Real-time pollen data for Fort Worth — updated daily. Powered by board-certified allergists.
Fort Worth receives cedar pollen carried northward from the Hill Country on prevailing winds, particularly after cold fronts pass through. While Fort Worth is farther from the densest Ashe juniper forests than Austin or San Antonio, the lightweight pollen travels hundreds of miles. Cedar fever in Fort Worth is episodic — intense count days tied to weather fronts, followed by periods of lower exposure. Symptoms include severe congestion, fatigue, sore throat, and headache. Additionally, eastern red cedar (Juniperus virginiana) grows natively in the Fort Worth area and pollinates during the same winter window, adding a local cedar pollen source that Dallas and eastern DFW suburbs don't experience to the same degree.
Fort Worth's position in the heart of the Cross Timbers ecoregion — a historic band of oak and hickory woodland running through North Texas — makes spring tree pollen especially intense. Post oak is the signature tree of the Cross Timbers and produces heavy pollen loads. Live oak, red oak, elm, ash, pecan, hickory, cottonwood, poplar, mulberry, and maple trees all contribute from February through May. Pecan and hickory pollen are particularly potent allergens in the Fort Worth area, peaking in April. The Fort Worth Botanic Garden, Trinity Park, and the city's extensive mature tree neighborhoods in areas like Arlington Heights, Fairmount, and Southside add concentrated urban pollen sources.
Bermuda grass is the dominant grass allergen in Fort Worth, with Johnson grass, Timothy grass, Kentucky bluegrass, and ryegrass as additional contributors. Fort Worth's western location means more exposure to open prairie grasslands than the eastern side of the Metroplex. The city's ranching heritage and proximity to rural Tarrant County, Parker County, and the western prairies create grass pollen sources that extend beyond typical suburban lawns and parks. Grass pollen season runs roughly seven months from April through October.
The DFW area has among the highest ragweed counts and longest ragweed seasons in the United States, stretching up to four months from August through November. Fort Worth's western position, with more open land, vacant lots, and agricultural edges than urban Dallas, means additional weed pollen sources from pigweed, sagebrush, lamb's quarters, Russian thistle, and tumbleweed. Fall elm adds a second tree pollen wave from September through November, compounding ragweed exposure.
Mold thrives during Fort Worth's humid summers, with July and August producing the highest spore counts. Alternaria and Cladosporium are the dominant outdoor mold species. Fort Worth's older neighborhoods — including the historic Fairmount-Southside, Near Southside, and Northside districts — contain housing stock that can harbor mold and dust mite concentrations in older construction. Indoor allergens including dust mites, cockroach allergens, and pet dander are present year-round and intensify during winter and summer when homes are sealed.
Winter brings cedar fever as mountain cedar pollen travels north from the Hill Country after cold fronts. Fort Worth also has native eastern red cedar that adds a local winter pollen source. Cedar counts spike episodically with weather fronts rather than building gradually. Indoor allergens — dust mites, pet dander, cockroach allergens — intensify as residents seal homes and run heating systems. Elm trees may begin pollinating as early as late January during mild North Texas winters.
Top allergens: Mountain cedar, eastern red cedar, dust mites, indoor mold
Severity: Moderate to high (cedar), moderate (indoor)
Tip: Fort Worth gets cedar from two sources: Hill Country Ashe juniper carried on wind and local eastern red cedar. If your winter symptoms are more consistent than episodic, local cedar may be contributing. Track pollen counts after cold fronts pass — that's when Hill Country cedar peaks.
This is Fort Worth's most intense allergy period. The Cross Timbers ecoregion's post oak and hickory forests produce heavy pollen loads. Live oak, red oak, elm, ash, pecan, cottonwood, mulberry, and maple trees pile on. Pecan pollen peaks in April and is a potent North Texas allergen. By late April, grass pollen overlaps with tree pollen, creating a brutal double-exposure window. The Trinity River corridor and Fort Worth's extensive urban tree canopy concentrate pollen in the city.
Top allergens: Post oak, live oak, hickory, pecan, elm, ash, mulberry, early grass
Severity: High to very high
Tip: Fort Worth's Cross Timbers heritage means denser oak and hickory pollen than many other cities. Post oak pollen is a signature allergen here. Start medications by early March and keep car windows closed with AC on recirculate during the daily commute.
Bermuda grass peaks in early summer, with Johnson grass and ryegrass contributing. Fort Worth's summer heat and humidity create peak mold conditions, with July and August as the worst months for spore counts. Alternaria and Cladosporium thrive on dead vegetation and outdoor surfaces. Thunderstorms briefly wash pollen from the air but trigger mold surges within 24–48 hours. Fort Worth's western prairies and open ranch land contribute grass pollen that eastern DFW communities don't experience.
Top allergens: Bermuda grass, Johnson grass, mold spores (Alternaria, Cladosporium)
Severity: Moderate to high
Tip: Fort Worth's proximity to open prairie means grass pollen can arrive from the west on prevailing winds even if your immediate neighborhood is urban. If summer symptoms persist despite low local grass counts, regional sources may be the cause. Run dehumidifiers and replace AC filters monthly.
