What to expect

Daytime

Cool days in Boston: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.

Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.

Rain

October is a wetter month in Boston. Showers are part of the deal, not a spoiled surprise.

Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.

Evening

Evenings are cooler. A layer helps after sunset.

What to pack

  • Rain jacket

  • A layer for cooler evenings
