Real-time pollen data for West Palm Beach — updated daily.
Oak is West Palm Beach's dominant tree allergen, with live oak beginning to pollinate as early as January — a full two months before northern states see any tree pollen. Pine (slash pine), cypress, and elm add to the winter-spring pollen load. Australian pine (Casuarina), an invasive species established along the Lake Worth Lagoon shoreline and canal levees, produces significant allergenic pollen during winter months when residents expect relief. Brazilian pepper (Schinus terebinthifolius), a cashew-family invasive found throughout Palm Beach County's disturbed areas and canal corridors, blooms September through November with both airborne pollen and volatile oils that cause respiratory irritation and contact dermatitis. Melaleuca (paperbark tree), another Everglades invasive, adds additional pollen. Palm, maple, bayberry, and ash species contribute at various points.
Bahia grass is the most common lawn grass in Palm Beach County and a major allergen from April through October. Bermuda grass and St. Augustine grass are also widely planted in residential lawns, parks, and golf courses — of which West Palm Beach and Palm Beach County have an extraordinary number. The grass pollen season is exceptionally long due to the subtropical climate, with some species producing pollen nearly year-round. Wild grasses along canal levees and undeveloped lots add to the regional burden.
Ragweed is a significant fall allergen in West Palm Beach, but its impact is amplified by an unusual dynamic: because ragweed isn't as continuously present as other local allergens, residents' immune systems don't build tolerance. When ragweed spikes, the body overreacts, producing more severe symptoms than the pollen count alone would suggest. Lamb's quarters, dock, nettle, marsh elder, and saltbush contribute additional weed pollen, with saltbush and marsh elder particularly prevalent in coastal and lagoon-adjacent areas. Spanish needle and dog fennel are common roadside weeds throughout Palm Beach County.
Mold is one of West Palm Beach's most significant allergens. The C-51 Canal and two other major drainage canals, Lake Worth Lagoon's brackish estuary, the Grassy Waters Preserve wetland, and persistent humidity exceeding 70% create ideal conditions for year-round mold growth. Alternaria, Cladosporium, Aspergillus, and Penicillium grow continuously in HVAC systems, bathrooms, and anywhere moisture accumulates. The wet season (June–October) brings dramatic mold spikes as rainfall saturates the low-lying landscape. Screened-in lanais and pool enclosures — standard in South Florida homes — trap humidity and become mold habitat.
Dust mites thrive continuously in West Palm Beach's humidity, which rarely drops below 60% indoors even with air conditioning. Pet dander and cockroach allergens are significant perennial triggers throughout Palm Beach County's residential settings. Homes in historic neighborhoods built during the 1920s–1940s land boom era (El Cid, Flamingo Park, Northwood) may have construction particularly vulnerable to moisture intrusion and indoor mold.
Severity: Moderate to High. Oak trees begin pollinating in January — South Florida's pollen counts stay elevated longer than even Central Florida. Cypress, elm, and Australian pine along the lagoon and canal levees add winter pollen. Mold remains elevated from the canal system, lagoon, and Grassy Waters Preserve. While northern states enjoy complete allergy breaks, West Palm Beach residents enter tree pollen season with no pause from fall allergens.
Severity: Severe. This is West Palm Beach's worst pollen period. Oak pollen reaches its annual peak, coating cars, patios, and outdoor furniture in visible yellow-green dust. Pine pollen adds to the load. Grass pollen begins ramping up in April. Spring thunderstorms trigger mold spore surges from the canal system and lagoon-adjacent areas. The combination of peak tree pollen plus emerging grass pollen makes this the most challenging period for multi-sensitized individuals.
Severity: High. Bahia and Bermuda grass pollen peaks as temperatures climb into the 90s. The wet season begins, bringing afternoon thunderstorms that saturate the low-lying landscape and trigger explosive mold growth along canal corridors and in the lagoon's estuary margins. Humidity rises above 70%, overwhelming air conditioning systems and feeding indoor dust mites and mold.
Severity: High (mold and indoor allergens). Summer heat and humidity reach their peak. Tropical moisture and frequent thunderstorms keep mold spore counts elevated across the entire canal and lagoon system. Ragweed begins in mid-August. Hurricane threats can cause flooding and moisture intrusion that triggers acute mold events in homes. The C-51 Canal and other drainage channels surge with freshwater carrying organic matter from as far west as Lake Okeechobee.
