On 9 August 2026, Ambrosia is the dominant pollen source in Dayton. artemisia, cypress, and grass are not currently active.

By mid-spring, oak and birch in the woods take over, reaching its high point through April and into May. Late spring sees grass pollen build steadily toward a peak in June, handing off to ragweed, which peaks from mid-August through October. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

The Dayton 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 Dayton, 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.
