Local Environmental Conditions
Located not far from here, this area has a waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix. As with most local readings, actual levels can vary somewhat with short-term weather swings. The general pattern described here holds fairly steady across nearby areas with similar land cover.
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. Grass pollen counts rise through late spring, reaching their peak around June, with ragweed climbing to its own high point from mid-August through October.

Are pollen levels in Deer Valley Golf 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 Deer Valley Golf 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. |
