Local Environmental Conditions
The landscape around the heart of Orangeville Township is heavily wooded. With this much woodland around, trees are an important local pollen source. Roadside verges and patches of open ground provide further room for grasses and weeds. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in early summer and keep pollen in the air into early fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

Are pollen levels in Orangeville Township 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 Orangeville Township, 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.
