Local Environmental Conditions
Most of the area around the center of Horsens is built-up land, with some open grassland and woodland. Alder, willow and birch are among the allergenic trees nearby. Grasses also feature strongly, alongside plantain and mugwort among the weeds. Compared with most places, alder is especially widespread here, which makes it one of the key local allergens.
Willow and birch follow in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Grasses take over in midsummer, with temperatures around 15°C, and their pollen lingers into late summer. The season closes with plantain and mugwort from late spring into late summer. The alder period in early spring is usually the most intense time of year here.

Does pollen in Horsens 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 Horsens 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 Horsens, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
