My honest opinion is to pull a 3mm as soon as you get there and dive in that. This will be your base line as its still early and the water will be alot more colder than later on the day. dive in it and see how you feel. you should be warm. like i said my wife is a naturally cold person. set the temp to high in the house, wears a jacket in july at work, takes scalding hot baths and sleeps in sweater pants and a sweater. she likes to be warm. she dove just fine at mammoth in a tyr bathing suit and a rash guard. try and see if you like a 3mm. if you like the way it feels now it should be perfect as its only going to get hotter.if you get a suit that tooo thick you will over heat quickly and end up diving with the zipper undone plus it throws off your boyancy. I install fence's for a living so I am always under the sun. I like to be cool under water so i need no more than some 1.5 neopreen shorts. Just dive with the 3mm suit straight off the bat and see how it works for you. tooo hot, open up the zipper. if your arms and legs are too hot. then you might want to consider getting just a 3mm shorty. you can always add legs later.
