Oak and birch in the woods pick up where the earlier species leave off, typically the year's sharpest tree-pollen spell, centered on April and May. Late spring sees grass pollen build steadily toward a peak in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

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 Brampton, 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.
