Boston woke up to crystal-clear skies on Wednesday, March 18, with temperatures at Logan hovering near 27°F and a brisk early breeze to remind everyone it is still March in New England. Daytime highs are only expected to claw their way into the mid-30s, so it will be a sunny but cool afternoon around the city.
Today and Tonight
Sunshine sticks around through the afternoon with a high near 36°F and southwest winds around 5 to 12 mph. Skies turn partly cloudy this evening, and temperatures slide back to a low near 30°F overnight.
On Thursday, readings nudge up into the upper 30s to around 40°F, and a more noticeable warm-up arrives Friday, with highs heading for the low 50s. According to the National Weather Service, rain chances start to climb late Friday night and continue into the weekend.
Weekend Outlook
Saturday and Sunday bring periodic chances for showers as milder air moves in, with highs currently projected in the upper 40s to mid-50s. Forecast confidence drops a bit on the exact timing of each batch of rain, so it is wise to keep outdoor plans flexible and have a backup option indoors. This early-week warmup and pattern shift were already on the radar in Boston pops into the 60s.
Boaters and Waterfronts
Small Craft Advisories are up for many bay and coastal waters this morning, and the outer waters may stay choppy into tonight and Thursday as seas slowly subside. Mariners are urged to check zone-specific forecasts and postpone nonessential trips until conditions ease. For the latest marine advisories, see the National Weather Service.
Commute and Tips
Roads should be dry and the morning commute largely routine, with no major weather-related hiccups expected. The chill, however, is very real, so dress in layers if you are out early. By late afternoon, a seabreeze could knock a few degrees off temperatures in waterfront neighborhoods. If you depend on ferries or water taxis, keep an eye on service alerts just in case the marine conditions cause any tweaks to the schedule.
