End of december through march - 5/4 - 5 mil boots and gloves
April and may- 4/3 -5mil boots - 3 mil gloves
june - 3/2 3mil boots no gloves
july- 2/1 spingsuit - but i bring my 3/2 just in case
August and sept - boardies, but i bring my spring and 3/2 just in case
oct 3/2 - 3 mil boots
nov and december 4/3 5mil boots 3 mill gloves
This is all a rough estimate based on air temps and water temps. Inbetween seasons I usually bring different stuff just incase because i'd rather be hot than cold.
There are pros and cons to both 3/2 and 4/3, which is why people have both. If I had to buy just one, I would get a good 3/2 and make sure the seams are sealed. I have an ONeill Epic 2 and it works great. I think it was like $150 brand new. I had a very cheap Quiksilver suit (was like $90) that didn't have sealed seams and that thing leaked like a BP oil rig.
While 4/3s are obviously warmer, 3/2s are less restrictive and weigh less and with a sealed seam, you can go in a little colder water.
With a 4/3, to really optimize it's use, you will need gloves, booties and a hood (yuck). You can't go wrong with a good 3/2. Just my $0.02.
