Just closing the loop on this upon our return. I dove all week in my 3mm with 5mm hooded vest under. 2mm socks and gloves were fine. The only two dives where I needed The 7mm were the last day at Cousins Rock. Water temp 63! Diving was simply amazing!
May I ask if you had schooling hammerheads during your trip in early March?
I've read people saying that hammerheads thin out during Feb-Apr in Galapagos, so I'm curious to hear your direct experience. Many thanks.
