Washington, D.C. – A dangerous stretch of heat begins Saturday in the nation’s capital, with temperatures nearing 98°F and heat indexes soaring to 104°F. Residents, tourists, and especially commuters along I-395 and across the National Mall should prepare for prolonged exposure risks and take precautions to stay cool.
According to the National Weather Service, Saturday will be mostly sunny with light winds and a high near 93°F before spiking to 98°F Sunday. Monday and Tuesday will each bring highs of 100°F. The NWS advises limiting outdoor activity between noon and 5 p.m., staying hydrated, and checking on vulnerable individuals.
Expect clear skies and warm nights, with lows staying in the mid-to-upper 70s. Southwest winds will remain light, offering little relief. The elevated heat index will increase the risk of heat exhaustion and heat stroke for those without air conditioning or adequate hydration.
Cooling strategies should include early morning errands, using Metro instead of walking where possible, and wearing lightweight, breathable clothing. Pepco customers are also urged to monitor usage, as power demand could surge through early next week.
Isolated thunderstorms could return Thursday into Friday, offering some relief. Until then, conditions will remain dangerously hot across the District.
