You may find it windier and cooler than usual but once you get down to Mexico it will be nice. The stops in MX itself the temps were like in the low 80's. Comfortable but wear sunscreen. Cruising the MX Riveria in Jan you may encounter whales and possibly dolphins. I cruised it the 1st week in Feb. and saw many whales and even heard them "singing" early in the morn. That was definately a highlight of this cruise. Happy sailing!
