I've seen cast members wearing coats and gloves when it's 65!

Here in NH most people don't get their "winter clothes" out until it's below freezing.
Actually I just checked the Orlando forecast and they are in a small cold spell. Mid to low 60 during the day mid 40s at night, but it 's going back to normal starting tomorrow. 70s and 80s in the day, 60s at night.
You can get the long range forecast on line for most anyplace in the world ... wonderful! THAT will tell you how to dress you next trip!
