Local Environmental Conditions
Odense's parks and the Odense River corridor feature oak, birch, and ash as the main tree pollen sources, with exposure varying between green areas and the more built-up city centre. Surrounding Funen farmland and the flat, open Danish landscape contribute substantial grass and crop pollen, while the coastal position on the fjord means onshore winds can periodically disperse urban pollen.
Odense's pollen season runs from January through August, opening with hazel and alder from January before birch peaks strongly through April and May. Grass pollen peaks through June and July. The Funen island position means coastal winds can periodically disperse pollen, while surrounding Danish farmland and the flat, open landscape contribute substantial grass and crop pollen. The maritime climate provides more frequent rainfall interruptions than in more continental cities.

When is pollen season in Odense?
How often is the Odense pollen forecast updated?
The Odense pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Odense come from nearby or far away?
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.
Are pollen levels in Odense based on measurements or forecasts?
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 Odense, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
