Cold compared to what? I've been diving Martha's on and off for a decade in nothing more than a skin suit usually. During the hot summer, it's pretty comfortable until the first thermocline (30 ft or so, variable during the year). Then it cools off in a hurry. If you want to visit the bus, bring your 6mm...the cold at 50ft will go right through you..
Cold at the bus. not that bad at the buildings in the warm months.
