Local Environmental Conditions
Around 79% of the area near this location in Fort Irwin is bare ground, with some scrubland. 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. Grasses, pigweed and ragweed growing in the surroundings are the main non-tree sources of pollen.
Over the course of the year, grass pollen dominates, building from mid-spring to a peak around late spring and lasting until midsummer. Pigweed keeps pollen in the air from early summer into early fall, with ragweed in flower from late summer into mid-fall. Winters average around 5°C and summers around 30°C, with most rain falling in the cooler months.

Does pollen in Fort Irwin 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 Fort Irwin 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 Fort Irwin, 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.
