What April feels like
April is when the Kalalau Trail dries enough to be sensible, though it never really dries — plan on mud, and book Haena State Park entry ahead because the park caps the cars. The east side loses its winter swell about now.
Expect about 5 days with real rain — enough to notice, not enough to plan around. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 80° — bath-warm.
