The relatively open, low-lying landscape lets pollen disperse readily across the area through the season. That's on top of oak and plane, which are the main local tree pollen sources around Marazion's parks and quieter streets. The wider Cornwall countryside supplies additional tree and grass pollen, particularly when onshore breezes carry it toward the built-up area.

Does pollen in Marazion 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 Marazion 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 Marazion, 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.
