Weather on the Upper Colorado River – Spring 2021
Springtime is still cold in Colorado, especially in the mountains. You are going to want to make sure you bring along a warm jacket, hat, snacks, a thermos full of coffee, wool socks, and gloves. For a little extra boost in warmth, pick up some hand and feet warmers from Walmart or your local fly-fishing shop. Another way to help keep warm is to prevent exposure as much as possible. You can do this by having multiple set-ups – AVA specialists recommend a nymph and streamer on different rods. Fish are moving slowly during the winter and spring season, so you will not have to wake up at the break of dawn to catch anything. Wait until the temperatures warm up around noon to increase your chances. You will want to find areas in the water that are deeper where it is warmest. Remember to take the temperature and elevation into consideration when determining what time to fish.
