Aldershot's parks and the Basingstoke Canal corridor feature oak and birch as the main tree pollen sources, with exposure varying between these green areas and the more built-up town centre. Surrounding Hampshire and Surrey farmland and the heathland of the Blackwater valley contribute substantial grass and tree pollen, while the dry southeast climate provides fewer rainfall interruptions than in northern and western UK throughout the season.

How often is the Aldershot pollen forecast updated?

Does pollen in Aldershot 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 Aldershot 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 Aldershot, 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.
