That's a big air temp range. At 70 degs, I'm in shorts and barefoot, particularly if sunny. At 30, I'm in the bar telling sailing stories.
If you're going to get wet, you're going to get cold at any of these temps. But, if that's not a significant concern, I find long pants and a fleece that I can zip up around my neck is fine down to about 60 degs, while underway, and 50 degs while at anchor. Sailing in the 50s requires a mid-weight foulie. Below that, I got nothing, cuz I don't want to be there. I've done it, but only because I had to do a delivery.
Those water temps should be your real concern. You will have minutes before you start to become stiff and around an hour before death. Your focus should be on tethers, etc, to keep from being in it or having a raft, if you must abandon ship.
