What January feels like
January is high season twice over — winter escapees and humpback season, which peaks in the Auau Channel between Maui and Lanai. Expect a shower to pass over Kahului while Kihei sits in full sun; the island splits its weather that finely.
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 77° — comfortable for swimming.
