Local Environmental Conditions
This site in Charlton is heavily wooded. With this much woodland around, trees are an important local pollen source. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen. Much of the pollen in dense woodland is released high in the canopy, where the wind carries it easily.
Tree pollen comes first, peaking in mid-spring. Then come the grasses, strongest in early summer and fading by early fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

How often is the Charlton pollen forecast updated?
The Charlton pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Charlton 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 Charlton 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 Charlton, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
