Copenhagen pollen forecast — Køge Bay coastline neighborhood

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

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

According to the five-day outlook, 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 Copenhagen. grass are also present but at lower levels. alder, birch, hazel, and willow are not currently active.

Copenhagen Køge Bay coastline runs along the southern Zealand coast south of Copenhagen, where marram grass, sea buckthorn, and introduced coastal planting are the main pollen sources along this exposed Køge Bay coastal setting. The Køge Bay position means onshore winds can frequently disperse pollen along this open coast, while birch peaks through April and May, grass from the coastal dune vegetation peaks through June and July, and mugwort extends into September throughout this southern Copenhagen coast.

The Copenhagen 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 Copenhagen, 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.
