New Feature: Wet Bulb Globe Temperature (WBGT) Forecast

Earth Networks announces a new Wet Bulb Globe Temperature (WBGT) Forecast feature to improve heat safety. Learn how to use WBGT effectively to reduce injuries and avoid heat stress illness. 


Wet Bulb Globe Temperature (WBGT) is a measure of heat stress in direct sunlight, which is crucial for athletes, students, and people participating in outdoor activities or exercise. Monitoring WBGT helps reduce heat stress illness, and injuries. Earth Networks just added a new feature, WBGT Forecast, which makes it even easier to plan for and respond to high heat conditions.


The Wet Bulb Globe Temperature (WBGT) Forecast displays a daily and hourly forecast value for WBGT at your weather station’s location, in the Online Weather Center (OWC).


Your community, employees, and visitors will now be able to view the WBGT forecast high for the current day, and the following 5 days. This new forecasting capability is beneficial for planning outdoor activities safely. The WBGT Forecast is available to Earth Networks customers subscribing to heat safety packages.

Who should be monitoring WBGT?

WBGT is the gold standard for heat stress management, which is why Earth Networks offers Heat Safety Packages which include WBGT monitoring and alerting. The WBGT Forecast feature now enables the ability to plan outdoor activities and heat stress accommodations to avoid the hottest days or hours of the day.

  1. Schools can use WBGT forecasts to help maintain compliance with state heat safety regulations for student athletes. The WBGT forecast indicates when the WBGT surpasses the maximum heat stress levels that are safe for outdoor practice and games.
  2. Sports Complexes and Parks can be sure to keep organized athletic practices, games, players and spectators safe.
  3. Airports can avoid heat illness for crew working outdoors in ground operations activities such as baggage handling, catering, marshaling, and maintenance.
  4. Companies can maintain compliance with OSHA’s OSH Act, keeping outdoor workers in loading docks, logistics, transportation and maintenance out of danger.
  5. Military Bases and Installations can keep those participating in training, operations and events safe.
  6. Any Organization With Outdoor Activities will know when conditions permit outdoor exertion, which is essential for worker safety and the operational regulations for organizations, businesses, and facilities.

What can you do with the WGBT Forecast?

Use the new WBGT Forecast to plan your outdoor activities. You don’t have to wait until conditions are dangerous to take action. WGBT is your new proactive heat safety management tool.
