I live in Northern Nevada and it gets cold here in winter. I love to play tennis and I play almost everyday as long as there is no snow on the court. I am really used to play in cold weather after many years of outdoor tennis in winter months. I regularly play in low 20 F. I play around 8-8:30 in winter months. I remember the coldest day couple of years back and it was 12 F = -11.11 C Share your experience. Playing indoor or inside bubble doesn't count..
