Oldham's parks, including Alexandra Park, and the River Medlock headwaters corridor feature birch and oak as the main tree pollen sources, with exposure varying between these green areas and the more built-up town centre. Surrounding Lancashire farmland and the Pennine moorland to the east contribute heather and grass pollen, while frequent rainfall typical of the western Pennine fringe provides regular interruptions to exposure throughout the season.

Does pollen in Oldham 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 Oldham 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 Oldham, 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.
