Very jealous.Just did Million Hope wreck in a 2mm shortie plus a 3mm hood. A Russian guy was diving in a 3mm shortie without hood. On the other hand a German guy just gave up a second dive at Jackson reef because he was too cold in his 5mm without hood. Water temp was a solid 23 Celsius with some pockets up to 25 air temperature about 30.
I guess YMMV is the name of the game when it comes to the 23-26 Celsius temperature range.
