Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Fort Collins, Colorado, is home to several bodies of water, including the Cache la Poudre River and several lakes and reservoirs that provide opportunities for water-based recreation. However, the water temperatures in these areas can be quite cold, especially in the spring and early summer when snowmelt from the Rocky Mountains feeds into the rivers. The Cache la Poudre River typically has water temperatures between 40°F (4°C) and 60°F (16°C) during the early spring, gradually warming up to around 60°F to 70°F (16°C to 21°C) in the summer. While these temperatures are refreshing for activities like rafting, kayaking, and tubing, they are generally too cold for comfortable swimming.
For those looking to swim, there are several reservoirs and lakes in the area that offer warmer water for a more enjoyable experience. Fort Collins' Boyd Lake State Park and the nearby Cherry Creek Reservoir are popular swimming spots during the summer months. The water in these areas tends to warm up more easily, reaching temperatures between 65°F (18°C) and 75°F (24°C) in the summer, making them more suitable for swimming. These lakes provide a great setting for not only swimming but also boating, fishing, and relaxing on the shores.
While Fort Collins' rivers are more suited for cooler water activities, its reservoirs and lakes provide ample opportunity for swimmers to cool off and enjoy the outdoors. Whether you're looking for a refreshing dip in the river or a relaxing swim in one of the warmer lakes, the city offers a variety of water options that cater to different preferences.
