Blackburn's parks, including Corporation Park, feature oak and birch as the main tree pollen sources, with exposure varying between these green areas and the more built-up town centre. The West Pennine Moors to the west contribute heather and grass pollen when winds blow from the west, while surrounding Lancashire farmland adds further grass and tree pollen across the area.

How often is the Blackburn pollen forecast updated?

Does pollen in Blackburn 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 Blackburn 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 Blackburn, 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.
