Oklahoma City woke up under clear skies on Sunday, July 26, 2026, but the nice, calm morning is not sticking around. Forecast highs are near 102°F, and heat index values are expected to surge into the mid to upper 100s by midafternoon. Overnight, temperatures will only dip to around 80°F, so residents should not count on much relief after sunset.
Heat Advisory and Afternoon Outlook
The National Weather Service has issued a Heat Advisory from 11 a.m. to 9 p.m. CDT Sunday for the metro, warning of heat index values up to 109°F and a daytime high near 102°F. South-southwest winds of 9 to 13 mph, with gusts up to about 20 mph, will be common and could make outdoor work feel even more draining. Forecasters urge people to limit strenuous activity from midday into the evening and to drink plenty of water, according to NWS Norman.
Where to Find Relief
The City of Oklahoma City maintains a heat health resource hub and a downloadable list of public cooling centers. Residents without reliable air conditioning are encouraged to call 2-1-1 or visit the city's resource page for locations and hours. Libraries, malls and community centers remain dependable, air-conditioned spots to ride out the worst of the afternoon heat.
Week Ahead and Fire Weather Concerns
The upper ridge overhead is expected to keep widespread triple-digit temperatures in place into early next week, with highs near 102 to 103°F on Monday and Tuesday and only low chances for rain. Drier air across western Oklahoma could drop humidity into the teens and create pockets of elevated fire weather risk during afternoon hours. Overnight lows near 80°F will continue to offer little cooling. For more background on the hot pattern, see our earlier coverage: triple-digit heat bears down.
Legal Protections
Oklahoma rules generally prohibit utilities from disconnecting electric service when the heat index is forecast to reach 101°F or higher. Customers facing shutoff are advised to contact their utility and call 2-1-1 for assistance and payment programs. The city's heat hub also lists help for vulnerable households and bill assistance options, per the City of Oklahoma City.
