Minneapolis Mississippi River Gorge runs through the steep river gorge south of the Falls of St. Anthony, where cottonwood, willow, and oak are the main pollen sources along this remarkable urban river gorge. The Mississippi valley concentrates pollen under calm conditions, while birch peaks through May, grass peaks through June and July, and mugwort extends into September throughout this remarkable Minneapolis Mississippi River gorge parkway.

The Minneapolis 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 Minneapolis, 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.
