Seasonal peaks tend to track the wider regional pattern, tree pollen leading in spring and grass through summer. That's on top of birch and oak, which are the main local tree pollen sources around Llanidloes's parks and quieter streets. The wider Powys countryside supplies additional tree and grass pollen, particularly when light prevailing breezes carry it toward the built-up area.

Does pollen in Llanidloes 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 Llanidloes 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 Llanidloes, 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.
