WBGT Forecast | Video: How to use this tool.Limit strenuous work (eg., carrying heavy loads).Schedule work earlier or later in the day.Acclimatize workers starting the first day working in the heat and after any extended absences.The Occupational Safety and Health Administration (OSHA) recommends protective measures for outdoor work: For instance, The American College of Sports Medicine bases its guidelines for the intensity of sport practices on WBGT, and it is therefore utilized by athletic programs in many school districts. WBGT can be used to inform activity modifications during exercise or outdoor work. It’s a particularly effective indicator of heat stress for active populations such as outdoor workers and athletes. WBGT uses temperature, humidity, wind, solar radiation, and other weather parameters. What is Wet Bulb Globe Temperature (WBGT)? Check out this handout and video to learn about WBGT. Also, strong winds, particularly with very hot, dry air, can be extremely hazardous.

Since heat index values were devised for shady, light wind conditions, exposure to full sunshine can increase heat index values by up to 15☏. NWS also offers a Heat Index chart for areas with high heat but low relative humidity. The National Weather Service will initiate alert procedures when the Heat Index is expected to exceed 105°-110☏ (depending on local climate) for at least 2 consecutive days. The red area without numbers indicates extreme danger. As an example, if the air temperature is 96☏ and the relative humidity is 65%, the heat index-how hot it feels-is 121☏. To find the Heat Index temperature, look at the Heat Index Chart above or check our Heat Index Calculator. The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature. Each of these tools integrate other weather parameters to provide a deeper level of information beyond what the actual air temperature can tell us. The following tools can inform the issuance of NWS official heat watches, warnings, and advisories. NWS has multiple tools to assess the potential for heat stress due to extreme temperatures.
