On 16 July 2026, Grass is the dominant pollen source in Oslo. alder, artemisia, birch, hazel, cypress, and willow are not currently active.

In Frogner, the pollen season plays out between February and August, with the first releases of alder and hazel from about February, before birch surges to its highest levels before easing after May. Grass follows for June and July. With the suburban parks and nearby farmland around Oslo, Oslo's local climate plays a bigger role in the local pollen pattern than the calendar alone.

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.
