Galway's coastal setting on Galway Bay features oak, ash, and birch as the main tree pollen sources in parks and along streets, with exposure varying between green areas and the more built-up city centre. Surrounding Connacht farmland and the Atlantic-facing coastline contribute substantial tree and grass pollen, while the very wet oceanic climate provides frequent rainfall interruptions to exposure throughout the season.

When is pollen season in Galway?
Galway's pollen season runs from January through August, opening with hazel and alder from January before ash and birch peak through April and May. Grass pollen peaks through June and July. The Atlantic oceanic climate means very frequent rainfall provides regular interruptions throughout the season, making Galway's pollen exposure more fragmented than in continental European cities, though grass pollen can be intense during dry spells in June and July.
How often is the Galway pollen forecast updated?

The Galway pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Galway 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 Galway 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 Galway, 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.
