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
Phillips Lake, located in the Blue Mountains of eastern Oregon near Baker City, is a reservoir known for its cool, clear waters and scenic surroundings. Water temperatures in the lake vary widely with the seasons, reflecting the region’s continental climate. In spring, the lake is fed by snowmelt, keeping temperatures quite chilly, generally around 45–55°F (7–13°C). During summer, surface waters warm considerably, averaging between 65 and 72°F (18–22°C) by mid-July and August. These mild summer temperatures make swimming possible, although the deeper parts of the reservoir remain much cooler. By autumn, the lake cools again to around 55°F (13°C) as air temperatures drop, and in winter it can be near freezing, often with ice forming along the edges.
Swimming in Phillips Lake is allowed and popular in summer, especially in designated recreation areas managed by the U.S. Forest Service. The water is generally clean, and the shoreline features gentle slopes that make entry easy in several spots. However, swimmers should be aware that even on warm days, the lake can feel quite brisk due to its mountain setting and depth. Most visitors enjoy the water for short swims, boating, or fishing, while families often combine swimming with picnicking and camping along the lakeshore.
