How busy is Boston in October?

The busiest days are the 3rd, 5th, 12th and 26th, and 27 more.

Ships call on 18 of 31 days, a typical call day carrying at least 2,678 guests between them — real, but a secondary part of the crowd here; the season moves the needle more.

The month is not one thing: its lightest day sits at 67% of the year and its heaviest at 100%, so where you land inside it matters. Daylight runs about 11 hours.

Either side of it, September is about half as busy and November is far calmer.

The lightest days are the 1st, 2nd and 4th. Still busy — but the easiest of the month — 13 days share that level, so there is room to choose.

Is October worth it in Boston?

Heavy crowds and only poor weather to show for it — a poor trade. For better value, come in September or June.

Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
