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
Don Pedro Reservoir (Lake Don Pedro) experiences a broad range of surface water temperatures through the year. In summer, surface temperatures commonly run roughly 70–80°F (21–27°C), and in shallow, sun-warmed coves can approach the mid-80s°F (around 29°C) on hot afternoons. Spring conditions are noticeably cooler, with waters often between about 45–60°F (7–15°C) as snowmelt and runoff keep the lake chilly. Fall waters typically cool to roughly 50–65°F (10–18°C) as air temperatures drop, while winter surface temperatures commonly sit near 40–50°F (4–10°C). Deeper parts of the reservoir remain much colder year-round due to thermocline stratification, so temperatures below the surface can be substantially lower than readings at the shore.
Swimming is generally permitted at public beaches and day‑use areas around Don Pedro, and the reservoir is used for recreational swimming during the warmer months, but conditions and rules vary by site. There are typically few or no lifeguards, and hazards such as heavy boat traffic, sudden drop-offs, submerged structure, fluctuating water levels and the risk of cold‑water shock make caution important. Water quality and access can change with seasonal operations and local management, so visitors should follow posted signage, use flotation when appropriate, and check current conditions before entering the water.
