Local Environmental Conditions
The area around the heart of Croydon is mostly open grassland, with a good deal of woodland. Along a stream or river nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Around here, the woodland makes trees an important source; open grassland adds grass and weed pollen.
Tree pollen comes first, peaking in early spring. Then come the grasses, strongest in mid-spring and fading by mid-fall. A smaller weed peak follows from early summer into early fall. In this dry climate, pollen can linger in the air for long spells without rain. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.

How often is the Croydon pollen forecast updated?
The Croydon pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Croydon 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 Croydon 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 Croydon, 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. |