Ragweed season in Fort Worth stretches up to four months — among the longest in the country. Fort Worth's open western edges, vacant lots, and agricultural borders produce concentrated ragweed. Fall elm adds a second tree pollen wave overlapping with ragweed. Pigweed, sagebrush, tumbleweed, and Russian thistle contribute. Mold remains elevated from decomposing fall vegetation and leaves.
Top allergens: Ragweed (very high), fall elm, pigweed, sagebrush, mold
Severity: High to very high
Tip: Fort Worth's four-month ragweed season means OTC antihistamines face an endurance test. Start premedication by mid-August and consider sublingual immunotherapy targeting ragweed for lasting relief. Don't wait until September when symptoms peak.
Fort Worth sits squarely in the Cross Timbers ecoregion, a historic band of dense post oak and blackjack oak forest mixed with hickory that runs through North Texas. This is ecologically distinct from the blackland prairie to the east where Dallas sits. The advantage: Fort Worth's tree-lined neighborhoods are beautiful and provide shade. The disadvantage: this dense native canopy produces some of the heaviest oak and hickory pollen in the DFW Metroplex. If you live in Fort Worth's established neighborhoods like Arlington Heights, Fairmount, Ryan Place, or Berkeley Place, your immediate tree canopy is a significant pollen source during spring.
Unlike Dallas, which receives cedar pollen primarily from the Hill Country, Fort Worth has two cedar sources: the Ashe juniper pollen carried north from Central Texas on cold fronts and native eastern red cedar (Juniperus virginiana) growing locally in Tarrant County and the surrounding area. This can mean more consistent winter cedar exposure in Fort Worth compared to Dallas, where cedar arrives in distinct episodic waves. If your winter allergy symptoms are both episodic (after fronts) and persistent (on calm days), you may be reacting to both cedar types.
Fort Worth's western and southern edges transition into open prairie, ranch land, and rural Tarrant, Parker, and Johnson counties. These areas produce grass and weed pollen that blows into the city on prevailing westerly winds. Residents of west Fort Worth, Benbrook, Crowley, and the neighborhoods along the I-20 corridor may experience higher grass and ragweed exposure than those in central or northeast Fort Worth. During ragweed season (August–November), westerly and southwesterly winds carry concentrated weed pollen from these open areas directly into the city.
The DFW area has among the highest ragweed counts in the nation, and Fort Worth's proximity to open land extends that exposure. Ragweed season runs from August through November — up to four months. Starting medications in mid-August, before ragweed peaks in September, is far more effective than reactive treatment. If OTC antihistamines fail by October, sublingual immunotherapy targeting ragweed is the next step for lasting relief.
Fort Worth's spread-out geography — from the Stockyards in the north to the Cultural District in the west to Alliance in the far north — means daily commutes expose you to varied allergen environments. The Trinity River corridor running through the city creates a green corridor that channels pollen. I-30, I-35W, and Highway 121/183 commuters with windows down or ventilation on fresh air are getting concentrated pollen exposure. Keep AC on recirculate mode during spring and fall commutes.
With year-round allergies, Cross Timbers tree pollen, dual cedar sources, extended ragweed, and summer mold, managing Fort Worth allergies with OTC medications alone is a continuous struggle. HeyAllergy's board-certified allergists can identify your specific triggers through blood testing and create a personalized HeyPak® sublingual immunotherapy plan targeting North Texas allergens. Most patients notice improvement within 3–6 months. Book a telemedicine consultation from anywhere in Tarrant County — no clinic visit needed, no waitlist.
March through May (peak tree pollen from the Cross Timbers), September through November (ragweed — among the highest counts nationally), and December through February (cedar fever). Fort Worth has year-round allergies with no true off-season. Peak months are typically January (cedar), March–April (oak), and September–October (ragweed).
Fort Worth sits deeper in the Cross Timbers ecoregion, meaning heavier native oak and hickory pollen. Fort Worth also has native eastern red cedar in addition to Hill Country Ashe juniper pollen, creating dual cedar exposure. The western side of the Metroplex has more open prairie and ranch land, bringing additional grass and ragweed pollen from rural sources that eastern DFW doesn't experience.
Yes. Fort Worth receives mountain cedar (Ashe juniper) pollen from the Hill Country carried on prevailing winds after cold fronts. Additionally, eastern red cedar grows natively in the Fort Worth area and pollinates during the same winter window. This dual cedar exposure can make winter symptoms more persistent in Fort Worth than in some other DFW communities.

Fort Worth's allergy profile is shaped by its unique position at the ecological boundary where the Cross Timbers woodlands meet the Western Cross Timbers and the open Grand Prairie to the west. This is fundamentally different from Dallas's landscape just 30 miles east. The Cross Timbers — a historic band of dense post oak and blackjack oak forest mixed with hickory — defines Fort Worth's native tree canopy and produces some of the heaviest tree pollen in North Texas during spring. To the west and south, open prairie, ranch land, and agricultural areas in Parker, Johnson, and Hood counties generate grass and weed pollen that blows into the city on prevailing winds.
