Local Environmental Conditions
The area around this site in Oakville is mostly woodland, with some built-up land. The damp ground beside running water nearby supports trees, shrubs and reeds, adding to local pollen. Among allergenic trees nearby, pecan leads, followed by maple and oak. Grass pollen adds noticeably to the overall load. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Tree pollen peaks in late spring, when the weather warms to around 10°C and pecan, maple and oak are in full flower. Grasses take over in early summer and keep pollen in the air into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Oakville 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 Oakville, 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.
