Runcorn's parks and the River Mersey and Manchester Ship Canal corridor feature oak and birch as the main tree pollen sources, with exposure varying between these green areas and the more built-up town centre. Surrounding Cheshire farmland and the Mersey valley meadows contribute substantial grass and tree pollen, while the flat lowland landscape allows pollen to disperse readily across the town under prevailing southwesterly winds.

Does pollen in Runcorn 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 Runcorn 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 Runcorn, 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.