For Fort Worth's 960,000 residents, this dual-source allergen exposure — dense woodland pollen from the east and open-land grass and weed pollen from the west — creates a complex year-round allergy environment that differs meaningfully from other DFW communities.
The Cross Timbers ecoregion has shaped Fort Worth's landscape for centuries. Post oak, the signature species, thrives in the sandy, iron-rich soils of western Tarrant County and produces heavy spring pollen. Red oak, blackjack oak, live oak, hickory, pecan, elm, ash, and cottonwood trees add to the canopy. Fort Worth's established neighborhoods — Arlington Heights, Fairmount, Ryan Place, Berkeley Place, Mistletoe Heights, and the areas surrounding the Fort Worth Botanic Garden and Trinity Park — have mature trees that create beautiful, shaded streets and concentrated pollen corridors.
The Trinity River runs through the heart of Fort Worth and its forested banks create a continuous green corridor that channels pollen through the urban core. The river's riparian habitat supports cottonwood, elm, and willow trees that add to the spring pollen load. Fort Worth's investment in green infrastructure and urban forestry, while ecologically valuable, also means the city's tree pollen production capacity continues to grow.
Most DFW cities receive cedar pollen exclusively from the Hill Country, carried northward on post-cold-front winds. Fort Worth has an additional local source: eastern red cedar (Juniperus virginiana), which grows natively throughout Tarrant County and the surrounding area, particularly in less-developed western and southern areas. Eastern red cedar pollinates during the same December–February window as Ashe juniper, creating a dual cedar exposure that can make Fort Worth's winter allergy symptoms more persistent than in communities that only receive wind-carried Hill Country pollen.
This means Fort Worth residents may experience both episodic cedar spikes (after cold fronts carry Hill Country pollen) and lower-level persistent cedar exposure (from local eastern red cedar). For residents who notice winter allergy symptoms on calm days when Hill Country pollen transport is minimal, local cedar is likely the contributing factor.
Fort Worth's western orientation exposes it to prevailing westerly and southwesterly winds that cross open prairie, ranch land, and agricultural areas before reaching the city. During grass season (April–October), these winds carry Bermuda grass, Johnson grass, and other prairie grass pollen into Fort Worth from rural sources that extend well beyond the city limits. During ragweed season (August–November), the same wind patterns transport concentrated ragweed from the vast open lands to the west and south.
This prairie wind effect means Fort Worth's grass and weed pollen exposure includes not just urban and suburban sources but regional prairie contributions — a factor that distinguishes western DFW from the more sheltered eastern side of the Metroplex. Residents in west Fort Worth, Benbrook, White Settlement, and along the I-20 corridor are most exposed to these prairie-origin allergens.
Fort Worth's identity embraces its western heritage, from the Fort Worth Stockyards and rodeo culture to the Trinity River trails, the Fort Worth Botanic Garden, and the vibrant outdoor dining scene along Magnolia Avenue and West 7th Street. Major outdoor events — the Fort Worth Stock Show and Rodeo (January–February, coinciding with cedar season), Mayfest in Trinity Park (peak tree and early grass pollen), and the Panther Island events along the Trinity River — mean residents regularly participate in outdoor activities during high-allergen periods.
This outdoor culture makes allergy management not just a health concern but a quality-of-life priority. Being able to enjoy the Stockyards, bike the Trinity Trail, or dine on the Magnolia patio without allergy symptoms requires proactive treatment rather than reactive medication.
Fort Worth's geography spreads from Alliance and Haslet in the far north to Crowley and Burleson in the south, and from Benbrook in the west to the Arlington border in the east. Navigating I-35W, I-30, I-20, or Highway 121/183 for specialist appointments — especially during peak allergy season when demand surges — costs time that Fort Worth's working residents can't spare.
HeyAllergy eliminates these barriers. Residents from downtown Fort Worth to Keller to Southlake to Mansfield to Benbrook can see a board-certified allergist from home via secure video consultation. Blood allergy tests can be ordered to a convenient local lab anywhere in Tarrant County, and a personalized treatment plan — including HeyPak® sublingual immunotherapy drops targeting North Texas allergens — can begin without a single in-person visit. No needles, no I-35W traffic, no waitlist.
If the Cross Timbers oak pollen makes March through May unbearable, if cedar fever persists through calm winter days (suggesting local cedar exposure), if the four-month ragweed season from August through November is wearing you down, if OTC antihistamines aren't controlling your symptoms across Fort Worth's year-round allergy calendar, if summer mold makes July and August miserable, if you've recently moved to Fort Worth and developed new allergies, or if you have both allergies and asthma, it's time to see a board-certified allergist.
HeyAllergy accepts Medicare and most major PPO health plans, making expert allergy care accessible for residents throughout Tarrant County and the western DFW Metroplex.
