First time to Hawaii, looking for info (diving, places to stay, things not to miss)

We are headed to Oahu during Christmas 2018 and looking forward to doing some beautiful diving! What's the water temp. like in the winter? Do we need more than a 3mm suit?

I was there in March then May of last year. Both times I wore a 3mm shorty and was fine. If I recall, surface water temp was 80 - 82F.

We usually go with a 3mm full suit. Water temp is low to mid 70's in winter. Most of the locals use 5mm or thicker if you can believe it.

I was there last November. It was so warm I kept having to let water into my suit to cool down some.

Don't know about Oahu, but on the Big Island the difference between water temperatures in mid-November and mid-december can be 2-3 degrees F.
