Sundial Bridge follows Redding's established pollen calendar, beginning with acacia and oak from January then olive follows, running through February and March. Peak grass pollen arrives in March and April, and light weed pollen continues into early autumn. A long dry summer follows the spring peak, holding pollen counts low until autumn rains return.

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.
