Local Environmental Conditions
Spread along the outer Oslofjord coast to the Skagerrak, Larvik opens the pollen season with hazel from January before birch peaks through April and May. Grass from surrounding farmland peaks through June and July before mugwort extends exposure into September. The Larviksfjord and Skagerrak coastal position means onshore winds can periodically disperse pollen, while the mild coastal Vestfold climate advances the season compared to more inland Norwegian municipalities throughout.
Larvik kommune works through a pollen season that runs its course from February to August, with alder and hazel arriving first around February, before birch peaks strongly through to May. From there, grass pollen continues extending across June and July. With the mix of farmland and woodland around Larvik kommune, the local climate makes the season feel a little different here than the national average suggests.

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