What to pack

What May feels like

Lei Day is May 1 and the whole city takes it seriously — school pageants, the big lei contest at Kapiolani Park, everyone wearing flowers to work. The south-shore surf starts filling in about now, which is why the town breaks off Waikiki get busy while the North Shore goes quiet.

Real rain shows up about 2 days all month; the rest stay dry. It’s sticky — light fabrics and an afternoon break earn their keep.

Can you swim?

The ocean runs about 78° — bath-warm.
