How to connect?

Residents in Altrincham dealing with hay fever usually point to rowan and birch as the culprits, particularly in spring near parks and gardens. Fields and hedgerows just outside town push grass pollen counts up noticeably once the prevailing Atlantic airflow set in. Seasonal peaks tend to track the wider regional pattern, tree pollen leading in spring and grass through summer.

Does pollen in Altrincham 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 Altrincham 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 Altrincham, 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.
