Stockholm Nacka Nature Reserve occupies the rocky forest landscape east of Stockholm, where birch, pine, and oak are the main pollen sources across this classic Stockholm eastern archipelago forest. The Baltic Sea archipelago proximity means onshore winds can periodically disperse pollen, while birch peaks intensely through May, grass peaks through June and July, and mugwort extends into September throughout this popular eastern Stockholm nature reserve.

The Stockholm 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 Stockholm, 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.
