Local Environmental Conditions
Around 78% of the area near this location in Truckee is woodland. Along running water nearby, trees such as willow and poplar grow in the damper ground and add their own pollen. Of the allergenic trees nearby, poplar matters most, while oak and willow also contribute. Grass pollen is plentiful, while mugwort leads among the weeds.
Over the course of the year, tree pollen comes first, with poplar, oak and willow in flower through spring. Grass pollen builds from mid-spring, peaks around early summer and stays noticeable until late summer. Mugwort keeps pollen in the air from midsummer into early fall. Locally, temperatures range from around freezing in the coldest month to around 20°C in the warmest, with most rain falling in the cooler months.

How often is the Truckee pollen forecast updated?

Does pollen in Truckee 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 Truckee 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 Truckee, 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 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. |
