I suppose for overly hot weather WashU is going to be out, although my kid claimed the St. Louis weather wasn’t too bad this year.
I have heard that the Physics program isn’t that diverse. There is currently only one female professor on the tenure track and there was a professor in the department that made sexist and homophobic comments to the local papers.
Math is hit or miss too at WashU. Some classes are taught well, but the introductory Calculus classes are definitely taught differently from the high school norm. No more plug and chug, but more of using concepts and proofs. Calculus 3 (Multivariable Calculus) is more straightforward.
CompSci is up and coming at WashU but the Engineering department is obviously not the main focus of the school.
WashU is pretty supportive of gender identity, even though Missouri is a red state. St. Louis is liberal compared to the rest of the state, which isn’t really saying that much for somebody from California.
For CompSci, UIUC and UT-Austin are good, but the size of the schools might not work out. And both are not known for nice weather. Johns Hopkins is supposed to be good in math, but Baltimore is supposed to get really nasty weather wise with its humidity.
