How to connect?

Great Dunmow's parks and green spaces feature oak and birch as the main tree pollen sources, with exposure varying between these greener areas and the more built-up town centre. Fields and hedgerows just outside town push grass pollen counts up noticeably once the region's typical south-westerlies set in. Locals with allergies tend to plan around two peaks a year rather than one long stretch.

Does pollen in Great Dunmow 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 Great Dunmow 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 Great Dunmow, 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.
