Boston woke up Thursday, July 23, 2026, under mostly cloudy skies and around 64°F at Logan, but the gray start will not last. Clouds are expected to peel back for a sunny, comfortably warm afternoon with a high near 80°F. Light north winds and lower humidity should make it a good day for lunch outside in most neighborhoods, though a developing sea breeze will keep the immediate shoreline a bit cooler.
Afternoon Sun And Sea Breezes
Forecasters are calling for full sun this afternoon with highs near 80°F across the city and north winds around 5 to 10 mph. Overnight, temperatures should slip into the low 60s. Patchy fog is possible early this morning on Cape Cod and the Islands, but it is expected to burn off by midmorning, according to the National Weather Service.
High Surf Advisory For South-Facing Beaches
A High Surf Advisory remains in effect through 8 PM EDT Thursday for ocean-exposed south-facing beaches of the Cape and parts of southern Rhode Island, with elevated surf and dangerous rip currents expected. Surf heights in the advisory area are forecast around 5 to 7 feet, so swimmers should stick close to lifeguards and avoid jetties and rocks. See the official marine statement for details from the National Weather Service.
Boaters And Beachgoers Should Take Caution
Small craft advisories are posted for parts of the coastal waters into the afternoon and tonight, with choppy seas of around 5 to 6 feet making small-boat operations hazardous. Local mariners should consider returning to port early, and swimmers should heed posted warnings and lifeguard instructions. For zone-specific timing and marine details, check the National Weather Service.
Unsettled Weather Returns Next Week
The pattern turns more unsettled early to mid-week next week, with increased chances for scattered showers and thunderstorms on Tuesday, July 28, and Wednesday, July 29, and some storms could be heavy. If you have outdoor plans later in the week, monitor updated forecasts from the National Weather Service.
