Around Westhoughton, birch and sycamore are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Local farmland and hedgerows nearby add meaningful grass pollen through late spring and summer, especially under the area's changeable Atlantic weather. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.

Does pollen in Westhoughton 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 Westhoughton 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 Westhoughton, 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.
