Stavanger pollen forecast - today, tomorrow and the week ahead

On 25 June 2026, overall pollen levels in Stavanger are high. Cypress is the main contributor to airborne pollen, while grass remain at lower levels

On 26 June 2026, pollen conditions in Stavanger will be different from today, with birch at low levels, cypress at high levels and grass increasing

According to the five-day outlook, birch, cypress, and grass pollen levels are expected to gradually decrease, suggesting improving conditions later in the week.

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

Stavanger's pollen season runs from February through August, opening with alder and birch from February before birch peaks strongly through May. Grass follows through June and July. The Gandsfjord coastal position means onshore Atlantic winds can periodically disperse pollen, while surrounding Rogaland farmland and coastal heathland contribute substantial tree and grass pollen. The Atlantic climate means frequent rainfall provides regular interruptions throughout the season.

The Stavanger 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 Stavanger, 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.
