What to pack

What April feels like

April is the reopening month — shutters come off, the Rail Trail fills with cyclists, and Patriots' Day weekend is the unofficial start of the season. The water is still wetsuit-only, and the number of damp days is higher than anyone expects of spring.

Rain arrives about 7 days of the month, so keep one flexible day in your plans. about 7 nights dip below freezing.

Can you swim?

The ocean runs about 49° — frigid — locals in wetsuits only.
