Local Environmental Conditions
In Godstone, oak and birch dominate the local tree pollen picture, with parks and tree-lined residential streets offering more exposure than the compact centre. Surrounding Surrey farmland contributes substantial grass and tree pollen, moving into town when winds blow from the south. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.
In Godstone, the pollen calendar starts with oak and rolls straight into birch. You'll usually see oak pollen from around April through May, then birch carries on from March until May. Don't forget grass, either — it runs May to September and usually causes the most trouble in June and July. Something to plan around if pollen usually gets to you.

How often is the Godstone pollen forecast updated?

Does pollen in Godstone 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 Godstone 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 Godstone, 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. |
