Local Environmental Conditions
Around Feltwell, oak and birch are the dominant species behind local tree pollen, with counts higher near parks than in the centre. The nearby woodland nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the the surrounding hills. Locals with allergies tend to plan around two peaks a year rather than one long stretch.
Pollen season in Feltwell really gets going with oak, followed not long after by birch. Don't forget grass, either — it runs May to September and usually causes the most trouble in June and July. Oak tends to release pollen between April and May, then birch carries on from March until May. Good to know if you're planning anything outdoors that time of year.

How often is the Feltwell pollen forecast updated?

Does pollen in Feltwell 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 Feltwell 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 Feltwell, 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. |
