WBGT and Heat Index Monitoring
On-site Heat Stress Monitoring for Precise Readings
Set it and forget it
Never worry about having to set up tripods or do readings every 15 minutes during outdoor activities again. Perry Weather automatically monitors WBGT and records readings every 15 minutes, so you can ensure you’re in compliance without the hassle.
Accurate black bulb sensor
Perry Weather stations include a precise WBGT monitor with a large 3.5″ black bulb sensor, offering more reliable readings than smaller handheld devices.
Eliminate human errors
Competing handheld devices are prone to inaccuracies due to factors like shadows and calibration errors. Perry Weather’s stationary unit minimizes these issues, ensuring consistent and dependable heat readings by eliminating human errors

Frequently asked questions
Have questions about how Perry Weather monitors WBGT and heat stress? Check out some of our frequently asked questions.
What is Wet Bulb Globe Temperature?
Wet bulb globe temperature measures heat stress in direct sunlight, giving a better idea of how the human body will react in hot and humid weather.
WBGT readings, unlike regular temperature readings, combine the effects of:
-ambient temperature
-wind speed
-relative humidity
-sun angle
-cloud cover (solar radiation)

Why do I need to monitor WBGT?
By taking in these other factors, WBGT is a more practical, accurate, and useful measurement of heat as it relates to the body, especially when dealing with outdoor activities and sports programs.
Said plainly, WBGT is the best measurement to prevent exertional heat stroke and the effects of extreme heat.
States like Georgia have begun mandating the use and monitoring of WBGT for all high school outdoor athletic programs. The University Interscholastic League (UIL) has recommended Texas athletic programs to start using WBGT and moving away from heat index.
How does Perry Weather measure Wet Bulb Globe Temperature?
There are two complex formulas involved in calculating Wet Bulb Globe Temperature. To truly get WBGT measurement right, having an on-site WBGT sensor like the one offered with Perry Weather’s weather station is the way to go. Perry Weather’s outdoor weather station is equipped with a more capable 3.5” diameter black bulb, providing precise and timely WBGT readings.
Why is Perry Weather better than handheld devices for measuring WBGT?
Unlike WBGT, heat index is a measurement that only takes into account air temperature and humidity. Think of it as the “feels-like” temperature in a shaded area. Heat Index is measured in the shade rather than the sun, and doesn’t factor in cloud cover (solar radiation), wind, or sun angle.
For situations where precision and heat safety are required, like in outdoor sports practice or outdoor events, WBGT is preferred. Learn more about heat index vs WBGT
How do we determine our WBGT policies?
If you need help crafting a heat stress and WBGT policy for your needs, Perry Weather offers policy consultations backed by expert meteorologists to make sure your policy is accurate, tailored, and comprehensive.

How do we know when our WBGT is too high for outdoor activities?
The data from the black bulb sensor on Perry Weather weather stations is reflected onto your user-friendly website and mobile dashboard. Depending on the reading and your policy, clear and instructive alerts are then delivered via SMS alerts, PA warnings, and more.
So, if your WBGT reading is at dangerous levels, your staff members can receive warning alerts to take action.
