Local Environmental Conditions
Most of the area around the center of East Grinstead is woodland, with a good deal of built-up land. Of the allergenic trees nearby, hazel matters most, while birch and maple also contribute. Grass pollen is significant here, and plantain contributes weed pollen. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
The pollen year starts in late winter, when hazel flowers. Birch and maple follow in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer and keep pollen in the air into late summer. Plantain brings a final peak from late spring into late summer.

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