What January feels like
January is the heart of the north-shore surf season — Hanalei Bay goes from swimming pool to closed-out in a day, and the county shuts beaches when it does. Whales work the south and east coasts, and the roosters are exactly as loud as they are the rest of the year.
Expect about 4 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 80° — bath-warm.
