Mestre's parks and the Venice Lagoon waterfront feature oak, plane, and poplar as the main tree pollen sources, with exposure varying between these green areas and the more built-up mainland city centre. Surrounding Venetian lagoon farmland and wetlands contribute substantial grass and reed pollen, while the flat, open lagoon landscape allows pollen to disperse widely and the Po Valley basin concentrates pollen under calm conditions.

How often is the Mestre pollen forecast updated?

Does pollen in Mestre 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 Mestre 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 Mestre, 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.
