Boston is waking up under a blanket of patchy fog this Wednesday, July 22, 2026, but it will thin out by late morning. Skies turn partly sunny with a high near 85°F, and while most neighborhoods stay dry, a few isolated showers or thunderstorms could fire up mid-to-late afternoon. Any storm that pops could feature brief heavy downpours and locally damaging wind gusts.
Foggy Morning, Clearing By Midday
Low clouds and localized fog will lift from inland neighborhoods toward the harbor by late morning as southwest winds of about 10 to 15 mph usher in drier air. Temperatures start in the low to mid 70s and climb into the low to mid 80s away from the water, while the waterfront and Cape areas hold a few degrees cooler.
Afternoon Storm Risk
A weak front sliding through late in the day could trigger a few scattered storms between roughly 3 p.m. and 6 p.m. Coverage looks spotty, so many locations will miss the rain entirely. Any storm that does develop may drop heavy rain and kick up gusty winds that briefly cut visibility and leave roads slick, so keep an eye on radar if you have outdoor plans later today.
Coastal Hazards And Boaters
Small Craft Advisories remain posted for much of the coastal waters, and a High Surf Advisory is in place for south-facing beaches through Thursday evening. Southerly winds of around 10 to 20 knots, with gusts up to 25 to 30 knots, will push up seas on the outer waters. Boaters and beachgoers should steer clear of exposed surf and follow guidance from the National Weather Service.
Thursday Through The Weekend
High pressure settles in behind the front, bringing a stretch of drier, seasonable weather from Thursday through the weekend. Expect highs mostly in the upper 70s to near 80°F with plenty of sunshine. Rain chances dip until early next week, when a more unsettled pattern returns and spotty showers become possible again.
Plan For Your Commute
Build in some extra time for the morning drive, since early fog can slow things down. Isolated afternoon storms could also cause short, sharp delays during the ride home. Red Line service between Alewife and Park Street is suspended through July 30 for planned work, so expect shuttle buses and check local transit alerts on Cambridge.gov.
Quick Tips
Grab a light rain jacket and keep a radar app handy in case one of those afternoon cells drifts over your neighborhood. If you are heading to the beach, pay attention to posted flags and stay out of the water while advisories are active.
