Hot Water Summer

Hello fellow Texans, I had a question related to the cold water faucets. I am aware that the water runs warmer during the summer because of the source. But s sometimes I'm waiting for like 5 minutes for my cold water. Is there any way to make my cold water cold? Haha. During the summer I also like taking a cold shower, but instead of waiting for the water to get hot, I have to wait for it to get cold! Anyone have a resolution no one has thought of yet? Haha
