Local Environmental Conditions
Here, within the neighborhood, a waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species. This area, in the surrounding area, has tree cover made up mostly of oak and birch, both significant spring allergen sources. Local wind exposure and land use can shift the exact mix slightly from block to block.
The water-adjacent hazel and willow are early risers, starting well before the main spring rush, topping out around March. Once hazel fades, oak and birch in the woods carry the season forward, typically landing in April and May. Grass pollen rises through late spring toward a June high point, handing off to ragweed, which peaks from mid-August through October.

Are pollen levels in Belmont Hills Country Club 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 Belmont Hills Country Club, 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. |
