St. Boniface Cathedral sits along the Red River amid mature streetscape trees, giving it a fairly strong spring tree pollen bloom shaped by riverside forest cover, with the cathedral's gardens and surrounding parkland sustaining a modest, steady grass pollen presence through the warmer months of the Winnipeg summer.

The Winnipeg 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 Winnipeg, 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.
