wilkommen! H.B. low's 60's (60 on this board but lifeguards say more like 62-65.) i like my 4/3 until the high 60's... more cold-tolerant folks like the 3/2 at this point. the air is going to warm up thursday or so, so you may roast in a full suit. your long board will work nicely as the waves will be small right now.
if you come across a sponger with shades, try not to run me over. B^)
