How to connect?

Rosedale Golf Club's downtown Toronto ravine setting features sugar maple, oak, and basswood as the main pollen sources across this Stanley Thompson ravine design, with exposure varying between the deep, sheltered Mud Creek ravine and more open upper holes. Dense urban tree cover moderates pollen dispersal, while nearby ragweed and grass pollen build through the summer months.

When is pollen season in Toronto?
Tree pollen builds through April and peaks in May within the sheltered ravine, followed by grass pollen through June and July. Ragweed season runs from mid-August through September, often felt more acutely in the city due to limited air movement within the ravine corridor. Because the ravine limits airflow somewhat, sensitive golfers often notice pollen lingering longer here than at more exposed Toronto-area courses.
How often is the Toronto pollen forecast updated?

The Toronto pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Toronto 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 Toronto 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 Toronto, 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.
