On 25 June 2026, Grass is the dominant pollen source in Mollet. alder, birch, hazel, cypress, and willow are not currently active.

Mollet's Besòs River valley setting and the Montseny massif proximity produce a sub-Mediterranean season opening with hazel, olive, and cypress in January, with cypress contributing through spring, before plane and oak peak through March and April. Grass from surrounding Catalan farmland peaks through May and June, while mugwort and nettle extend exposure into September.

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

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.

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 Mollet, 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.
