Local Environmental Conditions
This site in Searles Valley is largely bare ground. With much of the immediate area made up of bare ground, local pollen production is limited, though pollen can still drift in from surrounding land. Roadside verges and patches of open ground provide further room for grasses and weeds.
Month by month, tree pollen comes first, peaking around early spring. Grasses take over from early spring, with the highest levels around late spring and pollen lingering until midsummer. Weeds on open ground add a smaller late peak from early summer into early fall. Here, temperatures range from around 10°C in the coldest month to around 30°C in the warmest, and rain is scarce.

Does pollen in Searles Valley 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 Searles Valley 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 Searles Valley, 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.
