What December feels like
The Honolulu Marathon takes over the second Sunday and the whole waterfront with it. Christmas through New Year's is the most expensive week of the year here, and the Pipeline crowd up north makes it a two-event month for anyone who follows surfing.
Expect about 3 days with real rain — enough to notice, not enough to plan around. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 78° — bath-warm.
