Washington woke up to clear skies and crisp, mild air on Friday, May 29, with Reagan National Airport (KDCA) reporting about 57°F early in the morning. By this afternoon, temperatures are expected to climb into the upper 70s, setting up a very easygoing end to the workweek.

Sunny Skies, Gentle Northwest Breeze

Friday is shaping up as one of those gold-star D.C. days, with plenty of sun and a high near 79°F. A light northwest breeze around 3 to 8 mph will keep things comfortable without turning it into a hat-chasing situation. Visibility should stay strong and rain chances are essentially zero, so outdoor plans and patio dinners are in the clear.

Weekend Cools Down And Kicks Up The Wind

A dry cold front moves in on Saturday, trimming daytime highs to about 73°F and shifting winds to the north at 9 to 14 mph, with gusts that could reach 23 mph in the afternoon and evening. Saturday night turns noticeably cooler, with lows near 52°F, and forecasters note that some higher-elevation valleys well northwest of the city could see patchy frost overnight.

The Small Craft Advisory that covered lower Chesapeake waters early Friday expired at 4 a.m. on May 29, but additional advisories are possible behind the front on Saturday, according to the National Weather Service.

How To Play The Forecast

Today and Sunday both look comfortable for outdoor events, so this is solid timing for markets, park hangs, and backyard gatherings. Sunscreen will still earn its keep, and a light layer will help with the cooler morning starts.

If your plans fall on Saturday afternoon or evening, be ready for the uptick in wind. Secure tents, banners, and any lightweight setups, and expect choppier conditions on the Potomac and the Bay as those northwest gusts arrive. The good news is that conditions stay dry through early next week, with temperatures gradually sliding back toward seasonal norms.
