Boston to Montreal cruise first week of June...

what kind of clothes to bring? I know it won't be shorts and tee shirt weather-- do we need jeans? Layers? We're on the maasdam, if that matters... thanks for some direction

Expect chilly at night on deck (50s) and up into 80s during the day. Can hit 90 anytime in the summer, too.

I've done that cruise once in July, once in August and once in early May. There was ice on the deck in early May and it was nice every day in July and August. I suspect June will be somewhere in between. I'd bring layers (always a good idea). It did rain on us in Quebec in August, so an umbrella and wind breaker are a good idea.
