Perched on the north shore of the Gulf of Saint Lawrence, Sept-Iles experiences a short, maritime-cooled pollen season, with boreal forest producing a late, compressed spring tree bloom, while the gulf's cold air and rocky coastal terrain keep grass and ragweed exposure minimal throughout the year.

The Sept-Iles 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 Sept-Iles, 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.
