Friday, June 19, 2026, Juneteenth, started mostly clear across Boston, with Logan reporting about 66°F this morning. Today will stay sunny and pleasant with a high near 78°F, although a brisk west wind will take the edge off along the harbor and shoreline. Outdoor gatherings, parades, and cookouts should be in good shape, but do expect gusty moments that can tug at tents and light decorations.
Afternoon Winds Pick Up
West winds of roughly 14 to 17 mph, with gusts up to about 30 mph, are expected this afternoon, with the strongest blasts along the waterfront and exposed hills. Small craft advisories and gale warnings are in effect for parts of the coastal waters, so mariners should avoid nonessential trips and secure loose gear, and ferry riders should be ready for a choppy ride, according to the National Weather Service Boston/Norton. For background on the coastal impacts, see our earlier forecast.
Weekend And Early-Week Outlook
Dry, lower-humidity air holds through Saturday with highs in the mid-70s and mostly sunny skies, giving the city a comfortable weekend window for outdoor plans. Sunday carries a small risk of afternoon showers or isolated thunderstorms, while a stronger system is set to bring steadier rain Monday into Tuesday, a stretch that could produce heavier totals and breezy conditions that slow commutes. Keep plans flexible for early next week and check updated forecasts if you have outdoor or travel plans on Monday and Tuesday.
Tips For Today
Tie down or bring inside lightweight outdoor furniture and decorations, and consider moving fragile Juneteenth displays away from the most exposed waterfront spots. Boaters should delay nonessential trips and check with operators, and pedestrians and cyclists along exposed bridges and paths should be ready for sudden gusts. For the latest watches and advisories, check National Weather Service updates and local operators before heading out.
