Local Environmental Conditions
In Radstock, birch and lime dominate the local tree pollen picture, with parks and tree-lined residential streets offering more exposure than the compact centre. The river valley nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the north-west. The relatively open, low-lying landscape lets pollen disperse readily across the area through the season.
Locals in Radstock usually notice birch first, with lime not far behind it. Birch pollen typically runs from March to May, then lime carries on from May until July. Then grass pollen takes the baton from May all the way to September, usually peaking in June and July — that's when most people really feel it. Something to plan around if pollen usually gets to you.

How often is the Radstock pollen forecast updated?

Does pollen in Radstock 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 Radstock 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 Radstock, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
