How to connect?

Around Warrington, birch and sycamore are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Grass pollen from surrounding Warrington fields is significant through the summer months, carried in by light prevailing breezes. This mix of urban and rural influence gives Warrington a fairly typical pollen pattern for the wider region.

How often is the Warrington pollen forecast updated?

Does pollen in Warrington 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 Warrington 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 Warrington, 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.
