Local Environmental Conditions
Spread across Helgeland islands and coastal headlands, Herøy in Nordland opens the pollen season with alder from March before birch peaks through May. Grass from surrounding island farmland peaks through June and July, while the Norwegian Sea island position means strong onshore winds frequently disperse pollen and the subarctic Atlantic climate produces a compressed season with regular rainfall interruptions throughout.
The yearly pollen cycle in Herøy kommune covers the period from March through August, beginning with alder and hazel picking up from March, before the season's main birch surge arrives continuing right through June. Herøy kommune then sees grass pollen continue into June and July. With the exposed coastline and frequent sea winds around Herøy kommune, the local climate makes the season feel a little different here than the national average suggests.

Does pollen in Herøy kommune, Nordland 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 Herøy kommune, Nordland 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 Herøy kommune, Nordland, 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. |
