Hi Murat,
45 degrees is insane! How do you manage to work and breathe at the same time!? I've heard that on one of the Greek islands the working day during the summer is actually a working night! They officially switch to sleeping during the day. But that's maybe a rumor, describing how hot it is!
About going there, I'd really prefer it after the active season. I have local spearfishing competitions during August and September. Then it will all depend on the wallet factor - if I don't get a commission I am supposed to earn by then, I'll be stuck here...
But I'd drop you a line if I decide to go and I'll let you try my new Excalibur!
By the way you cannot dive without a wetsuit in the Black Sea - even now when water temp is 25 - 27C in the upper layers. Around the 10-15 meters it gets down to about 14-15C and there is a cold thermal layer of 8-9C around the 20th meter. That's why all the fish stays in the upper layers where the plankton is!
