Local Environmental Conditions
The area around the center of West Mersea is a patchwork of built-up land, open water and woodland. The damp ground beside standing water nearby supports trees, shrubs and reeds, adding to local pollen. Grasses and weeds such as pigweed and mugwort round out the local mix. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Tree pollen comes first, peaking in mid-spring. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Pigweed and mugwort bring a final peak from midsummer into mid-fall. Warm, damp weather through summer also raises mold spore levels. By late fall, as temperatures fall to around 10°C, pollen levels are low again.

How often is the West Mersea pollen forecast updated?

Does pollen in West Mersea 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 West Mersea 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 West Mersea, 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. |
