Local Environmental Conditions
This site in Reno is densely built up. Lawns and planted trees in a nearby park add to local grass and tree pollen. Among allergenic trees nearby, poplar leads, followed by elm and willow. Grasses also feature strongly, alongside pigweed and mugwort among the weeds. Around here, planted trees and mown lawns are the main sources in the built-up parts.
Elm opens the pollen season in early spring. Poplar and willow follow in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by late summer. Later, pigweed and mugwort keep weed pollen in the air from early summer into early fall.

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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
