Local Environmental Conditions
Woodland and built-up land share the area around this part of Oroville, plus some open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Oak is the most prominent allergenic tree nearby. Grass pollen is significant here, and plantain contributes weed pollen. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and oak is in full flower. Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. Later, plantain keeps weed pollen in the air from mid-spring into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels. By early winter, pollen levels are low again.

How often is the Oroville pollen forecast updated?

Does pollen in Oroville 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 Oroville 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 Oroville, 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. |
