The wider Belfast countryside supplies additional tree and grass pollen, particularly when shifting coastal winds carry it toward the built-up area. On top of that, birch and hazel are the two species driving most tree pollen in Titanic Quarter, especially around parks and green corridors. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.

How often is the Belfast pollen forecast updated?

Does pollen in Belfast 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 Belfast 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 Belfast, 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.
