Local Environmental Conditions
Around 96% of the area near this site in Mount Shasta is woodland. With this much woodland around, trees are an important local pollen source. Grass pollen is a substantial part of the local mix as well. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Tree flowering starts the season, reaching its height around mid-spring. Grass pollen builds from mid-spring, peaks around early summer and stays noticeable until late summer. Later, weeds flowering on open and disturbed ground keep some pollen in the air from early summer into early fall. Winters average around freezing and summers around 25°C, with most rain falling in the cooler months.

How often is the Mount Shasta pollen forecast updated?
The Mount Shasta pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Mount Shasta 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 Mount Shasta 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 Mount Shasta, 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. |
