How to connect?

This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing. That's on top of sycamore and oak, which are the main local tree pollen sources around Syston's parks and quieter streets. Surrounding Leicestershire farmland contributes substantial grass and tree pollen, moving into town when winds blow from the the surrounding hills.

How often is the Syston pollen forecast updated?

The Syston pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Syston 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 Syston 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 Syston, 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.
