How to connect?

Locals with allergies tend to plan around two peaks a year rather than one long stretch. That's on top of oak and plane, which are the main local tree pollen sources around Plymouth's parks and quieter streets. The stretch of open moorland nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the west.

How often is the Plymouth pollen forecast updated?

Does pollen in Plymouth 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 Plymouth 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 Plymouth, 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.
