Local Environmental Conditions
Fredericia's fortress-town streets, still ringed by 17th-century ramparts, are planted with lime and horse chestnut, while beech woodland covers much of the earthworks themselves. The narrow Lillebælt strait separating Jutland from Funen brings in coastal grasses alongside the usual inland crop pollen from surrounding farmland.
Fredericia's pollen season runs the familiar January-to-August arc, with hazel and alder opening the year, birch peaking April into May, and grass dominant through June and July. The town's position right on the narrow Lillebælt strait means cross-strait breezes usually keep pollen from settling for long.

How often is the Fredericia pollen forecast updated?
The Fredericia pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Fredericia 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 Fredericia 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 Fredericia, 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. |
