Weather Guidelines for Elementary Schools

During the hot days of summer, early fall, and late spring, there are frequent weather alerts. The following guidelines will apply to all elementary campuses. There will be no outside activity if one of the following alerts occurs:
  • "Feels like" temperature is above 100*
  • "Feels like" temperature below 32*
  • Air quality levels in red or purple- unhealthy levels**
*Grade level team leaders will view and enter the school’s zip code, and view the needed "feels like" temperature. The "feels like" temperature considers the wind chill factor and heat index, adjusts temperature accordingly, and is an accurate measurement of how hot or cold it really feels.

**Teachers are to check daily air quality indicators and sign up for daily alerts via email at

Air Quality
Air Quality Level Outdoor Activity
Purple No outside activity
Red No outside activity
Orange Possible respiratory alert

PISD restricts all elementary outdoor activity, when in PURPLE or RED air quality levels, which indicate unhealthy ozone levels for all students, even those with no respiratory health concerns.

Parents of students with asthma, respiratory problems, or environmental allergies significant enough to cause health concerns, must provide the teacher with a one-time written notice stating that they would like their child to stay indoors on ORANGE alert days or with specific temperatures, if different than those temperatures above.
