Vänersborg's tree pollen comes mainly from oak, birch, and oak growing in parks and along residential streets rather than the compact centre. Farmland close to Lake Vänern's southern outlet adds a steady stream of grass and crop pollen through the growing season. Seasonal exposure in Vänersborg therefore depends heavily on how close residents are to parks versus the denser city core.

By early summer, grass pollen becomes the dominant driver through June and into July. Air moving across Lake Vänern's southern outlet periodically clears or concentrates pollen depending on which way the wind is blowing. What keeps the season going into August here is largely the surrounding oak forest and open agricultural land.
How often is the Vänersborg pollen forecast updated?

Does pollen in Vänersborg 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 Vänersborg 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 Vänersborg, 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.
