Reno's high desert setting means cottonwood along the Truckee River corridor and introduced olive and ash trees are the main allergenic pollen sources, with exposure varying between these green riparian areas and the more arid urban core. Surrounding Great Basin sagebrush and grassland contribute seasonal shrub and grass pollen, while the valley setting concentrates pollen under prevailing winds.

When is pollen season in Reno?

The high desert setting and semi-arid climate mean fewer rainfall interruptions than in wetter US cities, while the Great Basin sagebrush contributes seasonal shrub pollen. The enclosed Truckee Meadows valley concentrates pollen under calm spring conditions.
How often is the Reno pollen forecast updated?

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

Does pollen in Reno 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 Reno 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 Reno, 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.
