The vegetation around Stillwater, on rolling prairie in north-central Oklahoma, is dominated by tallgrass prairie and post oak, with eastern red cedar adding further seasonal pollen exposure. Exposure varies with proximity to green space versus the more built-up parts of Stillwater. As with most of the region, counts tend to build gradually rather than spike overnight.

How often is the Stillwater pollen forecast updated?

Does pollen in Stillwater 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 Stillwater 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 Stillwater, 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.
