Local Environmental Conditions
Tree pollen in Moreton-in-Marsh comes mostly from oak and plane, with parks and mature gardens standing in contrast to the more built-up centre. The wider Gloucestershire countryside supplies additional tree and grass pollen, particularly when inland breezes from the surrounding countryside carry it toward the built-up area. This mix of urban and rural influence gives Moreton-in-Marsh a fairly typical pollen pattern for the wider region.
Pollen season in Moreton-in-Marsh really gets going with oak, followed not long after by plane. Grass then takes over from May right through September, peaking around June and July for most people. Expect oak pollen roughly from April to May, and plane keeps things going from April right through to June. Handy to bear in mind before booking that garden party.

Does pollen in Moreton-in-Marsh 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 Moreton-in-Marsh 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 Moreton-in-Marsh, 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. |
