Tree pollen builds through April and peaks in May across the course's dense forest cover, followed by grass pollen through June and July. Ragweed season runs from mid-August through September, typically the most noticeable stretch for golfers with seasonal allergies in the northern GTA. The course’s dense forest cover can hold pollen a little longer after calm mornings, so breezier afternoons often suit sensitive golfers better.

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 Vaughan, 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.
