Air Temp vs Water Temp- when can I get back out!?!

Hello All,
Restarted surfing after 15 years, but now I live in the Northeast of the US (New York). Had a great summer and fall, but now that it's early spring, I'm wondering how soon I can get out there again! The weather has been mostly sunny 55-70 degreesF (13-20 C) but the water temp is only 42 degreesF (6 C)! I have a 4/3 fullsuit and 3mm booties and gloves (should I get a hood, too?) With warmer air temps and sun, how much warmer will the water need to be before I can go out for a comfortable 2 hour session? The beach is a 45min trek through NYC traffic, so I want to have an idea before I just give it a whirl... Thanks for the wisdom...
P.S Apologies to those who already read this- accidentally posted it in the "Gear" section the first time around...
