Real-time pollen data for Cape Coral — updated daily.
Cape Coral's subtropical climate means tree pollen season begins far earlier than most of the country — as early as mid-December when many northern states are buried in snow. Oak is the dominant tree allergen in Southwest Florida, with live oak and laurel oak producing massive pollen loads that coat cars, windows, and outdoor surfaces in visible yellow-green dust from February through April. Australian pine (Casuarina) — a highly allergenic invasive species that thrives in coastal Southwest Florida despite eradication efforts — pollinates in fall and again in spring, extending the tree pollen calendar in both directions. Bald cypress and juniper release pollen from December through February. Pine trees (slash pine, South Florida slash pine) contribute significant pollen from January through March. Melaleuca (paperbark tree), another invasive species present in the Cape Coral area, releases pollen nearly year-round though some research suggests its allergenic potency may be lower than other trees. Brazilian pepper (Schinus terebinthifolia) — an aggressive invasive that has colonized disturbed land, canal banks, and vacant lots throughout Cape Coral — blooms from September through November, producing airborne irritants that affect many residents. Palm trees including queen palm release low-level pollen year-round. The combination of native and invasive species means Cape Coral has no true tree-pollen-free period.
Grass pollen in Cape Coral operates on a nearly year-round calendar due to the subtropical climate, though peak levels occur during the warm, wet season from April through October. Bahia grass is the dominant grass allergen in Southwest Florida — it's extensively planted in lawns, parks, golf courses, and road medians throughout Cape Coral and Lee County, and produces highly allergenic pollen. Bermuda grass is also common in residential landscaping and athletic fields. St. Augustine grass is the most popular lawn grass in Cape Coral but releases relatively little airborne pollen; however, its thick turf harbors significant mold that becomes airborne during mowing. The warm, humid Gulf Coast climate means grasses grow continuously and can pollinate in every month of the year, with only brief reductions during the coolest weeks of January and February. Cape Coral's extensive development — the city is one of the largest in land area in Florida — means there are vast areas of maintained grass contributing to the local pollen load.
Ragweed is the most significant weed allergen in Cape Coral, pollinating from late August through November with peak intensity in September and October. Although ragweed counts in Southwest Florida are lower than in the Southeast and Midwest, the pollen's extreme potency means even moderate concentrations trigger symptoms in sensitized individuals. Ragweed pollen can travel hundreds of miles on wind, so pollen from more ragweed-dense regions of Florida and the Southeast contributes to local counts. Dog fennel is a common weed allergen in Southwest Florida's disturbed soils and vacant lots. Pigweed (amaranth), lamb's quarters, dock, nettle, and sorrel produce additional weed pollen from late summer through fall. Baccharis (groundsel bush) pollinates in fall along canal banks, wetland margins, and disturbed areas throughout Cape Coral. The extended warm season means some weed species continue producing pollen into December in Southwest Florida.
Indoor allergens are arguably the most clinically significant allergy challenge in Cape Coral. Southwest Florida allergists note that because outdoor pollen counts are actually lower than many other US regions, indoor allergen exposure is the primary driver of allergy symptoms for many local residents. Dust mites thrive in Cape Coral's perpetual warmth and humidity — the region's average relative humidity exceeds 70% year-round, creating ideal dust mite conditions in every home regardless of age or construction. Cape Coral's 400+ miles of canals — more canal waterway than any city on Earth — create a pervasive moisture environment that elevates humidity in homes citywide, particularly those with canal-front lots. Mold is ubiquitous in Southwest Florida, both outdoors and indoors. Outdoor mold spores (Alternaria, Cladosporium, Aspergillus) are present year-round and their counts have been correlated with emergency room visits for asthma in South Florida studies. Indoor mold grows in air conditioning systems, bathrooms, under sinks, and anywhere moisture accumulates. Pet dander and cockroach allergen are significant year-round contributors in Cape Coral homes.
Severity: Moderate to High
While the rest of the country is frozen, Cape Coral's allergy season is already active. Cypress and juniper pollen begins in December, joined by pine in January. By February, oak pollen begins its explosive release — the yellow-green coating on cars throughout Cape Coral from February through April is primarily oak pollen. Australian pine contributes additional tree pollen. This period coincides with Southwest Florida's dry season (November through May), and the drier conditions reduce mold levels somewhat while allowing pollen to remain airborne longer. Northeasterly trade winds during winter can carry pollen from inland agricultural and wooded areas toward the coast. Many seasonal residents (snowbirds) arrive during this period and experience what they assume are colds but are actually allergic reactions to unfamiliar subtropical allergens they don't encounter in their home states.
