Local Environmental Conditions
The course at TPC Louisiana, on a wetland-edged course built on reclaimed bayou land west of the city in the New Orleans area, is shaped by bald cypress wetlands and live oak groves, with paspalum turf fairways adding further seasonal exposure. Exposure varies across the course depending on proximity to trees versus open fairways.
TPC Louisiana, a golf course in New Orleans, opens its pollen season with oak and pine from January with cedar joining in and continuing through February. Grass pollen rises through March and April, and pigweed and ragweed keep weed pollen elevated into October. Warm, humid Gulf Coast conditions stretch the spring pollen season longer than in most of the country throughout the year.

Does pollen in New Orleans 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 New Orleans 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 New Orleans, 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. |
