Residents in Chorley dealing with hay fever usually point to birch and sycamore as the culprits, particularly in spring near parks and gardens. The wider Lancashire countryside supplies additional tree and grass pollen, particularly when shifting coastal winds carry it toward the built-up area. This mix of urban and rural influence gives Chorley a fairly typical pollen pattern for the wider region.

Does pollen in Chorley 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 Chorley 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 Chorley, 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.
