Went to Orlando week of Thanksgiving this year. One day it was in the 80's. We were all in shorts going on the wet rides in IOA. The next day we were freezing to death. Don't know for sure what the temp was but we thought we could handle anything remotely chilly being from Boston, but we had to wear three layers and still froze. Been watching the news lately and it seems to be very cold in Orlando. Is this unusual??
