Grant Park follows Atlanta's established pollen calendar, beginning with cedar and elm from February before oak peaks during March and April. Grass follows, peaking through April and May, while a modest late-summer weed pollen tail continues into September. Mild winters across the Southeast push the pollen calendar earlier than in most of the country, consistent with the wider Atlanta area.

The Atlanta pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Atlanta, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
