BCT at Fort Sill, OK

Shipping to Fort Sill for Army Basic on November 25th and I’m curious how bad the winter actually is there compared to summer cycles. I’m from northern Iowa and already work outside in the cold/wind a lot, so I’m used to winter weather, but I’ve heard Fort Sill winter can still suck because of the wind, mud, freezing rain, etc.
For people who went during winter:
Was it actually brutal or overhyped?
Would you rather do Fort Sill in winter or summer?
How bad are the mornings/field exercises?
Does being from a colder state help much?
Just trying to get realistic expectations before shipping lol.
