Oklahoma City woke up in a sweat on Tuesday, July 28, 2026, staring down another day of dangerous summer heat. High temperatures are expected to climb to about 102°F this afternoon, with humidity driving heat-index readings into the 105–110°F range in some neighborhoods. Overnight will not offer much of a break, as lows are forecast to hold near 80°F, and a light south-southwest breeze around 6–9 mph will provide only modest relief.
Heat Advisory In Effect
The National Weather Service has issued a Heat Advisory for the metro from 11 a.m. to 9 p.m. CDT Tuesday. According to NWS Norman, heat-index values could approach 109°F, and officials warn that the combination of heat and humidity increases the risk of heat-related illness.
Afternoon Outlook And Week Ahead
The hottest stretch will run from late morning through late afternoon. Skies should stay mostly sunny and dry, with highs near 102°F today, about 101°F on Wednesday, and near 100°F on Thursday. A small chance of late-night storms may develop Thursday night into Friday across parts of northern Oklahoma, but the more noticeable break from the extreme heat is expected to arrive late Friday into the weekend.
Where To Find Relief
The City of Oklahoma City heat hub has a downloadable list of public cooling centers and pools. Residents without reliable air conditioning are advised to call 2-1-1 for the latest locations and hours. Local relief spots listed by the city include the Ronald J. Norick Downtown Library (300 Park Ave.) and the Ralph Ellison Library (2000 NE 23rd St.), and many branch libraries and YMCAs are keeping their doors open during peak heat hours.
What You Should Do
Limit outdoor activity during the hottest part of the day, drink plenty of water, and check on older relatives and neighbors who may be more vulnerable. If someone shows signs of heat exhaustion or heat stroke, such as heavy sweating, dizziness, confusion, or fainting, move them to a cool place and call 9-1-1 if symptoms are severe.
