Local Environmental Conditions
Nearby, within the neighborhood, a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. The general pattern described here holds fairly steady across nearby areas with similar land cover. Local wind exposure and land use can shift the exact mix slightly from block to block.
The waterside hazel and willow are consistently first to release pollen each year, climbing steadily from late winter into March. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed becomes the more dominant allergen from mid-August into October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

Does pollen in Hiawatha Township come from nearby or far away?

Are pollen levels in Hiawatha Township 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 Hiawatha Township, 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. |
