I do the same thing with my students, describe how cold Gilboa is and suggest they put warm water in their suit immediately before entering. I have a tent with heaters in it to keep them warm between dives if needed, that's not usually an issue in June though. You want to know what the students have always said, "It wasn't nearly as cold as you made it out to be." It's cold when you first get in, get your whole face wet before you go under and your body adjusts quickly. Three finger mitts are a little harder to use but they keep your hands warmer and that makes for a more pleasant dive. Make sure you get a wetsuit that fits as well as a rental can, the less water you have exchanging in the suit the warmer you will be. You can also wear long johns (no cotton, get a performance fabric) under your wetsuit for a little extra insulation. A dive skin over the long johns makes putting the wetsuit on easier and you can use that on your tropical dives to protect from stings and scrapes. The fleece lined skins are really nice and eliminate the need for the long johns. I've found that I'm colder if I'm wearing a bathing suit top so I have a cropped fleece tank-top that I wear with my tankini bottoms instead of the regular tankini top. I also have a fleece hat that fits snugly and I can wear it under my hood for added warmth. I am the queen of freezing, my students laugh at me because I'm freezing in my drysuit and they are comfortable in their wetsuits LOL!
Gilboa is a really neat place to dive and there are a lot of interesting things to see. I think you're actually going to enjoy the experience.
