It all depends on how well you tolerate the cold. I wore a 3/2 spring suit this weekend in 64 degree water and was fine. But, I saw a lot of folks out in full suits too. I could have worn my 2 mil vest and been okay too, I did not feel uncomfortable at all.

In 64-67 you would be fine to trunk it for an hour. A springie will be fine for any decent length of session. Bring that wetsuit into a repair shop ASAP though, because the winter is coming and you won't be much good in a 2:1 springie when it drops into the 50s.

that will be totally fine. i've been surfing in shorts and 1 mm top this week to cut the wind. if it wasn't windy i'd just surf in boardies and a rash guard, so a spring suit should be more than adequate. the water is really not cold at all yet and surfline seems to have been undercalling the water temp in southern california lately.

you should be fine, it depends on how warm the air is too, but i have noticed that surfline can be off by like 5 degrees for where i surf, look in the newspaper and see what the actual temp is, but you should be fine.

That's a bit cool for a springsuit but you should be OK. As others have noted the air temperature will be key...if its sunny and warm, no worries...but if its windy or cool you might get cold quickly.

You should be ok. It wouldn't be as cool it you go midday as well. I'm sure you'll get "immuned" to it after awhile.
