Friday morning, May 15, 2026, Baltimore rolled out of bed to a crisp start in the low 50s, mostly sunny and feeling more like early spring than late May. Do not get too attached to the jacket weather, though. By afternoon, the sun takes over and temperatures climb toward a high near 72°F, with a dry northwest breeze making it feel even more comfortable.
Afternoon Winds Pick Up
Through the afternoon, northwest winds are expected around 8 to 12 mph, with gusts reaching into the low 20s. The stiffest breeze should show up near the Inner Harbor and on exposed bridges, then ease toward late afternoon. Those gusts might shuffle around lightweight patio furniture and make a walk on the waterfront or a bike ride feel a bit more like a workout. Marine traffic could feel it too, with the National Weather Service keeping marine advisories in place for local waters through mid-afternoon.
Weekend And Early Week Heat
By Saturday, the cooler air is history. Skies stay sunny with a high near 84°F, then Sunday jumps to about 89°F with a slight chance of an afternoon shower or an isolated thunderstorm after 2 p.m. Early next week turns up the heat even more, with Monday and Tuesday potentially pushing into the low 90s as humidity rises. Forecasters say heat headlines are possible by midweek as a warmer pattern settles over the region. If you are planning outdoor events, the morning hours will be your best bet for anything that involves moving around. The National Weather Service notes that highs in the low 90s are on the table early next week.
How To Prepare
With a quick flip from cool to hot, it is a good time to start thinking summer rules again. Try to schedule strenuous outdoor activity in the morning, drink plenty of water, and check on older neighbors and anyone without air conditioning. Baltimore's Mayor's Office of Homeless Services keeps a Code Red plan and a list of cooling centers that open during extreme heat. For up-to-date locations and hours, residents can call 311. Details are outlined in the Mayor's Office of Homeless Services Code Red plan.
