Boston rolled into Sunday, June 7, 2026, under bright skies and comfortable morning temperatures, but the calm vibe will not last all day. A mostly sunny start will push afternoon highs to around 79°F, then scattered showers and isolated thunderstorms are expected to pop up after 2 p.m. West winds around 15 mph, with gusts up to 25 mph, could turn any brief downpours into wind-driven soakings that take the shine off outdoor plans.
Afternoon Showers And Gusty Winds
By Sunday afternoon, there is a 50% chance of showers and thunderstorms across Boston and eastern Massachusetts. Most of what moves through should be on the showery side, but a few stronger cells could deliver locally heavy downpours and even small hail. The gusty winds will keep conditions feeling breezy, and temperatures are expected to slide back into the low 70s by early evening, according to the National Weather Service Boston/Norton.
Tonight Into Monday
Rain showers are likely Sunday night before 11 p.m., with temperatures dipping to around 56°F. North winds of 9 to 14 mph could gust to roughly 25 mph, keeping it feeling cool and unsettled for a time. Showers should taper off overnight, setting up a drier and seasonable Monday with sunshine and a high near 72°F. Inland areas may cool down a bit more than the city, so a light jacket is a smart move for Monday morning.
Marine And Commute Impacts
A Small Craft Advisory remains in effect for the southern coastal waters through 8 a.m. Monday, which means choppy seas and gusty northerly winds on the harbor. Boaters will want to take it seriously. For anyone with evening plans on land, allow extra travel time, since brief heavy rain can slow traffic and leave bridge decks slick. MBTA riders should keep an eye on MBTA alerts for real-time service updates before heading out.
Looking Ahead
After the cooler, drier start to the week, the pattern flips quickly. By Tuesday, temperatures are expected to jump into the mid-80s, with humidity on the rise later in the week. Another front may trigger a fresh round of showers and thunderstorms by Thursday, so anyone banking on flawless outdoor weather later in the week will want to stay tuned for updates.
