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
Ozark Lake, located along the Arkansas River near the city of Ozark in western Arkansas, is a wide reservoir created by the Ozark–Jeta Taylor Lock and Dam. Its water temperature varies seasonally, influenced by river flow, depth, and the region’s humid subtropical climate. During winter, the surface temperature typically ranges from 7–11 °C (45–52 °F), keeping the water too cold for swimming. In spring, as temperatures rise, the water warms gradually to 15–21 °C (59–70 °F). By midsummer, the lake reaches its warmest period, with surface waters averaging 25–30 °C (77–86 °F), while deeper sections remain several degrees cooler. In autumn, the water begins to cool again to around 15–20 °C (59–68 °F) as the air temperature drops.
Swimming in Ozark Lake is allowed in designated areas and is most comfortable from late May through early September, when the water is warm and stable. Public recreation sites, including those within Ozark Lake Park and nearby campgrounds, provide access to safe swimming zones along calm stretches of shoreline. The gentle slopes and warm summer water make it ideal for family recreation and cooling off during hot days. Outside of summer, the water becomes too cold for comfortable swimming, though boating and fishing remain popular year-round.
