Between fall and spring, a wetsuit is recommended for snorkeling and scuba diving in the Bahamas. When deciding what to bring, consider that you will be diving frequently each day and it takes your body a while to warm up after each dive. Air temperature, the wind and cloud coverage, all these factors affect how fast your body warms back up after a dive. Choosing a wetsuit is a very personal decision, some people wear a full suit in the summer and some dive with a shorty in the winter.
