Sugar Grove lies in the Illinois River basin, not far from the Spoon River and Rock Run Rookery Preserve. The surrounding landscape is dominated by bottomland hardwood forest and prairie remnants. The Spoon River winds through the wider area, its banks favoring moisture-loving trees such as willow and alder. Local vegetation still varies with soil type and drainage.

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 Sugar Grove 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 Sugar Grove, 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.
