Around Coleraine, oak and ash 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 region's typical south-westerlies. Overall exposure follows the broader regional trend, moderated somewhat by the town's parks and gardens.

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