On 25 June 2026, Cypress is the dominant pollen source in Vantaa. grass and birch are also present but at lower levels. willow, alder, and hazel are not currently active.

Vantaa's pollen season runs from February through August, opening with alder from February before birch peaks strongly through May. Grass follows through June and July. The Gulf of Finland coastal position and the Helsinki metropolitan setting mean onshore winds can periodically disperse pollen, while surrounding Finnish coastal woodland and farmland contribute substantial tree and grass pollen. Birch is particularly significant during the intense Finnish spring peak.

The Vantaa 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 Vantaa, 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.