Severity: High. Ragweed peaks, producing the immune "overreaction" effect due to intermittent exposure. Brazilian pepper blooms along canal levees and throughout disturbed areas, releasing both pollen and irritating volatile oils. Mold remains elevated from wet season moisture. This triple-allergen period offers no break from the summer mold peak. Grass pollen continues into October.
Severity: Low to Moderate. The closest West Palm Beach comes to an allergy break. Ragweed and Brazilian pepper fade. But oak pollen begins its early cycle, Australian pine starts winter pollination along the lagoon, and mold never fully subsides. Indoor allergens remain elevated as some homes are closed up for the brief cooler period. The "break" is measured in weeks, not months.
Ragweed isn't as continuously present in West Palm Beach as other allergens like oak or grass. This means your immune system doesn't build tolerance to it. When ragweed does spike in late summer and fall, your body overreacts to an allergen it hasn't been fighting daily — producing more severe symptoms than you'd expect. If ragweed episodes hit you harder than your everyday allergies, this is likely why. An allergist can confirm ragweed sensitivity and include it in an immunotherapy treatment plan.
The C-51 Canal (West Palm Beach Canal) drains over 350,000 acres of land from Lake Okeechobee through the city to Lake Worth Lagoon. The canal and its levees are colonized by Australian pine, Brazilian pepper, and exotic grasses that produce allergenic pollen. During rainy season (June–October), freshwater surges through the canal system carry organic matter and promote mold growth along the entire corridor. If you live near any canal in West Palm Beach, expect elevated mold and invasive-species pollen exposure.
Many West Palm Beach residents believe the Atlantic breeze provides allergy relief. In reality, onshore winds carry moisture from Lake Worth Lagoon inland, increasing humidity and mold spore transport. The lagoon's brackish water, remaining mangrove stands, and restored salt marsh grasses all produce mold. Sea breeze cycles can actually push lagoon-origin allergens deeper into residential neighborhoods during afternoon hours.
Screened-in outdoor spaces are standard in Palm Beach County homes. These semi-enclosed areas trap humidity and create surfaces where mold colonizes — on furniture, screening material, and concrete. Pool enclosures add chlorinated moisture to the mix. Clean these spaces regularly with mold-inhibiting solutions and don't assume they're allergen-free zones.
West Palm Beach's outdoor lifestyle revolves around waterfront locations — Clematis Street District, the Waterway, Currie Park, SunFest, and the Norton Museum grounds. These venues are adjacent to Lake Worth Lagoon, maximizing exposure to lagoon-origin mold spores and the allergens produced by restored mangrove and salt marsh habitats. Check the pollen forecast and pre-medicate before spending extended time at any waterfront venue, especially during spring tree pollen and fall ragweed seasons.
West Palm Beach's humidity regularly exceeds 70% outdoors, and standard air conditioning may not reduce indoor levels below the 50% threshold needed to control dust mites and mold. Run a whole-home or portable dehumidifier, especially during the June–October wet season. Homes in older neighborhoods like El Cid, Flamingo Park, and Northwood — built during the 1920s–1940s land boom era — may have construction that's particularly vulnerable to moisture intrusion.
February through April is typically the worst for tree pollen, when oak and pine peak. June through September combines grass pollen, ragweed onset, peak mold from wet season rainfall, and hurricane season humidity. However, West Palm Beach has no true allergy-free season — even in winter, oak and Australian pine pollen are present and mold remains elevated.
Effectively yes. Tree pollen starts in January, grass pollen runs April through October, ragweed extends August through December, Brazilian pepper blooms September through November, and mold is elevated year-round. Dust mites thrive continuously in the high humidity. South Florida's pollen counts stay elevated longer than even Central Florida.
Onshore winds from the Atlantic carry moisture from Lake Worth Lagoon — a 20-mile brackish estuary — inland across West Palm Beach. The lagoon's mangrove stands, salt marsh restorations, and decomposing organic matter produce mold spores that the sea breeze pushes into residential neighborhoods. The breeze also carries elevated humidity that feeds indoor mold and dust mites.