Severity: High to Severe
Late spring is Cape Coral's most intense multi-allergen period. Oak pollen persists into April while grass pollen (Bahia, Bermuda) rapidly escalates. The transition from dry season to wet season (typically beginning in June) brings increasing humidity that promotes mold growth while grasses thrive in the warm, increasingly wet conditions. Temperatures regularly reach the high 80s to low 90s°F. Mold spore counts begin climbing as afternoon thunderstorms become more frequent, wetting organic matter and promoting rapid mold proliferation. The combination of lingering tree pollen, rising grass pollen, and emerging mold creates the year's worst triple-allergen burden. Air conditioning systems running continuously can circulate indoor mold if not properly maintained.
Severity: Moderate to High
Cape Coral's wet season brings daily afternoon thunderstorms, tropical moisture, and the heart of hurricane season. Grass pollen remains elevated but the most significant allergen during this period is mold — outdoor mold spore counts peak during Southwest Florida's warm, wet months, and South Florida research has documented correlations between mold counts and emergency department asthma visits. The constant cycle of wetting and drying from afternoon storms creates ideal mold proliferation conditions. Cape Coral's 400+ miles of canals maintain standing water throughout the city, adding to the ambient moisture. Hurricane and tropical storm events can cause massive mold blooms in the aftermath as standing water, soaked building materials, and damaged structures create explosive mold growth. Ragweed begins pollinating in late August. Indoor humidity control becomes critical during this period.
Severity: Moderate
Fall brings ragweed peak (September–October), Brazilian pepper bloom (September–November), and Australian pine's fall pollen cycle. The transition from wet season to dry season (typically October–November) reduces but doesn't eliminate mold. October is often the wettest month in Cape Coral, meaning mold and weed pollen overlap significantly. As the dry season establishes, pollen counts from grasses and weeds decline but tree pollen from cypress and juniper begins again by December, starting the cycle anew. The brief November–December window between peak weed pollen and emerging tree pollen represents Cape Coral's closest approximation of an allergy reprieve, though indoor allergens persist and mold never fully abates.
Cape Coral is marketed as a "Waterfront Wonderland" with more than 400 miles of navigable canals — more canal waterway than any city on Earth, including Venice. While the canals are a major lifestyle attraction, they create a pervasive moisture microenvironment with significant implications for allergy sufferers. Homes on canal lots sit adjacent to standing water that elevates local humidity and provides a constant moisture source for mold growth. Even homes not directly on canals are affected because the canal network is so extensive that virtually every neighborhood is within blocks of open water. This means Cape Coral's ambient humidity is elevated compared to inland Southwest Florida communities. For allergy management: run air conditioning continuously (not just for cooling but for dehumidification), maintain indoor humidity below 50% using the AC and supplemental dehumidifiers if needed, clean AC drip pans and drainage regularly, and inspect for mold in any area where condensation accumulates.
Cape Coral contends with multiple invasive plant species that don't exist in most US cities but significantly affect local allergy sufferers. Australian pine (Casuarina) lines canal banks, roads, and vacant lots throughout the city and produces highly allergenic pollen in both fall and spring. Brazilian pepper has colonized disturbed land, empty lots, and canal margins extensively and produces airborne irritants during its September–November bloom that cause reactions in many residents. Melaleuca, though less prevalent in Cape Coral proper than in the Everglades region, is present in surrounding areas. These invasive species add allergens to the local environment that aren't present in most other US cities and aren't routinely tested for in standard allergy panels. If you're experiencing allergy symptoms in Cape Coral that don't correlate with standard pollen counts, invasive species exposure may be the explanation. A comprehensive allergy blood test through HeyAllergy can identify your specific triggers.
