Hey Paige!
Welcome to planDisney. My parents actually live in Texas, so I’m happy to be chatting with a fellow Texan. The fantastic weather and the lower crowds make January an ideal time to visit Walt Disney World Resort.
Unlike Olaf, I’m not a massive fan of Summer. My favorite times to visit Walt Disney World Resort are Fall and Winter. The weather in January is typically less humid and very pleasant. I recommend wearing layers in January. It starts chilly in the mornings, gets to around the low to mid-70s in the afternoon, and then back to chilly when the sun goes down. Now I say typically because Texas and Florida are eerily similar with temperatures. The only thing constant is that it is likely to change. So layers will always be a safe bet. Also, January tends to be drier, but I never go anywhere without a mini umbrella as someone who lived in Florida for six years. A stray shower may appear during your vacation, and you will be happy to have it.
As far as crowds, January overall tends to be lower. Except for a few notable events:
Walt Disney World Marathon: January 5th-9th
EPCOT International Festival of the Arts: January 14th- February 21st (the first week tends to be the most crowded of the entire festival)
Martin Luther King Jr. Weekend: January 15th-17th
These peak times may have higher crowds for the month but I personally find them to be a lot more manageable than other times during the year.
I hope this information is helpful to you in planning your upcoming Walt Disney World Resort vacation!
Let me know if you have any other questions.
