How to connect?

Tree pollen in Richmond Park comes mostly from oak and plane, with parks and mature gardens standing in contrast to the more built-up centre. The stretch of open moorland nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the the coast. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.

Oak gets going around April and tapers off by May, before plane takes over, usually April to June. Not a bad idea to stock up on antihistamines before it all kicks off.
How often is the London pollen forecast updated?

The London pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in London 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 London 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 London, 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.
