Local Environmental Conditions
Terrington St Clement's parks and green spaces feature oak and plane as the main tree pollen sources, with exposure varying between these greener areas and the more built-up town centre. Fields and hedgerows just outside town push grass pollen counts up noticeably once light prevailing breezes set in. This mix of urban and rural influence gives Terrington St Clement a fairly typical pollen pattern for the wider region.
Ask anyone with allergies in Terrington St Clement and they'll tell you it's oak and plane that cause the trouble. Oak tends to release pollen between April and May, before plane takes over, usually April to June. After that, grass pollen carries the season from May through to September, with June and July normally the toughest stretch. Worth factoring in if hay fever's ever been an issue for you here.

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