Ogden's pollen season opens with elm and cottonwood from late February, followed by oak and ash through April and May. Grass pollen peaks through June and July. The enclosed Weber Valley setting between the Wasatch Mountains and the Great Salt Lake concentrates pollen under calm conditions, particularly during spring temperature inversions. The high altitude and semi-arid climate mean the season is shorter but can be intense during peak periods.

The Ogden 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 Ogden, 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.
