Boston woke up to mild, muggy air on Wednesday, May 6, 2026, with temperatures around 59°F under mostly cloudy skies. South-southwest winds are already on the breezy side this morning and are expected to pick up through the afternoon ahead of a cold front. For most neighborhoods, that sets the stage for a wet, windy ride home once the late-day showers show up.
Afternoon Showers And Gusty Southwest Wind
Rain showers are likely this afternoon, mainly after 3 p.m. on Wednesday, May 6, 2026, with the highest chances lining up with the late afternoon and evening commute. South winds of 16 to 20 mph are in the cards, with gusts reaching into the 20 to 30 mph range, especially along the waterfront, which could make both driving and ferry trips feel pretty blustery. Most spots should only pick up light rainfall totals under a tenth of an inch, although a brief heavier downpour or an embedded thunderstorm could squeeze out locally higher amounts, according to the National Weather Service Boston/Norton.
Tonight Into Thursday
Showers stick around into Wednesday night with lows near 53°F, and some neighborhoods could tack on a few additional tenths of an inch of rain overnight. The cold front is expected to slide offshore by Thursday morning, letting in drier air and allowing for partial clearing by the afternoon, with highs in the low 60s.

Marine And Commute Impacts
Small Craft Advisories are posted for many coastal zones through Wednesday night into Thursday, so mariners and ferry riders should plan on choppy seas and gusty winds. Drivers can expect wet roads and occasionally strong crosswinds during the evening commute, so securing loose outdoor items and building in a little extra travel time is a smart move. If you have on-the-water plans, check with ferry operators or the latest forecasts before heading out.
