On 17 July 2026, pollen conditions in Sandviken will be different from today, with cypress, grass continuing to decline

According to the five-day outlook, artemisia, cypress, and grass pollen levels will increase later in the week.

On 16 July 2026, Cypress is the dominant pollen source in Sandviken. grass and artemisia are also present but at lower levels. alder, birch, hazel, and willow are not currently active.

In Sandviken, alder gets the pollen season underway in February, with birch building to its main peak by May. June and July then belong to grass pollen, which builds steadily as birch fades. Surrounding Gästrikland forest shapes the local pollen dynamics, with prevailing winds off this area able to shift concentrations day to day. Steel manufacturing activity in the area has little direct bearing on pollen levels, which instead track the regional spruce and farmland cover.

The Sandviken pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 Sandviken, 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.
