What January feels like
January is one of the drier months here, which still means an umbrella lives in the car. Mauna Kea usually has snow on it, and on a clear morning you can look up at it from Bayfront while standing in a T-shirt.
Rain arrives about 10 days of the month, so keep one flexible day in your plans. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 78° — bath-warm.
