Tower District sees the same pollen timeline as the rest of Fresno, beginning with acacia and oak in January before olive extends the tree season through February and March. Grass pollen builds through March and April, and weed pollen lingers into early autumn once grass season ends. A long dry summer follows the spring peak, holding pollen counts low until autumn rains return, consistent with the wider Fresno area.

The Fresno 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 Fresno, 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.
