Redlands's San Bernardino Mountain foothill setting features olive, citrus, and oak as the main tree pollen sources, with the historic citrus groves contributing particularly distinctive local crop pollen. Exposure varies between the foothill residential neighborhoods and the more built-up commercial corridors along Redlands Boulevard, while the San Bernardino Mountain backdrop creates downslope wind conditions that concentrate pollen in the valley floor areas.

How often is the Redlands pollen forecast updated?
The Redlands pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Redlands 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 Redlands 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 Redlands, 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.
