Local Environmental Conditions
Tree pollen in Walton-on-the-Naze comes mostly from oak and beech, with parks and mature gardens standing in contrast to the more built-up centre. Grass pollen from surrounding Essex fields is significant through the summer months, carried in by cooler northerly winds. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.
Locals in Walton-on-the-Naze usually notice oak first, with beech not far behind it. Oak pollen typically runs from April to May, with beech picking up between April and May. Then grass pollen takes the baton from May all the way to September, usually peaking in June and July — that's when most people really feel it. Good to know if you're planning anything outdoors that time of year.

Are pollen levels in Walton-on-the-Naze 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 Walton-on-the-Naze, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
