7mm should be fine for your water. Don’t get me wrong, you’ll get a chill near the end of the dive so you’ll want to warm up. I dive in the pacific northwest and our summer temps can get down to the 40s under the thermocline. Today my water temp was 48 and I was in for 90+ minutes between two dives without getting cold. Where you’ll get cold is during your SI. Bring hot coffee or soup in a thermos that helps. Invest in a parka. You’ll do fine.
