How to connect?

Columbus' urban green network, anchored by Scioto Audubon and the Olentangy River corridor, features oak, maple, and ash as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Ohio farmland and the flat, open landscape contribute substantial grass and crop pollen that disperses readily under prevailing westerly winds.

Grass pollen peaks through June and July, with ragweed extending the season into September. The flat, open Ohio farmland landscape allows substantial grass and crop pollen to disperse readily across the city, while the humid continental climate produces well-defined and intense seasonal peaks.
How often is the Columbus pollen forecast updated?

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

Does pollen in Columbus come from nearby or far away?

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.

Are pollen levels in Columbus based on measurements or forecasts?

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 Columbus, 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.
