What March feels like
March is the tail of whale season and the start of spring-break flights. The manta ray night dive off Keauhou runs all year, and this is the month you can still get a spot on a boat without a scramble.
Real rain shows up about 2 days all month; the rest stay dry.
Can you swim?
The ocean runs about 78° — bath-warm.
