Oslo Bærum (Sandvika) spreads across the Bærum municipality west of Oslo, where birch, oak, and pine are the main pollen sources across this suburban and nature-rich municipality. The Oslofjord shoreline means onshore winds can periodically disperse pollen along the fjord sections, while birch peaks through April and May, grass peaks through June and July, and mugwort extends into September throughout this large Oslo western suburban municipality.

The Oslo 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 Oslo, 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.
