Residents in Guildford dealing with hay fever usually point to birch and lime as the culprits, particularly in spring near parks and gardens. The nearby parkland nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the inland. This mix of urban and rural influence gives Guildford a fairly typical pollen pattern for the wider region.

How often is the Guildford pollen forecast updated?

Does pollen in Guildford 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 Guildford 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 Guildford, 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.
