Friday, May 29, 2026 — Boston rolled out of bed under mostly cloudy skies and a cool 57°F at Logan this morning, and the city will stay on the chilly side today. Expect a mostly dry, seasonably cool Friday with a high near 65°F before a late-day uptick in shower chances. The real shakeup arrives Saturday, when a passing low pressure system drags in widespread rain, blustery north winds, and drops daytime temperatures into the upper 40s.
Late-Day Showers And Night Rain
Spotty showers could start to pop after about 4 p.m. Friday, with a better shot at steady rain overnight into Saturday. Lows tonight dip to around 46°F, and forecasters say many spots could pick up roughly a quarter to a half-inch of rain by the time the system moves through. According to NWS Boston, some interior high elevations could even mix in a few wet flakes in the coldest pockets Saturday morning.
Weekend Travel And MBTA Work
Anyone riding the T this weekend will be juggling both the soggy forecast and planned service changes. Red Line branch suspensions and Green Line changes are scheduled May 29-31, which could make alternative routes trickier if ferry or shuttle services end up slowed by strong winds. Travelers are urged to check local transit advisories before heading out. The city has the May service changes and closures posted on the City of Boston website.
Strong Gusts Saturday And Rough Seas
A Wind Advisory is in effect for parts of eastern Massachusetts on Saturday, May 30, from about 10 a.m. to 8 p.m. North winds are expected to run 15-25 mph, with gusts up to 45 mph possible along the coast, while inland areas still see a blustery but slightly less intense setup. Offshore, a Gale Warning is posted, with seas building to roughly 8-12 feet and posing a risk to small craft and ferries. For official timing and updates, see NWS Boston.
Residents would be wise to tie down loose outdoor furniture and trash cans tonight, and to delay nonessential ferry trips Saturday morning if they can. Build in extra time for weekend errands, keep high-profile vehicles on the cautious side during the windiest stretch, and expect that any outdoor plans Saturday will be dealing with a wet, gusty mess for much of the day.
