*** 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
Omak Lake, located near the city of Omak in north-central Washington, experiences notable seasonal variation in surface water temperature. In spring the lake typically warms from chilly levels around 45–60°F (7–16°C) as air temperatures rise and ice melt finishes. Summer brings the warmest conditions, with surface temperatures commonly ranging from about 60–75°F (16–24°C), though shallow areas can heat slightly higher on hot, calm days. In autumn the water cools back toward approximately 50–65°F (10–18°C) as nights lengthen, and in winter surface temperatures often approach near-freezing to around 32–40°F (0–4°C) where ice or very cold water persists.
Swimming at Omak Lake is generally allowed because it is a public natural waterbody, but conditions and local advisories determine when it is advisable. The lake’s often-cool spring and fall temperatures and near-freezing winter waters present a risk of cold-water shock, so swimming is most practical in summer when surface temperatures are warmest. Visitors should check current water-quality notices and be aware that many natural shorelines lack lifeguards, gradual entry, or emergency services. Assessing weather, water clarity, and personal readiness for cold water are important for safe recreational swimming.
