Boston is starting Tuesday, October 27, with a chilly, bright setup: temperatures are in the upper 40s early, skies are clear, and the city is headed for a high near 53. The bigger story is the swing ahead, with a quick warm-up sending temperatures into the upper 60s and low 70s before Halloween.
Tuesday Stays Sunny But Feels Like Fall
Expect a dry afternoon with N/NNE winds of 7 to 14 knots and no rain in the forecast. Urban and coastal areas, including Boston, are forecast to have lows in the 30s Tuesday night under mostly clear skies, while the National Weather Service says the early-week pattern will remain dry even as overnight cold becomes more noticeable.
Warmth Arrives Before The Weekend
Wednesday brings another mostly sunny day with a high near 56, followed by Thursday's high in the mid-60s. Friday looks like the warmest day of the stretch, with sunshine, a high near 71 and west winds around 12 mph—an unusually friendly forecast for late October.
The latest outlook is a meaningful refresh from the earlier Hoodline forecast, which already had Boston trending cooler Tuesday before a late-week rebound. The updated version gives Friday a stronger warm-up and keeps Saturday, October 31, mostly sunny, so Halloween plans should not need a weather-related plot twist.
Halloween Looks Mostly Sunny
Saturday should reach around 60 with mostly sunny skies and gusty northwest winds. Saturday night turns partly cloudy with a low near 51, then Sunday stays mild at about 62 with partly sunny skies; periodic showers are possible later in the weekend and next week, though timing remains uncertain.
The pattern may become unsettled early next week, with periodic shower chances. There are no land watches or warnings in the forecast, though a Small Craft Advisory remains in effect through 2 p.m. Tuesday for some eastern and southeastern waters, so boaters should use caution even if the city streets look inviting.
