Local Environmental Conditions
TPC Scottsdale – Stadium Course occupies the Sonoran Desert floor beneath the McDowell Mountains in Scottsdale, where the course's vegetation is dominated by desert landscaping with palo verde, turf fairways, and saguaro accents, the main contributors to seasonal pollen exposure. Seasonal timing here follows the same regional pattern typical of courses in this part of the country.
TPC Scottsdale – Stadium Course follows Scottsdale's established pollen calendar, beginning with palo verde and mesquite from January with mulberry taking the lead through February. A grass pollen peak follows through March and April; summer monsoon rains from July through September trigger a second, smaller pollen peak. The hot desert climate concentrates the main spring season, with little rainfall to interrupt pollen release, which shapes conditions at TPC Scottsdale – Stadium Course much as it does elsewhere in Scottsdale.

Does pollen in Scottsdale 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 Scottsdale 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 Scottsdale, 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. |
