Around Cwmbran, oak and ash are the dominant species behind local tree pollen, with counts higher near parks than in the centre. The wider Torfaen countryside supplies additional tree and grass pollen, particularly when the area's changeable Atlantic weather carry it toward the built-up area. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.

How often is the Cwmbran pollen forecast updated?
The Cwmbran pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Cwmbran 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 Cwmbran 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 Cwmbran, 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.