Brazilian pepper (Schinus terebinthifolius) is an aggressive invasive tree found throughout Palm Beach County's canal levees, disturbed areas, and natural lands. It's in the cashew family and produces both airborne allergenic pollen and volatile oils that cause contact dermatitis and respiratory irritation. It blooms September through November. Many residents don't realize this common landscape tree is an allergen source.
Yes. Three major flood control canals drain over 350,000 acres of land through West Palm Beach. The canal banks are colonized by invasive Australian pine, Brazilian pepper, and exotic grasses that produce allergenic pollen. During wet season, water surges carry organic matter that promotes mold growth along the entire canal corridor. Living near any canal in West Palm Beach means elevated mold and invasive-species pollen exposure.
West Palm Beach sits at a geographic and hydrological crossroads unlike any other Florida city. To its east lies the Lake Worth Lagoon — a 20-mile estuary that was once an enclosed freshwater lake fed by Everglades seepage. To its west, the Grassy Waters Preserve marks the remnant edge of what was once continuous Everglades sawgrass marsh extending all the way to the lagoon shore. Between these two water systems, a network of man-made canals — most notably the C-51 Canal — drains over 350,000 acres of land through the city, connecting Lake Okeechobee to the Atlantic coast. This engineered water infrastructure is the single most important factor shaping West Palm Beach's allergen environment.
The West Palm Beach Canal (C-51) was completed in 1925, connecting Lake Okeechobee to Lake Worth Lagoon and fundamentally altering the region's hydrology. Today, three major flood control canals drain a combined 350,000 acres of agricultural and developed land through the city. During South Florida's wet season, enormous volumes of freshwater surge through these canals, carrying agricultural runoff, organic matter, and nutrients that promote algal and mold growth along the entire canal corridor.
The canal levees themselves have become colonized by South Florida's most problematic invasive species: Australian pine (Casuarina), which produces allergenic pollen during winter months; Brazilian pepper, which blooms September through November with both airborne pollen and irritating cashew-family volatile oils; and exotic grasses like Burma reed and napier grass. These invasive species thrive on the disturbed upland habitat created by canal levees, creating linear allergen corridors that cut through residential neighborhoods across the city.
Lake Worth Lagoon has undergone one of the most dramatic ecological transformations of any water body in Florida. Originally an enclosed freshwater lake separated from the Atlantic by a barrier island, it was progressively converted to a brackish estuary through inlet construction, canal dredging, and the completion of the Intracoastal Waterway. Today, 81% of its shoreline is lined with bulkheads, and its original mangrove forests have been reduced from thousands of acres to just 283 acres.
For allergy sufferers, the lagoon is significant because its brackish water, remaining mangrove stands, and ongoing restoration areas (salt marsh grasses, oyster bars, maritime hammock) create an enormous mold and fungal spore source directly adjacent to West Palm Beach's most populated neighborhoods. Ocean water flowing through two inlets mixes with freshwater from the canal system, creating dynamic conditions where mold thrives in the decomposing organic matter that accumulates in this nutrient-rich estuary.
Grassy Waters Preserve, located in the northwest corner of West Palm Beach, is a 23-square-mile freshwater wetland that serves as the city's primary drinking water reservoir. This preserved Everglades remnant features sawgrass marshes, cypress swamps, and wet prairies that produce year-round mold spores from decomposing vegetation in standing water. While the preserve is an extraordinary natural asset, it also represents a significant allergen source for properties on the city's western edge. Prevailing easterly winds carry moisture and biological particulates from Grassy Waters across western residential neighborhoods.
At 26.7°N latitude, West Palm Beach sits firmly in the subtropical zone where freezing temperatures essentially never occur. This means the allergen calendar never resets. Oak trees begin pollinating in January — months before northern states see any pollen. Australian pine adds winter pollen along the lagoon shoreline and canal levees. Grass pollen runs April through October. Ragweed extends August through December. Brazilian pepper blooms September through November. And mold is elevated year-round due to the lagoon, canal system, Grassy Waters, and persistent 70%+ humidity. The only partial relief comes in December–January, when some tree and weed pollens briefly decline before oak season begins again.
West Palm Beach's unique combination of Everglades-to-ocean hydrology, three major drainage canals carrying 350,000 acres of runoff, an engineered estuary with ongoing ecological restoration, invasive species on canal levees, and a year-round subtropical allergen calendar creates an allergy environment that is genuinely distinct from inland Florida or Florida's Gulf Coast.
