Local Environmental Conditions
National Automobile Museum, a museum building in the downtown core near the Truckee River, shares its vegetation profile with the broader Reno area, so pollen exposure here tracks the same regional sources found across the city. Any difference from the citywide pattern here tends to be minor rather than a distinct microclimate.
National Automobile Museum follows Reno's established pollen calendar, beginning with palo verde and mesquite from January with mulberry taking the lead through February. Grass pollen rises through March and April, and a second grass and weed peak follows the summer monsoon rains from July through September. The hot desert climate concentrates the main spring season, with little rainfall to interrupt pollen release, a defining feature of the local season.

When is pollen season in Reno?
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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
