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
Hills Creek Lake, a reservoir in western Oregon, experiences a wide range of surface water temperatures through the year. In spring the lake is typically cool, with surface readings often from about 40–55°F (4–13°C) as snowmelt and chilly runoff dominate. By summer the upper layer warms most days, commonly reaching roughly 60–75°F (16–24°C) on warm afternoons, though exact temperatures vary with air temperature, sunlight and wind. In autumn the surface tends to decline to roughly 45–60°F (7–16°C) as cooler weather and turnover begin, and in winter temperatures frequently fall to the mid-30s to mid-40s°F (2–7°C) near the surface, with colder conditions at depth.
Swimming at Hills Creek Lake is generally allowed in recreational areas but is done at visitors’ own risk; many lake sites have no lifeguards and local rules or signage should be followed. Seasonal cold and sudden temperature changes, boat traffic, submerged timber and drop-offs make swimming potentially hazardous outside the warmest weeks, and water quality or access points can vary after storms or drawdowns. For safe enjoyment, swimmers should choose designated day-use spots, wear a life jacket if appropriate, and be mindful that comfortable surface temperatures are most likely in mid to late summer.
