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
Tenmile Lake’s surface temperatures vary considerably through the year and are strongly influenced by coastal weather, wind, and lake depth. In winter the water is typically quite cold, often in the upper 30s to upper 40s °F (about 3–9 °C). Spring brings a gradual rise, with surface readings commonly between the mid-40s and around 60 °F (7–16 °C). Peak summer surface temperatures tend to range roughly from the low 60s to the low 70s °F (16–22 °C) on warm, calm days, though deeper water remains colder. By fall the lake cools again, with surface values generally falling into the 50s to low 60s °F (10–17 °C). Short-term swings can be large after storms or heat spells, and thermal stratification means subsurface temperatures are usually several degrees lower than the surface.
Swimming at Tenmile Lake is allowed and is a common recreational use, particularly at popular shorelines and designated access points, but it is subject to the usual safety and health considerations. Lifeguards are not typically on duty, boat traffic and submerged vegetation present hazards, and cold water—even in summer—can cause shock or rapid loss of body heat. Occasional water-quality advisories for bacteria or algal blooms can close swimming areas, so visitors should heed posted signs and local guidance, enter gradually to gauge temperature, and follow standard lake-safety practices.
