In Downham Market, oak and birch dominate the local tree pollen picture, with parks and tree-lined residential streets offering more exposure than the compact centre. The wider Norfolk countryside supplies additional tree and grass pollen, particularly when prevailing westerlies carry it toward the built-up area. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.

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 Downham Market 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 Downham Market, 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.
