Redding's pollen season opens with oak and valley oak from late January in the mild Shasta Valley climate. Pine follows through February and March, with grass peaking through April and May. The enclosed Sacramento Valley setting concentrates pollen under prevailing summer northerly winds, while surrounding northern California woodland and farmland contribute substantial tree and grass pollen. The hot, dry summer largely suppresses mid-season pollen.

The Redding 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 Redding, 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.
