Trees along the Sangamon River, such as willow and alder, are usually first to release pollen, typically peaking in late winter into March. Tree pollen peaks next around Comlara Park, where oak and hickory dominate the canopy through most of April and May. Farther out toward Salt Creek and a remnant tallgrass prairie preserve, tree pollen tends to follow this same rough schedule.

The Grandview 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 Grandview, 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.
