Local Environmental Conditions
This site in Central Valley (historical) is surrounded mainly by open water, which covers around 95% of the nearby area. Close to a stream or river, riverside vegetation contributes to what is in the air. With much of the immediate area made up of open water, local pollen production is limited, though pollen can still drift in from surrounding land. Oak is among the allergenic trees in the wider area.
Oak leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in late spring and fading by early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Central Valley (historical) 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 Central Valley (historical) 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 Central Valley (historical), 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.
