Boston eased into Saturday, July 25, 2026 with a cool, humid start that will give way to a comfortably bright afternoon. Sunshine sticks around later in the day, with a high near 79°F and a light southerly breeze of 0–12 mph keeping things pleasant across the city. If you are trying to pick the better weekend day for outdoor plans, this is the one to circle.
Inland neighborhoods will run a bit warmer, topping out in the low to mid 80s, while the immediate coastline hangs in the mid-to-upper 70s thanks to an onshore breeze. Tonight stays mostly clear with a low around 61°F. Forecasts and the office discussion point to mainly dry weather through the weekend, with increasing chances of showers and thunderstorms Tuesday and Wednesday. No watches or warnings are posted this morning, according to the National Weather Service.
Rip Currents and Beach Plans
That same onshore flow that keeps the shoreline cooler today will help kick up the surf and boost the risk of rip currents on Sunday, especially at east-facing beaches on the Cape and islands. If you are heading into the water, lifeguarded beaches are the safest bet, and the usual rip-current rules still apply: do not try to swim straight against the current, move parallel to the shore until you are out of it, and signal for help if you cannot get free. Those precautions are recommended by the United States Lifesaving Association.
What To Expect This Week
Looking ahead, forecasters expect a midlevel trough to send periodic shortwaves across the region from late Monday into midweek, making Tuesday, July 28, and Wednesday, July 29, the most likely days for scattered showers and thunderstorms. With deeper moisture in place, any storms that do form could drop brief heavy downpours and trigger localized flash flooding in poor-drainage spots, mainly during the afternoon and evening hours. Out on the water, seas of 1–4 ft today are expected to build as marine conditions gradually trend rougher, although no marine advisories are in effect right now.
The takeaway: enjoy today’s sunshine, then keep an eye on conditions before you hit the beach Sunday or commit to outdoor events later in the week. Forecasters will update the outlook if the midweek pattern sharpens and the storm threat changes. In the meantime, plan on sunscreen, plenty of water, and a backup option for any gatherings scheduled for Tuesday or Wednesday.