Cape Coral's large seasonal population — thousands of snowbirds arriving from northern states each winter — creates a common pattern allergists call the "relocation reaction." Newcomers from the Northeast and Midwest encounter subtropical allergens their immune systems have never experienced: Australian pine, Bahia grass, Brazilian pepper, subtropical mold species, and dust mite populations far larger than in their home states' drier or colder climates. Many seasonal residents assume their persistent congestion, sneezing, and itchy eyes during their Cape Coral stay represent a lingering cold or flu. In reality, they've developed allergic sensitization to Southwest Florida's unique allergen profile. If you're a seasonal resident who gets "sick" every time you arrive in Cape Coral, you likely need allergy testing, not antibiotics.
Cape Coral sits in one of Florida's most hurricane-vulnerable regions along the Gulf Coast. Beyond the immediate physical dangers, hurricanes and tropical storms create massive allergy and respiratory health events in their aftermath. Storm surge, flooding, and prolonged power outages (meaning no air conditioning or dehumidification) create conditions for explosive indoor mold growth that can persist for months or years if not properly remediated. Even homes that don't flood directly can experience elevated indoor humidity from prolonged AC outage and storm-driven moisture intrusion. Post-hurricane mold exposure has been documented to cause new-onset allergic sensitization in previously non-allergic individuals. If your Cape Coral home has experienced hurricane damage, professional mold assessment and remediation should be prioritized alongside structural repairs.
South Florida allergists emphasize that mold — not pollen — is likely the most clinically significant outdoor allergen in the region. Research from Miami Children's Hospital found that outdoor pollen counts in South Florida are surprisingly low compared to other US regions, but mold spore counts correlate directly with emergency department visits for asthma. In Cape Coral, the combination of year-round warmth, high humidity, extensive canal waterways, frequent rain during wet season, and subtropical vegetation creates ideal conditions for both outdoor and indoor mold proliferation. Addressing mold exposure — through HEPA air purifiers, dehumidification, AC maintenance, and eliminating indoor moisture sources — often provides greater symptom relief than pollen-focused interventions alone.

February through April is peak tree pollen season, with oak being the worst offender. April through June creates the most severe multi-allergen overlap as tree pollen, grass pollen, and mold all peak simultaneously during the dry-to-wet season transition. September through October brings peak ragweed and Brazilian pepper irritants. Mold is elevated year-round due to the canal system and Gulf Coast humidity.
The most common allergens are oak, Australian pine, Bahia grass, Bermuda grass, ragweed, mold (Alternaria, Cladosporium, Aspergillus), and dust mites. South Florida allergists report that mold and dust mites are likely more clinically significant than pollen in this region due to the pervasive humidity. Invasive species like Brazilian pepper and Australian pine add allergens unique to Southwest Florida.
Cape Coral's subtropical climate means year-round allergen exposure with no winter break. The 400+ mile canal system elevates ambient humidity, creating ideal conditions for dust mites and mold. Invasive subtropical species add allergens not found in northern states. Higher baseline humidity means indoor allergen levels are substantially elevated compared to drier or colder climates. Seasonal residents often develop new allergic sensitivities to unfamiliar subtropical allergens.

Yes. Cape Coral's subtropical climate supports year-round plant growth and pollination. Tree pollen peaks December through May, grass pollen peaks April through October, weed pollen peaks August through November, and mold and dust mites are elevated every month. There is no allergen-free season in Southwest Florida.
Yes. Cape Coral's 400+ miles of canals create a pervasive moisture environment that elevates humidity in homes citywide. This promotes dust mite proliferation and mold growth both outdoors and indoors. Canal-front homes are particularly affected. Dehumidification, continuous AC operation, and regular mold inspection are essential for canal-adjacent living.
Cape Coral — population approximately 210,000 and one of the fastest-growing cities in the United States — is famous for its 400+ miles of navigable canals, more than any city on Earth including Venice. This extensive canal network is the city's defining feature and primary real estate attraction, but it also creates one of the most challenging allergy environments in Florida. The canals maintain standing water throughout the city, elevating ambient humidity in every neighborhood and creating conditions where mold proliferates on canal banks, seawalls, vegetation, and in homes near the waterfront. Even residents who don't live directly on canals are affected because the network is so extensive that no neighborhood is more than a few blocks from open water. Combined with Southwest Florida's year-round warmth and Gulf Coast moisture, Cape Coral's canal system turns the entire city into a humidity amplifier where dust mites and mold — the two allergens most dependent on moisture — thrive at levels exceeding most other US cities.
