Washington, D.C. is starting this Tuesday on a relatively calm note, with partly cloudy skies and temperatures near 62°F at Reagan National Airport, but the cool feel will not last long. Forecasters expect a quick warm-up, with highs around 89°F this afternoon and low 90s by midweek, making the afternoon hours the roughest stretch for outdoor plans. It is a good day to keep water handy, shift strenuous activity away from the late-morning to early-evening window, and be ready for some gusty air.
Afternoon Winds And Boating Conditions
Southwest winds are expected to ramp up this afternoon, with sustained speeds in the single digits to mid-teens and gusts on land reaching into the mid-20s. Over open water, gusts will run higher and the surface will turn choppy. A Small Craft Advisory is in effect for the tidal Potomac and nearby Chesapeake waters this afternoon into the evening, so boaters should expect rougher rides and make sure loose gear at marinas is tied down. Forecasters also note that the combination of gusty winds and dry air will increase the region’s fire-weather threat midweek, with Fire Weather Watches possible for Wednesday and Thursday, according to the National Weather Service.
Record Heat Through Thursday
An upper-level ridge will keep the area hot and mostly dry through Thursday, with the most likely windows for low 90s on Wednesday, April 15, 2026, and Thursday, April 16, 2026. Several daily records could be tied or broken during that stretch. Overnight lows are expected to stay quite warm, so many neighborhoods will not see much relief from the heat even after sunset. That pattern makes this week especially uncomfortable for outdoor workers, pets, and anyone without reliable air conditioning.
Cooling Centers And Safety
The District activates its Heat Emergency Plan when the temperature or heat index reaches 95°F, which triggers the opening of cooling centers and transportation assistance. Residents can call 311 or the shelter hotline at (202) 399-7093 for help when that threshold is met. Until then, officials recommend staying hydrated, avoiding midday exertion, checking on neighbors, and never leaving children or pets in vehicles. See the District Heat Emergency Plan for locations and details.
