In Runcorn, oak and ash dominate the local tree pollen picture, with parks and tree-lined residential streets offering more exposure than the compact centre. Surrounding Halton farmland contributes substantial grass and tree pollen, moving into town when winds blow from the east. Seasonal peaks tend to track the wider regional pattern, tree pollen leading in spring and grass through summer.

How often is the Runcorn pollen forecast updated?
The Runcorn pollen forecast is updated four times daily. See the timestamp below for the most recent update.
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.
