Amsterdam pollen forecast - today, tomorrow and the week ahead

On 20 July 2026, overall pollen levels in Amsterdam are moderate. Grass is the main contributor to airborne pollen, while cypress and artemisia remain at lower levels

On 21 July 2026, pollen conditions in Amsterdam will be similar to today, with cypress at low levels, grass at medium levels, artemisia at low levels

According to the five-day outlook, grass pollen levels are expected to gradually decrease, while cypress and artemisia pollen will increase, suggesting mixed conditions later in the week.

On 20 July 2026, Grass is the dominant pollen source in Amsterdam. cypress and artemisia are also present but at lower levels. willow, alder, birch, and hazel are not currently active.

Amsterdam's pollen season runs from January through August, opening with hazel and alder from January before birch peaks through April. Oak and ash follow through April and May, with grass peaking through June and July. The temperate oceanic climate means frequent rainfall provides regular interruptions throughout the season, while surrounding Dutch lowland farmland and polders contribute substantial grass and crop pollen across the flat, open polder landscape.

The Amsterdam 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 Amsterdam, 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.
