Around Harrietsham, plane and lime are the dominant species behind local tree pollen, with counts higher near parks than in the centre. The belt of hedgerows nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the west. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.

Does pollen in Harrietsham 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 Harrietsham 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 Harrietsham, 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.
