Local Environmental Conditions
Tyresö relies on spruce, birch, and oak in its parks and green belts as the principal tree pollen sources. The countryside bordering Lake Drevviken and the archipelago beyond is a reliable source of grass and crop pollen through the warmer months. Tyresö shows a vegetation pattern typical of Swedish towns its size, driven by nearby countryside rather than residential and outdoor recreation.
Tyresö's pollen season runs from February through August, opening with alder from February before birch peaks strongly through May. Grass takes over from birch through the summer months of June and July. Sitting close to Lake Drevviken and the archipelago beyond, Tyresö sees pollen counts that can rise or fall quickly with changing weather fronts. The combination of spruce forest and open farmland keeps grass and tree pollen present well into late summer.

How often is the Tyresö pollen forecast updated?

Does pollen in Tyresö 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 Tyresö 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 Tyresö, 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. |
