Cold, cold, cold! The air temperature was 48 in a constant breeze from the northwest and the water temperature was 70 off the beach and 68 at the boat channel. Cold. Vis was down to between ten and fifteen feet. The chop on the intracoastal has lifted sand into the water so it is milky. Nevertheless, my open water student in two 3mm wetsuits (and 24 lbs of lead to sink them) did very well on our fifty-six minute dive. Tobin, the most die-hard bridge diver I know, said he felt pretty comfortable in his 3mm suit with a 3mm hooded vest. He's tougher than I am.
