Weather+Guidelines

Make sure you check the heat index and temperature before you go outside for recess. The following are the guidelines that are in the MISD student handbook:

When the temperature or heat index rises to 95 degrees or the ozone alert is orange, outdoor recess or activities should be limited to 10 minutes. When the temperature or heat index rises to 100 or the ozone alert is red or purple no outside recess or activities should be allowed, except of normal dismissal procedures, but caution will be used during dismissal time to keep exposure to heat at a minimum.
