I can see that many of the people responding here weren't there January marathon weekend 2010 (sleeting at the start of either the half or the full marathon, not sure which since I wasn't there...they called it Disney On Ice) or Dec 10ish plus a couple days that same 2010 year, or January marathon weekend 2014 and we froze for a day or so Feb 2012, too. Dec 2010 the morning we hit Wizarding World for early entrance we did Flight of the Hippogriff outdoor coaster 14 times in a row. It was 28 stinkin' degrees (not "feels like"). I remember looking at that temperature VERY well. The Hogwarts house scarves that seemed like such a ripoff at $30+ apiece 2 days prior were purchased. $100 in scarves right there. 2014 was sick and wrong cold for a couple days, then the day of my son's Mickey Mile it was 80. Oh I forgot...5K day January 2015 it was 33 when I got to my volunteer spot, and by the time DS and DH got to their corrals it was 31. That was awesome. And a month later for the Princess 5K it was colder, but I heard that they actually handed out space blankets and had heaters out for that...not for the January 5K, though!
So when people talk about Florida winter always being 70 during the day, I laugh. Y'all haven't experienced 35 degrees at night with the wind whipping across the lake while trying to watch Illuminations without breaking your teeth from your jaw chattering. Shudder.
How do you dress/plan for a long day at a park where the temperature may be in the 70/80s during the day but go down to the 50/60s at night?
Not very different than at home.
But when REAL winter weather hits in Florida, it gets nasty.
Layers for sure and don't forget a bathing suit. I know it sounds crazy but swimming in a luscious, warm pool is fabulous on a cool evening.
Nothing crazy about it.
But if it's 50, you want to keep your hair out of the water, or if it gets in the water you want it still in the water. Because wet hair hitting your neck outside in the 50 degree weather can make you very cold!
Keep in mind that 50/60 degrees feels different in Florida than it does in other parts of the country. Due to the humidity it feels "colder" at those temperatures there, so while I may walk around outside in a t-shirt and shorts at 60 degrees, in Disney I would probably wear a pair of leggings and a sweatshirt or jacket over my t-shirt!
YES.
I'm from MN and I wore shorts basically every day in Disney in December. One day I changed into jeans before we went back to the park in the evening, knowing we'd be there until really late and it was a slightly chilly day. Another day I wore a light zip up shirt in the morning but by early afternoon I was down to tank top and shorts. We got there at 7 am that day and it was still dark, so that's probably why it was chilly still in the morning.
I did have an older woman on the bus tease me (light heartedly) saying she could tell I wasn't from Florida because I "wasn't dressed appropriately". She was from Fort Lauderdale, lol. I felt great though!
Maybe someday you'll hit the temperatures others on the Dis have experienced, and then you might possibly have different clothes on, or wish you did.
Side note, it was about 33 degrees yesterday, I wasnt the only one in my neighborhood out in jeans and a T-shirt clearing the melting snow from our driveways. So its all relative to wear you come from and what your acclimated to.
OK, so do the same, and stay outside for 12 hours. Occasionally get in an open convertible and drive 45 degrees to simulate Test Track, drive a bit slower for 7dwarves, etc. Really feel what it feels like to be at a themepark in that temperature. And don't forget that the restaurants aren't going to be warm, because their AC hasn't quite turned into heat yet! (sat in air-reach of the doorway at former-Cat Cora's one of those cold Januarys and thought I was going to die of the cold...wow was that cold)
A caveat about the "true northerner" thing. Back home, you usually don't sit outside on a curb or a bench for an hour waiting for evening entertainment to start. Unless it's a sports game and then you actually would dress warmly, maybe even bring a blanket, because sitting still you
would get cold. That's what you can't forget at WDW in winter. In December waiting for
MVMCP at MK on Main Street, we two Chicagoans thought we were warmly enough dressed for the evening's temps in the low 50s. But an hour of sitting on a cold concrete curb under the fake soap snow blowers and we were
freezing.
YES YES YES.
Our first trip was Dec 2010. Got there just at the end of Nov. Oh it was lovely. 70 degrees. Each day it started dropping. We had packed for the first week of weather b/c that's what we could find out. Then it hit the 30s and that one lovely 28 degree morning... We had no clothes for it. DH is not a small guy and I was rather plus sized at the time, and we had budgeted tightly and couldn't just run out to Lane Bryant and Casual Male to buy a new wardrobe. We were NOT warm, the whole time. (we did swim three times though) Then on our departure day, we were bundled up in our flying clothes, and it was 80.
