How to connect?

Cleveland's lakefront and river green network, anchored by Rockefeller Park and the Cuyahoga River corridor, features oak, birch, and maple as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Lake Erie onshore breezes can periodically disperse urban pollen, while surrounding Ohio farmland and woodland contribute additional grass and tree pollen under prevailing westerly winds.

How often is the Cleveland pollen forecast updated?

Does pollen in Cleveland 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 Cleveland 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 Cleveland, 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.
