On 16 July 2026, Grass is the dominant pollen source in Grenaa. cypress are also present but at lower levels. artemisia, birch, hazel, willow, and alder are not currently active.

Grenaa's calendar starts with hazel and alder in January, birch peaks through April and May, and grass dominates June and July, the usual East Jutland progression. Sitting on the exposed tip of the Djursland peninsula, the town gets steady Kattegat winds that keep pollen moving through most of the season.

The Grenaa 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 Grenaa, 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.
