Local Environmental Conditions
Lærdalsøyri is a small Vestland village at the inner Sognefjord in Lærdal municipality where birch, hazel, and orchard vegetation are the main local pollen sources. The enclosed inner Sognefjord valley concentrates pollen under calm conditions, while the notably dry Lærdal microclimate means fewer rainfall interruptions than almost anywhere else in western Norway and birch peaks through April and May before grass contributes through June and July.
Lærdalsøyri moves through a pollen season that begins in March and continues through August, starting quietly with alder and hazel around March, before birch peaks strongly through to May. The season then shifts to grass pollen for June and July. With the combination of high peaks and deep fjords surrounding Lærdalsøyri, the local climate leaves this area with a noticeably local twist on the general pattern.

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