Local Environmental Conditions
The landscape around this site in La Grange is largely open grassland, with a good deal of woodland. Woodland on all sides makes trees an important local pollen source. Grasses are also a significant pollen source here. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in early spring. Grasses take over in mid-spring and keep pollen in the air into mid-fall. Weeds on open ground add a smaller late peak from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

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 La Grange 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 La Grange, 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.
