Getting very excited four our upcoming trip to CSA - 4 1/2 days to go!

Anyway, starting to think about packing and started wondering if a sweatshirt/windshirt might be a good idea for evenings walks along the beach, etc.? I've looked at the 10-day forecast and it looks like the low temps are about 75, but wondering how it actually "feels" with the sea breezes?

Coming from MN, where our highs lately have been around 50 (60 on a REALLY nice day!) I'm sure I'll be fine, but my wife gets chilled easier.

Thanks!!
