Tucson's desert setting means native palo verde, mesquite, and introduced olive trees are the main allergenic pollen sources, with exposure varying between greener irrigated parks and the more arid urban core. Surrounding Sonoran Desert scrub and grassland contribute seasonal shrub and grass pollen, while the mountain ranges encircling the city create varied microclimates and pollen exposure across different neighbourhoods.

When is pollen season in Tucson?
Tucson's pollen season differs from most US cities, with introduced olive producing intense pollen from February through April. Native desert species including palo verde and mesquite contribute from March through May. The dry desert summer largely suppresses mid-season pollen, with a secondary grass peak following monsoon rains from July through September. The mountain ranges encircling the city create varied microclimates and pollen exposure across different neighbourhoods.
How often is the Tucson pollen forecast updated?

The Tucson pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Tucson 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 Tucson 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 Tucson, 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.
