Sønderborg pollen forecast - today, tomorrow and the week ahead

On 16 July 2026, overall pollen levels in Sønderborg are moderate. Grass is the main contributor to airborne pollen

On 17 July 2026, pollen conditions in Sønderborg will be different from today, with artemisia at low levels, cypress at low levels and grass increasing

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

On 16 July 2026, Grass is the dominant pollen source in Sønderborg. willow, alder, artemisia, birch, hazel, and cypress are not currently active.

On the island of Als, Sønderborg's season starts with hazel and alder in January, birch peaks through April, and grass dominates June and July much like the rest of Jutland. The narrow Sønderborg Sound funnels wind unpredictably, so some still days see pollen linger noticeably longer than in more open parts of South Jutland.

The Sønderborg 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 Sønderborg, 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.
