Record-breaking heat in Colorado this week has prompted public schools without air conditioning to close or announce plans to send students home early.

More than 30 Denver schools are calling “heat days,” according to a district press release. Most schools are releasing students early Wednesday and Thursday, but four schools are closing altogether for at least one day this week.

Other Colorado school districts have announced similar closures. All schools in the Poudre district, based in Fort Collins, and the Thompson district, based in Loveland, will release students two hours early on Wednesday and Thursday. Most Poudre schools don’t have air conditioning, the district said in a press release.

Forty-eight Denver campuses don’t have air conditioning. (See the list here.) Thirty-one of those are not scheduled to get it anytime soon. But 17 campuses are slated to get air conditioning later this fall or next school year with funding passed by Denver voters in 2020.

That funding was earmarked to add air conditioning at 24 Denver campuses. Work has been completed at seven campuses and is nearly complete at eight more. Supply chain issues have slowed the work at those eight campuses, district officials said. The district is scheduling work at the remaining nine campuses to start next summer.

Denver has posted 62 days this year above 90 degrees, the third most on record.
