We are trying to plan a trip to Maui and want to go in the winter to see the whales. We are thinking about January because it fits our schedules the best. I know the weather will be great for sight seeing, but I'm concerned about actual swimming/snorkeling. I'm a Texas girl, so I'm used to being miserably hot during beach months. Will I feel cold at the beach? Who has been in December/January and can give me some insight?
