Local Environmental Conditions
Hommelvik is a small Trøndelag coastal village in Malvik municipality on the inner Trondheim Fjord where birch, alder, and fjordside farmland vegetation are the main local pollen sources. The inner fjord position means onshore winds can periodically disperse pollen, while the Atlantic-influenced Trøndelag climate provides frequent rainfall interruptions and birch peaks through April and May before grass from surrounding Malvik farmland contributes through June and July.
Hommelvik sees its pollen season begins in March and continues through August, with alder and hazel marking the early stage around March, then birch dominates with a pronounced peak which carries through May. Grass pollen rounds out Hommelvik's season extending across June and July. With the broad agricultural plains typical of this part of Trøndelag, the local climate gives this particular area its own seasonal quirks worth knowing about.

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