Boston woke up under clear skies on Tuesday, April 28, 2026, with temperatures sitting in the mid-40s. Sunshine is expected to hold through the afternoon with a high near 54°F, although a steady northeast breeze will keep the immediate coast a few degrees cooler.
Afternoon Conditions
Most neighborhoods should stay bright and dry through the afternoon. Inland spots will run a bit warmer, while harbor-facing areas hang in the upper 40s to lower 50s. Northeast winds will run about 5 to 10 mph, and the breeze will feel stronger along the waterfront.
Wednesday Night Into Thursday
Clouds increase on Wednesday, with a chance of spotty showers by the afternoon, especially near the coast. The bigger issue arrives later in the week. Rain chances ramp up Wednesday night into Thursday morning, with a more widespread soaking expected Thursday. Many locations may pick up around three-quarters of an inch of rain, with localized amounts near an inch and a few thunderstorms possible.
According to the National Weather Service, outer waters are under a Small Craft Advisory through 8 AM Thursday, April 30. For some context on how this pattern evolved, see our coverage of the soggy Wednesday after frosty wake-up.
Boaters And Commuters
Outer waters will stay choppy, with seas around 3 to 6 feet, so small-craft operators and ferry riders should be ready for a rough ride through Thursday morning. The Thursday morning commute could be slowed by steady rain and pockets of reduced visibility, so bring an umbrella and allow extra travel time.
Weekend Outlook
The pattern turns cooler and unsettled into the weekend as a slow upper-level trough lingers over New England, keeping scattered showers in play and highs mainly in the 50s. There could be a rebound to the upper 50s by Monday, but plan on on-and-off light rain through the period.
