Oklahoma City is waking up warm and sticky this Sunday, June 28, with clear skies and temperatures already near 79°F. That relatively tolerable start will not last long. By afternoon, forecasters expect the mercury to jump to around 97°F, with heat-index values topping 100°F and south winds cranking up enough to make it all feel even hotter. If your weekend plans involve festivals, yard work or sports, think shade, sunscreen and a lot of water.
Afternoon Heat And Near-Record Nights
A Heat Advisory is in effect from 1 p.m. to 8 p.m. CDT Sunday as the combination of heat and humidity pushes the apparent temperature into the low 100s. South winds are expected to blow around 22 mph with gusts up to 33 mph, which will add stress for anyone working or playing outside and can toss around unsecured outdoor items. Overnight lows are forecast to stay stuck in the upper 70s, an unusually warm setup that could bring near-record minimum temperatures in some spots, according to the National Weather Service.
Cooling Options And Safety
Air conditioning is about to become everyone’s best friend. Libraries, community centers and other public buildings are expected to be popular cooling spots this afternoon and evening. The City of Oklahoma City maintains a page with heat resources and information on local cooling locations. Check in on neighbors, older adults and pets, since they tend to feel the heat first, and consider pushing strenuous outdoor chores to the early morning or later in the evening. When you are outside, bring water, wear light clothing and take frequent breaks.
What To Expect This Week
The heat is not going anywhere fast. Through the week, highs are expected to stay in the mid- to upper-90s, with readings edging toward the 99–101°F range by late week while rain chances stay minimal. Warm overnight lows will cut into the usual nighttime cooldown for many neighborhoods. Keep an eye on updated local forecasts in case additional watches or advisories are issued.
Quick Safety Tips
Drink plenty of fluids, avoid heavy exertion during the hottest part of the day and never leave children or pets in parked cars, even for a short time. If someone shows signs such as dizziness, confusion, fainting or an extremely high body temperature, seek immediate medical help or call 911. Employers and event organizers should adjust schedules or activities when possible to reduce outdoor exposure during advisory hours.
