We're headed to AC next Saturday! How much does it cool off at night? I was wondering if we needed to take any long-sleeve shirts or even a light jacket?

We were just there a week ago and there was only one night that I had wished for long sleeves. (and that was on the Island Ferry). But it was a short ride so no complaints.I took the easy way out and wore a long sleeve shirt over a T on the flight there so it didn't mean extra packing.

Just got back 2 days ago--evening temperatures required no long sleeves--I wore sleeveless each night along the beach and even with the breeze it was very warm and comfortable late in the evening. Sleeves would probably be okay but not too necessary.
