Grass pollen from surrounding Surrey fields is significant through the summer months, carried in by the region's typical south-westerlies. On top of that, oak and birch are the two species driving most tree pollen in Leatherhead, especially around parks and green corridors. This mix of urban and rural influence gives Leatherhead a fairly typical pollen pattern for the wider region.

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. Handy to bear in mind before booking that garden party.
How often is the Leatherhead pollen forecast updated?

Does pollen in Leatherhead 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 Leatherhead 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 Leatherhead, 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.
