Local Environmental Conditions
The area around the heart of Leigh-on-Sea is mostly built-up land, with a good deal of woodland and some open water. The leading allergenic tree nearby is hazel, with maple close behind. Grasses and weeds such as plantain and mugwort round out the local mix. Around here, planted trees and mown lawns are the main sources in the built-up parts.
Hazel opens the pollen season in late winter. Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple is in full flower. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Later, plantain and mugwort keep weed pollen in the air from late spring into late summer.

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