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
Lake McClure is a foothill reservoir in central California whose surface temperatures vary widely with the seasons and with depth. In summer months (June–September) surface temperatures commonly range from about 68–80°F (20–27°C), making surface swimming comfortable on warm days, though deeper water remains considerably colder. Spring (March–May) and fall (October–November) see temperatures nearer 52–68°F (11–20°C), while winter (December–February) surface readings often fall to roughly 45–55°F (7–13°C). Because McClure is a reservoir, thermoclines and colder deep water persist year-round, and rapid temperature changes near the surface can increase the risk of cold shock; water under roughly 60°F (15–16°C) can pose hypothermia hazards for unprepared swimmers.
Swimming at Lake McClure is generally permitted as part of its recreational use, and people often swim from shore, beaches, or boats; however access and specific allowed areas are governed by local recreation rules and can change with water levels or advisories. Safety considerations—cold water, submerged hazards from fluctuating shorelines, boat traffic, and occasional water-quality advisories—mean swimmers should follow posted signage, use flotation when appropriate, and be aware that designated swim areas may be limited and not lifeguarded.
