.

Many people relocate to the desert expecting allergy relief, but the opposite often occurs. Southern Nevada's extremely low humidity dries nasal passages and reduces the mucus that normally traps allergens, allowing pollen and dust to penetrate deeper into your respiratory system. Additionally, most of Paradise's worst allergens — mulberry, olive, Bermuda grass — are non-native species that produce enormous pollen in an environment where your natural defenses are compromised. This is compounded by airport emissions, construction dust, and ozone pollution.
Paradise, Nevada — population approximately 255,000 — is the unincorporated community that most visitors and many residents think of as 'Las Vegas.' The Las Vegas Strip, Harry Reid International Airport (the nation's 5th busiest), UNLV, the Las Vegas Convention Center, and most of the iconic resorts and entertainment venues are actually located in Paradise, not within Las Vegas city limits. This geographic reality matters for allergy sufferers because Paradise sits at the epicenter of the Las Vegas Valley's most concentrated sources of both biological allergens and non-biological respiratory irritants: airport ultrafine particle emissions from 50+ million annual passengers, perpetual construction and renovation dust from the Strip corridor, ozone pollution from the valley's intense vehicle traffic serving 45+ million annual tourists, Mojave Desert dust from surrounding arid terrain, and the pollen legacy of non-native trees planted decades ago that Clark County was forced to ban in 1991.
The most significant allergen story in Paradise — and the broader Las Vegas Valley — is one of unintended consequences. When Southern Nevada was developing rapidly in the 1960s, every new home purchase included at least one fruitless mulberry tree for shade. The species was drought-resistant and fast-growing, perfect for desert landscaping. Mulberry trees were planted by the tens of thousands across the valley. The problem became apparent as these trees matured and began producing extraordinary quantities of allergenic pollen. According to UNLV researchers, approximately 90 percent of the allergy-suffering population is allergic to mulberry pollen. European olive trees, also planted extensively for their Mediterranean aesthetic and drought tolerance, created similar problems. By 1991, allergy rates had soared to such unprecedented levels that Clark County took the unusual step of banning the planting and sale of both mulberry and European olive trees — one of very few allergen-motivated tree bans in American history. The ban stopped new plantings but did nothing about existing trees. Decades later, pre-ban mulberry and olive trees remain throughout Paradise's older neighborhoods, and as these mature trees grow larger, they actually produce more pollen each year. UNLV's Pollen Monitoring Program, established in 2013 and operating its certified station on campus within Paradise, has published research documenting mulberry as a 'chronic pollen offender' in the valley. Pollen concentrations vary significantly by neighborhood based on proximity to surviving pre-ban trees — meaning two Paradise residents living a mile apart can experience dramatically different spring pollen exposure.
Harry Reid International Airport occupies a large footprint at Paradise's southern end, handling approximately 50 million passengers annually — making it the 5th busiest airport in the United States. The respiratory health implications of living near a major airport are well-documented in peer-reviewed research. A systematic review in Environmental Research: Infrastructure and Sustainability found that the near-airport environment is consistently a hotspot for ultrafine particulate matter (UFP), PM2.5, black carbon, and polycyclic aromatic hydrocarbons (PAHs). Ultrafine particles from jet engine emissions are smaller than those from typical ground transportation — often sub-100 nanometers in diameter — allowing them to penetrate deep into the lungs and potentially cross into the bloodstream. Studies at Los Angeles International Airport documented UFP counts of 50,000 particles per cubic centimeter at 500 meters downwind, compared to background levels of 580 to 3,800. For Paradise residents — particularly those living south of the Strip corridor, near the airport, or under primary flight paths — airport-related particulate exposure represents a respiratory burden layered on top of biological allergens. The EDF (Environmental Defense Fund) has identified airport ultrafine particle emissions as 'a longstanding and deadly environmental injustice' for near-airport communities.
The common assumption that desert climates provide allergy relief is one of the most persistent myths in allergy medicine — and Paradise is a case study in why it fails. Southern Nevada's extremely low humidity dries out nasal passages and reduces the mucus your body produces to trap and filter airborne allergens. UNLV researchers have confirmed that this dry climate actually makes allergies worse by compromising one of the body's primary natural defenses against pollen and dust. Allergens that would be partially trapped by moist nasal passages in humid climates penetrate deeper into the respiratory system in the dry desert air. Additionally, most of Paradise's worst allergens are not native desert plants but non-native species imported for landscaping — mulberry, European olive, Bermuda grass — that have been irrigated into prolific pollen production within an environment that strips away natural respiratory defenses. This explains why people who relocate to the Las Vegas area for allergy relief often find their symptoms unchanged or worse. The Asthma and Allergy Foundation of America has rated Las Vegas as the 31st worst metropolitan area for allergy sufferers — far from the allergy haven many newcomers expect.
Paradise faces a convergence of non-biological respiratory irritants that compound biological allergen effects. The Las Vegas Strip — running through Paradise's center — exists in a state of perpetual construction, renovation, and demolition. Every major resort project displaces massive amounts of desert soil, releasing mineral dust and biologically active particles into the air. Clark County maintains a dedicated dust complaint hotline (702-385-DUST) specifically because construction sites and disturbed vacant lots are such significant contributors to particulate pollution. The Las Vegas Metro Area ranks 9th nationally for worst ozone pollution, and Clark County has never met federal attainment levels for ozone. Las Vegas received an 'F' grade for both daily PM2.5 and ozone levels. Research shows that urban pollution does not simply add to allergy discomfort — it fundamentally changes how the body responds to pollen, damaging pollen grain surfaces and stimulating stronger immune responses that amplify allergic reactions. Mojave Desert windstorms can generate haboob-like dust events that spike particulate matter across the valley. For allergy sufferers in Paradise, the result is a multi-layered respiratory environment where biological pollen, airport emissions, construction dust, ozone, and desert particulates interact to produce symptoms more severe than any single factor alone.
