Local Environmental Conditions
This location in Halton Hills is surrounded mainly by woodland, which covers around 51% of the nearby area, with a good deal of built-up land and some open grassland. Running water nearby means riverside trees such as poplar are part of the local pollen picture. Of the allergenic trees nearby, maple matters most, while birch and ash also contribute. There is plenty of grass pollen here too.
Maple, birch and ash lead the season in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. By late fall, pollen levels are low again.

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 Halton Hills, 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.
