Minneapolis woke up in a steam bath on Tuesday, July 14, 2026. Early-morning temperatures were already in the low 70s under clear, humid skies, and forecasters say the afternoon will crank up to near 97°F, with heat-index values up to about 100°F. Overnight lows are expected to linger in the mid-70s, which means little to no relief after sunset. The National Weather Service has issued an Extreme Heat Warning for Hennepin County through 9 p.m. Thursday, July 16.
When The Heat Peaks
The most punishing stretch is expected Tuesday and Wednesday, with daily highs in the mid- to upper-90s and only a modest cooldown on Thursday. Showers are not likely to arrive until Friday. According to the National Weather Service, heat-index values could top out around 100°F while winds stay generally light out of the southwest to west.
What To Expect And How To Stay Safe
The sticky humidity will turn the afternoon into a slog, raising the risk of heat-related illness for older adults, infants and anyone who has to work outside. City officials are urging residents to stick to air-conditioned spaces as much as possible, drink plenty of water and check in on neighbors. And the standing rule still applies: never leave children or pets in parked cars. For more details and a list of air-conditioned public locations, see the City of Minneapolis.
Where To Cool Off
Public libraries, community centers and other city-run buildings will double as cooling spots during the peak heat hours, with many locations listed on the city website. If you have to be outside, try to schedule heavy activity for early morning or evening, take frequent breaks in the shade and keep water on hand. If someone shows signs of heat stroke, such as confusion, fainting or a very high body temperature, call 911 right away.
