Traveller notes on Nantucket in April
Notes from nearby Boston (144 km away)
Nantucket doesn't have its own notes for April yet — these are about Boston, close enough to share the season.
Locals refuse to give April a number, and they're right to. "April is a huge transition month here and it could be snowing or 85°F." Another puts the range at "the 40s or the 90s, sunny or cloudy or rain, but not usually snow" — the two posters don't even agree on whether snow is on the table, which is itself the answer. The practical advice that follows is unusually specific: "if you come on April 12th, don't pack until you check the weather on April 11th. Really." Layers, a rain jacket, a hood or hat, and warm things underneath. Our record gives April 13.4°C days and 4.7°C nights with 1.9cm of snow still on the books, plus 22.6 kph average wind — but an average is exactly the wrong tool for this month, and the forum knows it.
Other months in Nantucket
Nantucket's forum rates July for warm, sunny days, with one recurring caveat worth knowing before booking a beach-heavy trip: the ocean itself stays genuinely chilly until August catches up, so swimming is more bracing than the air temperature would suggest. Regulars who want both warm water and warm air tend to point toward September instead.
