Baltimore starts the week on a springlike high note, Monday, March 9, 2026, waking up to bright sunshine, morning temperatures in the upper 40s, and an afternoon high near 70°F. Light southwest winds and clear skies should make for a near-record, pleasantly mild day, offering a short window for outdoor plans and errands before the weather turns sharply cooler and wetter by midweek.
Monday–Tuesday: Springlike Sunshine
Monday and Tuesday are set to deliver the most comfortable stretch of the week, with sunny, dry conditions and low humidity. Highs should reach around 70°F on Monday and roughly 71°F on Tuesday, with light breezes keeping things feeling comfortably mild rather than muggy. If you have yard work, a run, or a long walk on your to-do list, these are the days to circle.

Midweek Front Brings Rain And Gusts
A strong cold front is expected to sweep through late Wednesday, March 11, into Thursday, March 12, flipping the script from warm and calm to cooler, wetter, and windier. There is a chance of showers and thunderstorms on Wednesday, with rain likely from Wednesday night into Thursday.
According to the National Weather Service, gusts could reach roughly 25 to 40 mph, especially over open water, and temperatures may drop 20 to 30°F behind the front. Before that cooler air spills in, highs on Wednesday are expected to top out near 75°F. In higher elevation areas, a brief rain-and-snow mix is possible Thursday night as colder air deepens.
On The Water, Commute And Plans
Conditions on the water will deteriorate as the front approaches, with rougher weather expected from Wednesday into Thursday. Small boats may want to stay in port as winds pick up, and ferry operations and bridge crossings could also be affected.
For commuters, Wednesday night looks to bring a wetter, windier ride. It is a good idea to secure loose outdoor items ahead of time and allow extra time for both road and transit travel. As of Monday morning, there are no active watches or warnings for Baltimore, but conditions are expected to change quickly later in the week, so keep an eye on official forecasts and check with your transit agency before heading out.
