Reading's riverside parks, including Forbury Gardens, and tree-lined streets are the main urban pollen sources. Exposure varies across the town between green corridors and built-up areas. The surrounding countryside, including the Chilterns and North Wessex Downs, produces higher and more widespread pollen than the urban centre.

How often is the Reading pollen forecast updated?

Does pollen in Reading 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 Reading 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 Reading, 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.
