Local Environmental Conditions
Around 93% of the area near this part of Squaw Valley is woodland. Running water nearby means riverside vegetation is part of the local pollen picture. Locally, the surrounding woods make trees an important source. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Tree pollen comes first, peaking around early spring. Grasses take over from mid-spring, with the highest levels around late spring and pollen lingering until midsummer. Later, weeds flowering on open and disturbed ground keep some pollen in the air from early summer into early fall. Temperatures range from around 5°C in the coldest month to around 30°C in the warmest, with most rain falling in the cooler months.

Does pollen in Squaw Valley 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 Squaw Valley 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 Squaw Valley, 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.

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. |
