Around Gorseinon, birch and oak are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Local farmland and hedgerows nearby add meaningful grass pollen through late spring and summer, especially under the area's changeable Atlantic weather. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.

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 Gorseinon 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 Gorseinon, 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.
