On 25 June 2026, there are no significant pollen types in St. Petersburg.

St. Petersburg's subtropical setting on the Pinellas Peninsula produces an extended pollen season, with oak and pine contributing from January through spring. Grass pollen peaks through March and April, with a secondary peak after summer rains. The coastal position on Tampa Bay and the Gulf of Mexico means onshore breezes can periodically disperse pollen from multiple directions, while surrounding wetlands and coastal grasslands contribute substantial grass and reed pollen.

The St. Petersburg 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 St. Petersburg, 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.
