The wider Pembrokeshire countryside supplies additional tree and grass pollen, particularly when the prevailing Atlantic airflow carry it toward the built-up area. On top of that, birch and oak are the two species driving most tree pollen in Narberth, especially around parks and green corridors. Hay fever sufferers here typically notice symptoms peaking in late spring, then again during the summer grass season.

Does pollen in Narberth 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 Narberth 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 Narberth, 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.
