Local Environmental Conditions
Built-up land makes up around 47% of the area near the heart of Leonberg, with a good deal of woodland. The allergenic tree mix nearby includes hazel and maple. Grass pollen is significant here, and plantain and pigweed contribute weed pollen. Locally, street trees, gardens and lawns supply most pollen in the built-up parts.
The pollen year starts in late winter, when hazel flowers. Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple is in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into late summer. Later, plantain and pigweed keep weed pollen in the air from late spring into early fall. By late fall, pollen levels are low again.

How often is the Leonberg pollen forecast updated?
The Leonberg pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Leonberg 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 Leonberg 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 Leonberg, 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. |
