June 1st – June 30th, 2024

THSADA Region VIII WBGT Data

The chart below shows how outdoor workouts would be impacted each day from June 1 – June 30, 2024 based on the current UIL Heat Stress Activity Guidelines for Region 8 (San Marcos, San Antonio, Laredo).

What does this report mean?

This graph displays data for June 2024, showing how outdoor workout conditions vary throughout the day based on Wet Bulb Globe Temperature (WBGT) zones.

The horizontal axis represents different times of day, from 6 AM to 8 AM.
The vertical bars for each time slot are divided into colored sections, with each color corresponding to a WBGT zone as defined by UIL WBGT Activity Guidelines:

Green: Normal Activities

Yellow: Use Discretion

Orange: 2 Hrs. Practice Max

Red: 1 Hr. Practice Max

Black: No Outdoor Workouts

The numbers within each colored section indicate how many days out of the 30 days in June fall into that particular WBGT zone at that specific time.
For example, at 6 AM:

26 days allow for normal activities
4 days recommend using discretion

This graph helps coaches and athletes plan when it’s safest to conduct outdoor practices in June, showing how heat stress risk changes throughout the day.

Key Observations

What time of day has the best chance of a full practice?

Morning sessions are ideal, as they are minimally impacted by heat and comply with UIL WBGT guidelines. For uninterrupted practice, mornings between 6 AM to 9 AM are your best option as only 1 day with outdoor practice before 9am would be impacted.

What is the best time to practice in the afternoon?

Between 12 PM and 6 PM, the optimal time for a full 2-hour practice is between 12 PM and 3 PM, with a minimum of 13 occurrences being shortened to 1 hour practice.

What times can I not practice? 

In this date range, 2 practices would be canceled or halted due to WBGT Activity Guidelines. At least 13 days with outdoor practice between 3pm and 6pm would be limited to a maximum of 1 hour.
