Texas schools will soon be required to use a specific metric to determine the safety of outdoor activities. The University Interscholastic League will mandate the use of wet bulb globe temperature readings starting August 1. This metric takes into account temperature, humidity, wind speed, and solar radiation.

The requirement applies to all Texas schools, including those in the Lubbock area. The guidelines for outdoor activities are categorized based on the wet bulb globe temperature reading. Further details on the guidelines and classifications, including the specific category for West Texas, are available from the University Interscholastic League.
