Local Environmental Conditions
Here, a short distance from here, along the damp banks, hazel and willow release some of the year's first tree pollen. Nearby, not far from here, a mix of oak and birch trees, birch in particular a notorious spring allergen source. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Near the bank, hazel and willow lead the seasonal calendar, topping out well before most other trees start releasing pollen, around February and March. Further into spring, the area's oak and birch stands drive the pollen count, building to its sharpest point across April and May. Grass pollen climbs toward a June peak, with ragweed climbing to its own high point from mid-August through October.

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. |
