What March feels like
Late March is when the Grand Strand flips the switch — Broadway at the Beach comes back to life and the first out-of-state plates show up on Kings Highway. Early in the month is still quiet and cheap, which is the smart booking if you don't need the ocean.
Expect about 6 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 59° — cold — a quick dip takes resolve.
