Local Environmental Conditions
The area around this site in Mississauga is mostly built-up land, with some woodland. A nearby park adds mown lawns and planted trees to the local pollen mix. The leading allergenic tree nearby is maple, with oak close behind. Grass pollen is plentiful, while ragweed and plantain lead among the weeds.
Maple and oak lead the season in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by early fall. Ragweed and plantain bring a final peak from late summer into mid-fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Mississauga come from nearby or far away?
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.
Are pollen levels in Mississauga 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 Mississauga, 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.
