*** Forecast - Our water temperature forecast
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
Brantley Lake, a managed reservoir in southeastern New Mexico, experiences a wide range of surface temperatures through the year. In spring the water commonly sits between about 55 and 70°F (13–21°C) as warming begins. Summer brings the warmest conditions, with typical surface temperatures around 75–86°F (24–30°C), making the lake feel inviting on hot days. During autumn the water cools again to roughly 60–75°F (16–24°C), and in winter surface readings often fall to about 40–55°F (4–13°C) depending on air temperature and reservoir releases. Local factors such as depth, seasonal inflows from the Pecos River and reservoir operations can cause noticeable short-term variation in temperature and stratification.
Swimming at Brantley Lake is generally allowed as part of the park’s recreational offerings, but it is treated as an unguided activity and subject to practical and safety constraints. There are no lifeguards, and fluctuating water levels, submerged hazards, occasional algal or clarity issues, and boat traffic mean swimmers must exercise caution. Seasonal temperatures influence comfort and risk: summer water is usually comfortable, whereas colder shoulder and winter water carries hypothermia risk. Park advisories, posted regulations and recommended personal flotation devices should be followed to reduce hazards associated with swimming in a working reservoir.
