Local Environmental Conditions
The area around this part of Red Bluff is a mix of built-up land and woodland. Close to the Sacramento River, riverside trees such as poplar add to local tree pollen. The leading allergenic tree nearby is oak, with poplar close behind. Grass pollen is a substantial part of the local mix as well.
Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak and poplar are in full flower. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Red Bluff 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 Red Bluff 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 Red Bluff, 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.
