What March feels like
March on the Cape is all wind and washed-up wrack line, and the sea is still colder than the air — you feel it the moment you step onto the sand. A few places quietly reopen for the last weekends of the month, testing the water in every sense.
Expect about 11 days with something falling — rain, snow, or the sloppy mix in between. about 19 nights dip below freezing.
Can you swim?
The ocean runs about 42° — frigid — locals in wetsuits only.
