According to the district, 52 schools in the city aren't adequately cooled.
In a statement released on Monday night, the district said, "We will continue to prioritize student and staff safety. Accordingly, schools without adequate cooling systems have distributed Chromebooks to students in case hot temperatures require us to move to remote learning later in the week."
Earlier on Monday, the president of the Philadelphia Federation of Teachers, Arthur Steinberg, voiced concerns about the district's handling of the heat.
"It's a lucky break for students and staff this week that tomorrow is the Pennsylvania primary election, and schools will be closed. Considering Wednesday's high is forecast at 95 degrees, the District should show consideration for students and staff now and declare a virtual learning day."
The union said it would like the district to declare Wednesday a virtual learning day now so families in the city have time to prepare.
As we have reported, Philadelphia schools have had to dismiss early in warmer months because of extreme heat.
In April 2024, Eagles quarterback Jalen Hurts donated $200,000 for 10 schools in the city to get air conditioning.
