january weather

We are leaving on the Pride Jan 25th and I am wondering what the temperature has been like in the ports..70s or 80s? Also water temperatures...hot, warm, cold? We are hitting Costa Maya, Belize, Grand Cayman and Mahagony Bay. I know its a few weeks away but the kids were wondering if they would need to pack for chillier weather ... Although we are in the Philly area and anything will be warmer at that time than here!

It will most likely be in the 80s in those ports in January. Have fun!

Thank you!
