Local Environmental Conditions
The area around the center of Jansenville is a mix of open grassland and scrubland, plus some built-up land. In the immediate area, open grassland adds grass and weed pollen; scrubland contributes pollen from shrubs, grasses and herbs. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
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. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down. Between late fall and the first tree flowering, pollen levels stay low, with midwinter usually the quietest time.

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