Cape Coral's allergy landscape includes several invasive plant species that don't exist in most American cities but significantly affect local residents. Australian pine (Casuarina equisetifolia) is one of the most allergenic trees in Southwest Florida and has colonized canal banks, roadsides, vacant lots, and coastal areas throughout the region despite eradication efforts. It pollinates in both spring and fall, extending the tree allergy season in both directions. Brazilian pepper (Schinus terebinthifolia) is one of the most aggressive invasive plants in Florida and has spread extensively through Cape Coral's vacant lots, canal margins, and disturbed land. Its September through November bloom produces airborne compounds that trigger allergic reactions and respiratory irritation in many residents. Melaleuca (paperbark tree) is present in surrounding wetland areas. These invasive species add a layer of allergen complexity unique to the Southwest Florida region — residents relocating from other parts of the country encounter allergens their immune systems have never experienced, often leading to new-onset allergic sensitization.
Research from South Florida allergy specialists has documented a finding that surprises many residents: outdoor pollen counts in the region are actually significantly lower than in most other parts of the United States. But this doesn't mean allergies are less severe. The research found that mold spore counts — not pollen — correlated most strongly with emergency department visits for asthma in South Florida. Cape Coral's environment is essentially a mold incubator. Year-round temperatures above 60°F, average relative humidity exceeding 70%, the canal system maintaining ubiquitous surface water, seasonal afternoon thunderstorms during the six-month wet season, and dense subtropical vegetation provide ideal conditions for mold species including Alternaria, Cladosporium, Aspergillus, and Penicillium. Indoor mold is equally problematic — AC systems running continuously in Southwest Florida's heat and humidity can harbor mold in drip pans, ductwork, and air handlers if not maintained regularly. For many Cape Coral allergy sufferers, mold management provides more symptom relief than any pollen-focused intervention.
Cape Coral's substantial seasonal population creates a well-recognized clinical pattern. Thousands of snowbirds from the Northeast, Midwest, and Canada arrive each winter to escape cold weather, only to develop persistent congestion, sneezing, and respiratory symptoms they attribute to lingering colds or the flu. In reality, these seasonal residents are experiencing allergic sensitization to Southwest Florida's unique allergen profile — subtropical mold species, dust mite populations far larger than in their drier or colder home states, Australian pine, Bahia grass, and other allergens not present in their northern environments. The phenomenon often worsens over successive winters as the immune system's sensitization deepens with repeated exposure. Snowbirds who experience this pattern should pursue comprehensive allergy testing to identify their specific triggers rather than treating symptoms with repeated courses of cold medication or antibiotics that provide no benefit against allergic inflammation.
Cape Coral sits on Florida's Gulf Coast in one of the most hurricane-vulnerable regions in the United States. The city experienced devastating impacts from Hurricane Ian in September 2022, which brought catastrophic storm surge and flooding to many neighborhoods. Beyond the immediate physical damage, hurricanes and tropical storms create severe allergy and respiratory health crises in their aftermath. Flooding, prolonged power outages (meaning no air conditioning or dehumidification for days or weeks), and moisture intrusion into wall cavities and building materials create conditions for explosive mold growth that can persist for months or years if not properly remediated. Post-hurricane mold exposure has been documented to cause new-onset allergic sensitization and asthma in previously healthy individuals. If your Cape Coral home has experienced hurricane or flood damage, professional mold assessment should be prioritized alongside structural repairs to protect long-term respiratory health.
Cape Coral's combination of year-round allergens, canal-system humidity, invasive species, and hurricane-related mold events creates a complex allergy environment that benefits from specialist care. HeyAllergy provides telemedicine appointments with board-certified allergists and immunologists licensed in Florida, delivering expert allergy care directly to your Cape Coral home. A virtual consultation identifies your specific triggers through comprehensive allergy blood testing at a convenient local lab, then creates a personalized treatment plan addressing the exact combination of subtropical tree, grass, weed, mold, and dust mite allergens driving your symptoms. HeyPak sublingual immunotherapy drops ship directly to your door and build your immune system's tolerance over time — particularly valuable in a region where year-round allergen exposure means medications alone may never fully control symptoms. HeyAllergy accepts Medicare and most major PPO health plans. Starting at $47 per month, with most patients noticing improvement within 3 to 6 months.
