Local Environmental Conditions
This site in Downieville is heavily wooded. A nearby park adds mown lawns and planted trees to the local pollen mix. Allergenic trees nearby include oak. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees. Much of the pollen in dense woodland is released high in the canopy, where the wind carries it easily.
The pollen year opens with oak, peaking around mid-spring. Grass pollen builds from mid-spring, peaks around early summer and stays noticeable until late summer. Weeds on open ground add a smaller late peak from early summer into early fall. Temperatures range from around freezing in the coldest month to around 25°C in the warmest, with most rain falling in the cooler months.

Does pollen in Downieville 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 Downieville 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 Downieville, 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.
