Local Environmental Conditions
Sand Hills Golf Club's Nebraska Sandhills setting features native prairie grasses, sand cherry, and cottonwood as the main pollen sources across the natural duneland course, with exposure varying between the open prairie fairway areas and the more vegetated dune sections. The surrounding Sandhills prairie landscape contributes a distinctive and regionally unique pollen environment, while the flat, open Great Plains landscape allows pollen to disperse widely and mugwort extends exposure into September.
Sand Hills Golf Club – Championship Course follows North Platte's established pollen calendar, beginning with elm and cottonwood from March before ash extends the tree season through April. Grass pollen builds through May and June, and ragweed pollen builds through late summer into September. Wide-open plains terrain lets pollen travel long distances on the prevailing wind.

Does pollen in North Platte 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 North Platte 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 North Platte, 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. |
