Boston started Monday on a crisp but bright note, with clear skies, temperatures near 45°F at Logan Airport, and early sunshine already cutting through the morning chill. The city can expect a dry, sunny day with a high around 57°F today (Monday, April 27, 2026) and light northeast winds. If you have outdoor errands, a lunchtime patio, or a quick walk along the Greenway in mind, this is one of the better windows of the week. Just keep a light jacket handy if you are headed to the waterfront, since sea breezes will keep shore neighborhoods noticeably cooler.
Afternoon Seabreezes Keep The Coast Cool
As the day wears on, sea breezes will kick in and keep Cape Cod and Boston Harbor neighborhoods stuck in the low to mid 50s, while inland communities climb a few degrees warmer. Winds stay generally light for most, but gusts near the Cape and Islands may reach the high 20s mph later in the day. If you are bouncing between downtown and the shoreline, dressing in layers could be the difference between pleasant and downright chilly.
Midweek Turn Toward Rainy Weather
Tuesday, April 28, 2026, looks similar but a touch cooler, with a high near 50°F and some increase in clouds along the immediate coast Tuesday night. Showers are still unlikely through Wednesday, but forecasters expect the pattern to turn wetter late Wednesday night into Thursday, April 30, 2026. A frontal occlusion and a possible secondary low should bring a soaking rain and the best chance for steady, widespread precipitation.
Forecasters at the National Weather Service Boston/Norton also note that small craft advisories are posted for portions of the eastern and southern waters as seas build. Boaters should check the NWS marine product descriptions for specific advisory details.
Marine Outlook
Seas are expected to rise to around 6 feet by Tuesday night, making conditions choppy and hazardous for small vessels. Offshore trips are not a great idea while advisories are in effect, and even local harbors can see some stronger gusts near shore. If you plan to head out on the water, file a float plan and check the latest marine forecast right before you leave the dock.
Plan Ahead
Use Monday and Tuesday’s sunshine and dry roads for outdoor plans and errands, but do not retire the umbrella just yet. Wednesday night into Thursday is the period to watch for a solid stretch of steady rain and gusty winds. If you have coastal plans, commuting concerns, or boating scheduled, keep an eye on updated forecasts, since conditions can change quickly as the frontal system moves in.
