Jacksonville, Florida sits along the humid subtropical coast of Northeast Florida, where mild winters, warm wet summers, and a long growing season create one of the most prolonged allergy calendars in the country.
Tree pollen typically ignites the season as early as late January, with oak—particularly live and laurel oak—driving the most intense symptoms from February through April, alongside pine, cedar, elm, bayberry, sweetgum, and birch. The greenish-yellow dusting of pine and oak pollen on cars is a familiar spring marker.
As tree counts taper, grass pollen takes over from April through September, dominated by Bahia, Bermuda, and Johnson grasses that thrive in the region's sandy soils and heat.
Weed season follows in late summer and fall, with ragweed leading from August into November, joined by pigweed, lamb's quarters, dog fennel, and sorrel. Overlap between late-spring trees and early grasses, and again between summer grasses and fall weeds, often intensifies symptoms for multi-sensitive individuals.
Beyond pollen, Jacksonville's persistent humidity, frequent rainfall, and coastal air fuel year-round outdoor and indoor mold, while dust mites flourish in warm homes and urban ozone can compound irritation.
Overall, the city's allergy profile is defined by a nearly year-round pollen cycle amplified by humidity-driven mold.
