Local Environmental Conditions
The course at National Golf Links of America, on windswept Long Island dunes and sandy links land in the Southampton area, is shaped by fescue grasses and scrub oak, with beach plum adding further seasonal exposure. As with most golf courses, maintained turf areas see somewhat different exposure than the wooded rough.
As a golf course within Southampton, National Golf Links of America follows the same seasonal pollen curve, opening with maple and elm from March before birch and oak extends the tree season through April and May. Grass follows, peaking through June and July, while mugwort and nettle extend exposure into September. Cold winters give way to a fast, concentrated spring pollen ramp-up across the region, a defining feature of the local season.

When is pollen season in Southampton?
How often is the Southampton pollen forecast updated?

Does pollen in Southampton 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 Southampton 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 Southampton, 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. |
