Positioned along the eastern Lake Ontario shoreline, Kingston follows a slightly later eastern Ontario timeline, with tree pollen emerging in mid-spring, grass building into early summer, and a moderate ragweed season shaped by the mix of lakeshore and limestone-plain terrain nearby.

The Kingston 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 Kingston, 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.
