Perry Weather Wet Bulb Globe Temperature (WBGT) readings listed in the 3-widgets and chart below are NOT basic air temperatures.  WBGT readings are calculated using a WBGT device that takes into account factors like humidity, solar radiation, and wind speed to provide a more accurate assessment of heat stress.  

Directions:

1. 1. Identify the Perry Weather WBGT reading for your school. 
   1. Madera High = Blue Pyramid Schools
   2. Madera South = Purple Pyramid Schools
   3. Torres High = Red Pyramid Schools
2. 2. Find appropriate actions allowed per WBGT reading in the MUSD Outdoor Activity Guideline chart. 
3. 3. Schools must react appropriately within 30 minutes.

*Lightning Safety for Schools: Stay indoors until 30 minutes have passed since the last lightning strike within 10 miles of your school pyramid.  Use the lightning countdown timer on your school pyramid’s widget below to plan outdoor activities safely.
