I've been to Maui in December and they still offer plenty of tours.
I am a weak swimmer as well and I feel most comfortable booking a kayak/snorkel tour. You can opt to keep your life vest on when you snorkel. I always do. The advantage of snorkeling this way is that you have someone supervising your group and they take you into deeper waters, sometimes only accessible by kayak.
