Residents in Newcastle County Down dealing with hay fever usually point to alder and birch as the culprits, particularly in spring near parks and gardens. The wider Newry, Mourne and Down countryside supplies additional tree and grass pollen, particularly when the area's changeable Atlantic weather carry it toward the built-up area. This mix of urban and rural influence gives Newcastle County Down a fairly typical pollen pattern for the wider region.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Newcastle County Down 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 Newcastle County Down, 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.
