Set on a border town on the Rainy River at the edge of the boreal forest, International Falls's landscape is defined by boreal spruce-fir forest alongside bog and muskeg vegetation and paper birch stands, the main contributors to seasonal pollen exposure. Local parks and open ground tend to see higher pollen counts than the denser urban core. Small local variations aside, this pattern holds fairly steady from year to year.

How often is the International Falls pollen forecast updated?
The International Falls pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in International Falls come from nearby or far away?
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.
Are pollen levels in International Falls based on measurements or forecasts?
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 International Falls, 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.
