*** 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
North Tenmile Lake, near Lakeside on the southern Oregon coast, typically stays cooler than inland lakes because of coastal influences and its depth. Seasonal surface temperatures in winter commonly range from about 40–48°F (4–9°C). In spring temperatures usually climb to roughly 48–60°F (9–16°C). Summer brings the warmest conditions, with surface readings often between 60–72°F (16–22°C), and early fall generally cools back to about 50–62°F (10–17°C). These values can vary with weather, wind, shading, and how recently a warm or cold period has occurred, and deeper water remains colder year-round.
Swimming at North Tenmile Lake is generally permitted and the lake is used for recreational activities including wading and open-water swimming at public access points. However, many visitors find the water brisk even in summer, and prolonged exposure carries a risk of hypothermia when temperatures are on the lower end of the ranges above. Occasional water-quality advisories, such as for algal blooms or bacterial counts, can temporarily discourage or restrict swimming, so checking current local advisories and using common-sense safety measures—life jackets for weaker swimmers and limiting time in cold water—is recommended.
