Well, I have lived in Maine and California for most of my young-adult years.
From a weather perspective, it's an acquired taste for sure.
We run the HVAC almost (almost) most of the year, due to the heat and humidity; however, it does not get as humid as Maine or Florida.
Last winter was pretty tough, due to the snowpocolypse that we had, lol. But that is a rare occurrence.
If you want to check the Weather Averages, this is a good website:

Though, I will say... The most north-east you go, people have a lot more of that Southern hospitality.
San Antonio was really nice, the people (for the most part) are very kind and friendly and there's a lot to do there (for date nights/weekends or even getaways/events with the family/kids).
Austin is meh, seems like a baby San Francisco the times that I had gone... Running more on the far left side than anything, especially with their "311" vs. "911" policing now and defund the police movement.
Dallas is alright, lots to do, lots to see, has a pretty nice night life. Reminds me of a smaller LA feel, though crime and homeless has been on the sight incline.
Houston is pretty diverse, warmer temps, more rainfall, lots to do around Houston as well (though I haven't been there much, live more closer to the Dallas vicinity).
Overall, best decision ever was to leave California and move here, honestly.
Everyone we have met and befriended has been more than pleasant, even though we are not born and raised Texans (my wife is also Mexican, which has made no impact on cultivating friendships).
Hope this helps!
