On 16 July 2026, Grass is the dominant pollen source in Mississauga. birch, cypress, oak, willow, alder, ambrosia, and artemisia are not currently active.

Tree pollen from maple and oak peaks in May along the Credit River corridor, followed by grass pollen through June and July on the more open fairways. Ragweed then builds from mid-August through September, the period when most golfers with seasonal allergies notice the greatest discomfort. Golfers sensitive to pollen often prefer early spring or October play, once both tree pollen and ragweed have largely subsided for the year.

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

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.

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.
