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
Chesterfield Reservoir is a relatively shallow, high‑elevation impoundment, so its water temperatures follow the seasons and are strongly influenced by snowmelt and air temperatures. In winter the surface commonly approaches freezing, around 32°F (0°C), and the reservoir can be ice‑covered for extended periods. Spring thaw keeps temperatures cool, roughly 36–50°F (2–10°C) through late spring. By midsummer the warmest surface readings typically reach about 60–72°F (15–22°C) on sunny, calm days, with the warmest pockets near shore; temperatures begin falling through the fall into the 45–60°F (7–15°C) range as air temperatures drop.
Swimming at Chesterfield Reservoir is generally possible and used recreationally in summer, but it is not a supervised swimming facility. The cool spring and early summer water and the risk of hypothermia limit comfortable swimming to the warmest weeks, and there are no lifeguards at most access points, so swimmers are asked to exercise caution. Boat traffic, changing depths, and occasional cold currents from inflowing streams can affect safety. Local rules or seasonal restrictions may apply, so visitors typically check posted signs and use standard precautions—life jackets for weak swimmers, accompaniment, and limiting time in cold water.
