We have found that the Winter months in Kauai have an ocean that is not as user friendly for snorkeling and Diving as the Summer. Of course if you are a surfer then its the best time to be there! Regardless we had a good time during our week. Tubing on the irrigation canals and snorkeling on the Poipu side were the highlights. Also on our "homeless day" (checkout is in the morning and flight is late) we drove around to the other side of the island and enjoyed the views at Waimea Canyon. It was a gorgeous sunny day, great for photography.
