Kensington's parks, including Hyde Park and Kensington Gardens, feature plane and oak as the main tree pollen sources alongside extensive grass from the royal parkland, with exposure varying between these green areas and the densely built urban streets. The royal parks are a significant local pollen source, while the urban heat island effect of central London extends the season at both ends compared to outer London.

How often is the Kensington pollen forecast updated?

Does pollen in Kensington 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 Kensington 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 Kensington, 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.
