Tallahassee Pollen & Allergy Guide

Tallahassee’s Local Pollen Count

Tallahassee does not currently have an active National Allergy Bureau (NAB) certified pollen counting station. AAAAI’s NAB data list includes a historical Tallahassee site, Station 58, run by allergist Ronald Saff, MD (AAAAI). Pollen Science, which tracks NAB-network monitoring locations, lists Tallahassee as inactive, and the only active Florida sites it lists are Jacksonville and Tampa. Dr. Saff told the Tallahassee Democrat back in 2014 that the city no longer had an official pollen counter.

The nearest active certified station is at Edward Waters University in Jacksonville, about 160 miles east. Jacksonville is also in North Florida, with the same oak and pine trees and a similar late-winter start, so its count is the most useful measured guide to where the regional tree season stands. See our Jacksonville guide for how that station works. It is not a Leon County measurement, though. Tallahassee sits inland, away from the Atlantic sea breeze, and day-to-day levels can differ. Most apps that show a “Tallahassee pollen count” are showing a modeled estimate, like the forecast on this page.

Pollen Count vs. Pollen Index

A pollen count is a measurement: grains of pollen per cubic meter of air, sampled over a past period, usually 24 hours. A pollen index like the 0–5 forecast above is a model’s estimate for today and the next few days. The two can disagree, especially on windy or rainy days. Use the forecast to plan ahead, and your symptoms plus the Jacksonville count to judge what has actually been in the air.

NAB levels differ by pollen type. A “high” grass day starts at just 20 grains per cubic meter, while trees need 90, so you can’t compare a grass number to an oak or pine number directly.

Why North Florida’s Tree Season Starts Early

UF/IFAS notes that Florida’s pollen season starts in North Florida first. That can sound backwards, since South Florida is warmer, but it follows the trees. North Florida’s urban forests are dominated by oaks, pines, red maple and sweetgum, deciduous and wind-pollinated trees that release pollen in a burst when they leaf out in late winter (UF/IFAS FR268). In South Florida, more of the landscape is tropical and subtropical species, and grass can pollinate most of the year.

Dr. Saff has said Tallahassee’s pollen season usually runs from January to May, and that when he arrived in the 1990s late February was the norm, while he now sees heavy pollen in January (Tallahassee Democrat). He has linked the earlier start to warmer winters that cue trees to pollinate sooner. In practice, Tallahassee’s spring feels more like south Georgia’s than Miami’s: a short, intense oak, pine and hickory peak, often in March, followed by grass in late spring and summer.

Colder winters do have an upside. Grass pollen usually tapers off after the first freezes, and weed pollen fades by late fall, so many Tallahassee allergy sufferers get a real break from about December until the trees start up again. South Florida rarely gets that pause.

Canopy Roads and the Tree Pollen Load

Tallahassee is known for its tree canopy. Leon County’s designated canopy road system covers 78 miles, 20 within the city limits and 58 in the unincorporated county, and each road has a protection zone that extends 100 feet from the centerline (Leon County). Roads like Miccosukee, Centerville, Old St. Augustine and Meridian are lined with large live oaks, along with sweetgum, hickory and pine.

That canopy is a big part of why spring is rough here. Oak and hickory pollen is nearly invisible and potent, while the yellow dust you see on cars is mostly pine, which is far less allergenic (UF/IFAS; Tallahassee Democrat). If you’re allergic to oak, a drive or bike ride under the canopy in March puts you right under the source. Keep car windows up with the A/C on recirculate.

Pollen and Big Tallahassee Events

Florida State University and FAMU spring events, Springtime Tallahassee in late March or early April, and spring football and outdoor graduations all land in or near the oak peak. If you’re coming from out of state, especially from somewhere where spring starts later, expect stronger tree pollen than you’re used to. Check the forecast on this page the day before, and take a long-acting antihistamine before you go rather than after symptoms start.
