Moses, water temp was around 23-24C and I was fine with my 5mm full suit plus a 3mm hooded vest. I went once with Sea Escape and once with MV Valentina and they were both very good operations. I was told that it is not allowed to fly a drone at Socorro Island as there is a military base there, though I flew my drone a couple of times at San Benedicto. It is a really beautiful island. Once my drone attracted the interest of heaps of birds, I guess I was lucky that I didn't lose it. You can check out my youtube channel for the videos if you are interested.
Thanks. I have been there twice but both in Jan/Feb and that should be why I did not experience challenging conditions. Your video reminds me my good time there, thanks. I hope I will have chance to go there again, next time in May for sharky Roca Partida.
