Local Environmental Conditions
In Brightwood Hills Golf Course, along the damp banks, hazel and willow release some of the year's first tree pollen, not far from here. Located in the surrounding area, this area has oak and birch trees, with birch pollen especially potent during its brief spring window. The park's turf and planted trees form a small but steady source of grass and ragweed pollen; this sits within the neighborhood's edge.
For Brightwood Hills Golf Course, the woodland's oak and birch trees become the main pollen source by mid-spring, reaching its high point through April and into May. Grass pollen counts rise through late spring, reaching their peak around June, with ragweed then rising to the fore from mid-August through October.

Does pollen in New Brighton 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 New Brighton 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 New Brighton, 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. |
