Local Environmental Conditions
Most of the area around Lake Hanska Park is farmland, with some open water and woodland. Close to Lake Hanska, lakeside vegetation adds to local tree pollen. There is plenty of grass pollen here too. Field margins, fallow strips and pasture around the farmland add further grass and weed pollen.
Tree pollen comes first, peaking in mid-spring. Then come the grasses, strongest in late spring and fading by early fall. Weeds on open ground add a smaller late peak from early summer into early fall. In warm, humid weather through summer, mold spores add to the mix, especially after rain. By late fall, as temperatures fall to around freezing, pollen levels are low again.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Lake Hanska Park 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 Lake Hanska Park, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
