The region is already stepping outside into a wall of steam at Reagan National this morning, with temperatures around 73°F and dew points in the low 70s. Washington, D.C. is under a Heat Advisory today, running from 11 a.m. to 8 p.m. on Thursday, June 11. Forecast highs near 95°F and heat-index values around 105°F will make midday and afternoon outdoor time a real health risk for vulnerable residents.

Afternoon Heat And Scattered Storms

The National Weather Service is calling for a fast warm-up through midday, with highs around 95°F and a peak heat index near 105°F. After about 4 p.m., isolated showers and thunderstorms could pop up, bringing brief heavy downpours and gusty winds. Forecasters also flag Friday, June 12, 2026, as likely hotter still, with highs near 97°F and a higher chance of afternoon storms, so anyone planning outdoor work should adjust schedules where possible.

Where To Cool Off

The D.C. Department of Human Services is urging residents without air conditioning to use public cooling centers, indoor pools, and senior wellness centers during heat alerts; locations are listed on the District’s heat map or available by calling 311. The city also provides transportation and shelter options for people experiencing homelessness; contact the D.C. Department of Human Services for details. Officials also remind neighbors to check in on older adults and anyone working outside, and to never leave children or pets in parked vehicles.

Commute And Outdoor Tips

Expect a sticky, sluggish afternoon commute, and try to shift strenuous exercise or yard work to early morning or later in the evening while drinking plenty of water. If you will be out on the Potomac or other open water, keep an eye on forecast updates, since gusty winds and choppy conditions are possible this weekend. Keep phones charged and have a plan to get indoors quickly if you or someone nearby starts to show signs of heat illness.
