Local Environmental Conditions
Ulsteinvik is a small Møre og Romsdal coastal town in Ulstein municipality where birch, alder, and coastal grassland are the main local pollen sources. The exposed Atlantic island and peninsula setting means strong onshore winds frequently disperse pollen, while the very wet western Norwegian Atlantic climate provides very frequent rainfall interruptions and birch peaks through April and May before grass contributes through June and July throughout this Sunnmøre coastal community.
Ulsteinvik's seasonal pollen activity covers the period from March through August, starting with alder and hazel pollen from March, before birch surges to its highest levels which carries through May. Grass follows close behind through the June-July stretch. With the steep fjord terrain and high rainfall around Ulsteinvik, the local climate makes the season feel a little different here than the national average suggests.

Does pollen in Ulsteinvik 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 Ulsteinvik 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 Ulsteinvik, 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. |
