Local Environmental Conditions
Set on wooded parkland in north Houston, Champions Golf Club in Houston features loblolly pine forest alongside live oak and Bermuda grass fairways as the leading sources of pollen around the course. As with most golf courses, maintained turf areas see somewhat different exposure than the wooded rough.
Houston's regional pollen pattern holds at Champions Golf Club, with mountain cedar first appearing in December before oak and elm peaks during March. A grass pollen peak follows through April and May; ragweed extends the season into October. Mountain cedar's December-through-February peak is one of the most intense tree pollen events in the US, a defining feature of the local season.

How often is the Houston pollen forecast updated?
The Houston pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Houston 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 Houston 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 Houston, 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. |
