Tree pollen in Greenford comes mostly from oak and birch, with parks and mature gardens standing in contrast to the more built-up centre. Surrounding Ealing farmland contributes substantial grass and tree pollen, moving into town when winds blow from the south-west. Locals with allergies tend to plan around two peaks a year rather than one long stretch.

How often is the Greenford pollen forecast updated?

Does pollen in Greenford 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 Greenford 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 Greenford, 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.
