We swam Dec 2010 at 50 degrees. Water is heated, but the air is not. So once a body part got wet, you wanted to keep that body part under the water. I had long long hair at the time and it wasn't staying up and it made my head sooo cold to get even my hair wet.
And getting out is NO joke.
I'm not sure they allow it anymore, when it's that cold, though. When we were there last January for the marathon weekend again, it was that cold again, and the pools were all closed. It's just not really safe for people, and it's not good for the lifeguards.
It doesn't matter where you're coming from. After the winter of 2010, I'll never be caught without the full complement of winter gear at Disney in December (January and probably February as well). Hopefully you won't need any of it. But nobody wants to budget coats, hats and gloves for a family at WDW prices.
You might be used to cold temps at home. But you probably don't head out and stay outdoors most of the day. So even if it's not as cold as it is at home, you'll feel it more.
We were there the first week of December in 2010. It was all over the news about record cold. I packed my Under Armour cold weather tops for some reason that year and it was a life saver. We did end up,buying our DD a Tinkerbell hoodie but we layered up and it worked. There are a few pictures of me with a red face because the wind really kicked up our last night but dealing with cold is much better than dealing with heat at the park.
I will say this, the final morning we were there it was 29 degrees when we got to MK. Between the cold and the low crowd count it seemed that there were less than 100 people in the park until noon. Main Street looked deserted when we walked in. We literally walked up to the Merida meet and greet (this was when it was new.), space mountain and Pooh with zero wait. It was amazing. We were sopposed to leave at noon to head home but didn't end up leaving until almost 6pm because the park was so dead. We didn't get home until after midnight.
We were there early December last year, temps at night maybe mid-upper 40s some nights, mostly mid 50s though. We took layers, put coats in lockers for day and got them out at night. I does cool down quick when the sun goes down. Put on a base layer insulated underware for MVMCP on the night we went, talking temps in 50s with 10-15mph wind. You know us northeners, anytime in winter you talk wind we start to figure wind chill temps. We were everywhere from coats to shirt sleeves for the time we were there. Also with the pools, one night we went to beaches and cream for ice cream, laughed because the pool was right there, lifeguards had on parkas holding their floatation devices. Nobody was in pool.

Yea we did but I can't remember what week we were there. It seemed pretty low that year too. This was before DD was in first grade so it was the last year we got to during a slow time. We definitely got spoiled those two years but it helped us plan and deal with the years we have gone since with higher crowd counts.We were there the second week of December and had a similar experience. We also enjoyed what the temps did to the crowds. Did you go back in 2011? Weather was gorgeous, and crowds were down. My theory is that people were too afraid to try December again that next year.
My daughter still swims in the bitter cold. The water is quite warm. It's the run back to the room after that gets you.![]()
I know, we have a outdoor hot tub and boy does it feel great when you're in it in the winter, but the getting out and back to house is different story!We were there the second week of December and had a similar experience.

So funny. Did you look at the forecast for today before posting? Classic weather in the SE.It's 11/22 and is still pretty hot, high 70s today. We are still wearing tank tops and shorts.
Haha, that would be great!!!50's - 80's
It was honestly the worst trip I ever had, but whenever I started to feel sorry for myself I just thought about all those farmers who were losing their entire orchards and livelihood to the recording breaking cold. I got over myself real quick. 
Haha, that would be great!!!
20's-80's generally.
