If you choose to do the dolphin swim, that water will be the coldest in the park with a water temp in the low 70's. The good thing is, the dolphin interaction is so interesting and engaging (and fun!) that you tend to forget about the cooler water quite quickly because your attention is elsewhere
.
The Grand Reef is the second coolest. The Fresh Water Oasis and Lazy River are the warmest (think bathwater warm.....its awesome).
From the DC website:
Water Temperature
The temperature of our pools remains constant throughout the year. The fresh water Serenity Bay and Wind-away River are maintained around 85-88 F (30 C). The salt water dolphin pools maintained around 72 F, and The Grand Reef are 77 F (25 C).
We went last year around the same time (our visit was on New Years Day) and we had a gorgeous day with air temps in the low 80's and sunshine. Now, being winter, it took a while to warm up to that temperature and the morning was quite cool. The wetsuits helped alot and there were heaters scattered throughout the dining area that you could dry off and warm up in a hurry if need be.
Despite it being January, it got nice enough for us to do this in the afternoon:
Just another reason why I love Florida!!!
I wouldn't hesitate to go in the winter again. I would, however, be sure to have a "plan B" to be able to switch to an alternate day (pending availability, of course) should the area experience a brief cold snap on the date we had planned to visit.
