Residents in Rhondda dealing with hay fever usually point to oak and plane as the culprits, particularly in spring near parks and gardens. The the wider farmland belt nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the north-west. This mix of urban and rural influence gives Rhondda a fairly typical pollen pattern for the wider region.

How often is the Rhondda pollen forecast updated?

Does pollen in Rhondda 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 Rhondda 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 Rhondda, 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.
