Local Environmental Conditions
Set along the Aust-Agder Skagerrak coast around the town of Lillesand, this municipality opens the pollen season with hazel from January before birch peaks through April and May. Grass peaks through June and July before mugwort extends exposure into September. The Skagerrak coastal position means onshore winds can periodically disperse pollen, while the mild southern Norwegian coastal climate advances the season making this one of Norway's earlier-starting coastal municipalities.
The yearly pollen cycle in Lillesand kommune runs from February through August, opening gently with alder and hazel beginning in February, before birch pollen takes hold most strongly which carries through May. Grass follows and holds through June and July. With the sheltered skerries and coastal woodland near Lillesand kommune, the local climate gives the season a character that's shaped as much by geography as by month.

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