I'm heading to Perth May 4 - 12th. I'm planning to go to Shoalwater Marine Park for Kayaking and snorkeling.
I checked http://www.marine.csiro.au/~lband/AlanPearce/regional/rotto.html and it says the mean surface water temperature is about 22C. I'm from a warmer climate - and I have a shorty wetsuit.
Is that sufficient for that water temperature? Is it necessary?
