Not in the mountains. The higher the elevation, the colder it is. We spent 1 winter in Rockport TX at the ooast. It was extremely nice, but very humid. This past winter was cold and rainy there. The RGV in TX (way down by the border) is usually nice, but they got in on the cold snap this past winter too. We were in Yuma AZ and it was nice , even hot sometimes, but it also gets cold at night. Sometimes down into the 40's. When it's desert dry - 40 is cold, and it's often windy. N Mexico is cold in the winter as most of the state is over 2,000 ft elevation ( a lot of high desert) and many areas get snow. Windy here a lot too. We have yet to find the great spot. We are waiting for the 2019 winter forecast that comes out beginning of Sept. Sitting in NM now and will either head to AZ or TX depending on what that forecast says. It's a crapshoot.
