What May feels like
May is quiet on this coast — the whale boats have switched to snorkel trips and the summer rates haven't kicked in. When the coffee trees flower, the whole belt above town smells like jasmine for a week and turns white; locals call it Kona snow.
Real rain shows up about 2 days all month; the rest stay dry.
Can you swim?
The ocean runs about 80° — bath-warm.
