Local Environmental Conditions
This area, practically next door, 50 meters off, has hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Woodland where oak stands alongside birch, the latter especially aggressive as an allergen; this sits close enough to matter, at 50m. A park whose turf grass and ornamental plantings feed local grass and ragweed pollen levels; this sits about 400 meters off.
Water-edge hazel and willow are usually the first allergenic trees active here, topping out well before most other trees start releasing pollen, around February and March. The area's oak and birch trees pollinate through mid-to-late spring, building to its sharpest point across April and May. Grass pollen takes over next, building to a peak around June, and ragweed later takes the lead from mid-August through October.

Does pollen in Bryants Court 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 Bryants Court 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 Bryants Court, 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. |
