London Epping Forest forms one of London's largest ancient woodlands on the northeastern edge of Greater London, where oak, hornbeam, and birch are the dominant pollen sources across this extensive ancient forest. The enclosed forest concentrates pollen under calm conditions, while birch and oak peak intensely through April and May, grass from forest glades peaks through June and July, and mugwort extends into September throughout this remarkable London ancient forest.

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.

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.
