Local Environmental Conditions
In Havanah Hills, here, within the local area, the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring. This area, close by, has oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
In Havanah Hills, the bank's hazel and willow kick off the pollen season ahead of the rest, leading off the pollen calendar, with a peak generally falling in late winter. By mid-spring, oak and birch in the woods take over, generally peaking somewhere between April and May. Through late spring, grass pollen climbs steadily toward its June peak, and ragweed later takes the lead from mid-August through October.

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

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 Havana 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 Havana 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. |
