Hi, I'm planning a short escape to LHI while on my trip to Oz. How's the weather then? is it warm enough to snorkel wihtout a neoprene? I'm aware it's the beginning of spring and other places mainland might be a little bit chilly, but as it seems to be a subtropical locations, I was wondering whether it is worth to stay more or less depending on the temperatures and possibility (or not) to swim and so.
Thanks!
