Local Environmental Conditions
Sandvika's suburban setting in Akershus features birch, alder, and oak as the main tree pollen sources in parks and along the Sandvikselva River corridor, with exposure varying between green areas and the more built-up areas. Surrounding Bærum woodland and farmland contribute substantial tree and grass pollen, while the fjord position means onshore winds from the Oslofjord can periodically disperse pollen.
The yearly pollen cycle in Sandvika covers the period from February through August, kicking off with alder and hazel already by February, before birch surges to its highest levels and staying strong through May. Grass pollen then carries the season into the following June and July. With the moderating effect of the Oslofjord on the local climate near Sandvika, the local climate shapes a locally distinct version of the broader Norwegian pollen season.

How often is the Sandvika pollen forecast updated?

Does pollen in Sandvika 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 Sandvika 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 Sandvika, 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. |
