Local Environmental Conditions
The center of Cromer is surrounded mainly by open water, which covers around 55% of the nearby area, with some built-up land and woodland. With running water close by, riverside vegetation contributes to the local mix. Allergenic trees in the wider area include maple and elm. Grasses and plantain growing in the surroundings are the main non-tree sources of pollen.
First to flower is elm, 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 midsummer and keep pollen in the air into early fall. The season closes with plantain from late spring into late summer. In warm, humid weather from midsummer into early fall, mold spores add to the mix, especially after rain.

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