Copenhagen pollen forecast — Vesterbro neighborhood

On 24 August 2026, overall pollen levels in Copenhagen are low. Artemisia is the main contributor to airborne pollen, while grass remain at lower levels

On 25 August 2026, pollen conditions in Copenhagen will be different from today, with grass at low levels

According to the five-day outlook, artemisia and grass pollen levels will increase later in the week.

On 24 August 2026, Artemisia is the dominant pollen source in Copenhagen. grass are also present but at lower levels. hazel, cypress, and willow are not currently active.

Copenhagen Vesterbro's calendar mirrors the city pattern, with hazel and alder from January, birch peaking April into May, and grass through June and July, though this dense, historically working-class district west of the centre has less green space to soften pollen concentrations than Copenhagen's outer districts.

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.
