Local Environmental Conditions
Around 77% of the area near the heart of Angwin is woodland. Along a watercourse nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Oak is the most prominent allergenic tree nearby, with maple also present. Grass pollen is plentiful, while plantain leads among the weeds.
Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak and maple are in full flower. Grasses take over in late spring and keep pollen in the air into early fall. Plantain flowers through much of the warmer half of the year. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Angwin 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 Angwin 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 Angwin, 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. |
