Local Environmental Conditions
Around 88% of the area near this site in Susanville is woodland, with some open grassland. The damp ground beside a stream or river nearby supports trees, shrubs and reeds, adding to local pollen. So much tree cover makes trees an important source of pollen locally. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in late spring. Then come the grasses, strongest in early summer and fading by late summer. Rain is heaviest in winter, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around 5°C, pollen levels are low again. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

How often is the Susanville pollen forecast updated?

Does pollen in Susanville 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 Susanville 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 Susanville, 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. |
