Littlehampton's parks and green spaces feature oak and plane as the main tree pollen sources, with exposure varying between these greener areas and the more built-up town centre. Grass pollen from surrounding West Sussex fields is significant through the summer months, carried in by the area's changeable Atlantic weather. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.

How often is the Littlehampton pollen forecast updated?

Does pollen in Littlehampton 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 Littlehampton 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 Littlehampton, 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.
