Local Environmental Conditions
Open grassland makes up around 33% of the area near this site in Algonquin, with a good deal of built-up land and some woodland. The damp ground beside running water nearby supports trees, shrubs and reeds, adding to local pollen. The allergenic tree mix nearby includes maple and oak. Grasses also feature strongly, alongside ragweed and plantain among the weeds.
Maple and oak lead the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by early fall. The season closes with ragweed and plantain from late summer into mid-fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Algonquin 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 Algonquin 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 Algonquin, 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.
