After an ideal summer weekend for wandering outdoors, forecasts for the D.C. region this week see temperatures climbing upward, with heat indexes possibly breaking 100 degrees.
The new word on the street is calling it a heat wave. Stay inside — and stay cool. Here’s what you need to know.
Starting Monday, an extended run of 90-degree days begins, with humidity levels and the dew point increasing from Tuesday onward. The region may experience increasing heat indexes of over 100 degrees through the week and upcoming weekend.
“We’re heading into a heat wave, and some days will be more intense than others, particularly in the back half of the week,” 7News First Alert Meteorologist Brian van de Graaff said.
With humidity expected to remain high in the overnights, don’t expect too much relief after dark. Plan your days and pace yourself accordingly, with plenty of fluids and cool shelter during the day.
D.C. is operating under an Extended Heat Emergency plan, in place Monday through Friday because of the hot weather. This designation activates cooling centers in the area for residents who need them.

The District’s spray parks and pools are open for locals to cool off on these hot days.
While the skies are expected to remain sunny with few clouds, the National Weather Service is preparing for heat to peak near Friday night, with current forecasts nearing 97 degrees for the high and 75 degrees for the low.
The District is encouraging locals to stay indoors over the next few days if possible, check on neighbors — particularly those who are especially vulnerable to the heat, including elderly people, young children and those with disabilities — and wear loose, lightweight clothing.
Pets should be kept indoors, given plenty of water and walked early in the morning ahead of peak temperatures. For animal emergencies, including animals left outside or in cars in the heat, call the Humane Rescue Alliance at (202) 723-5730.
“Remember your heat safety tips: hydrate, take plenty of breaks in the shade if you must be outside,” said 7News First Alert meteorologist Mark Peña. “Otherwise, avoid strenuous outdoor activity during the afternoon and apply and reapply sunscreen.”
Symptoms of heat stroke and heat exhaustion include throbbing headaches, chills, disorientation and dry, red skin. Be aware of these signs, and call 911 if you or someone you know might be experiencing a heat-related illness.
Free transportation to cooling centers is available. To make arrangements for yourself or someone you know, call the shelter hotline at (202) 399-7093 or dial 311.
