I dove a wetsuit for over 200 dives through 2 winters before going dry. Yes, it's cold. But it IS doable, especially for just a couple of dives. The fish & invertebrate life here is well worth being cold for a couple of hours. If you dive wet, be sure to get warm between dives. Now that the weather is getting nicer, that isn't too hard but if it should be a cloudy, chilly day just make sure you have a hat and jacket, possibly gloves, and something warm to drink between dives. Also helps to eat a little something.
