What April feels like
April is when the dry season announces itself, and it is also Golden Week — the run of Japanese holidays at the end of the month that fills Waikiki hotels. Merrie Monarch happens over on the Big Island, and a fair share of Honolulu flies across for it.
Real rain shows up about 2 days all month; the rest stay dry. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 78° — bath-warm.
