What January feels like
January is when the North Shore takes over the island's attention — if the Eddie gets called at Waimea, half of Oahu drives up the H-2 and the town side empties out. Humpbacks are back in the channels, and the rain that does fall tends to come through overnight.
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 77° — comfortable for swimming.
