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
Long Branch Lake in Missouri experiences a typical Midwestern seasonal cycle in surface water temperature. In summer, surface temperatures commonly reach about 75–85°F (24–29°C), and during heat waves can approach the mid-80s F (around 29–30°C). Late spring brings a warming trend, with waters generally in the 50–70°F range (10–21°C) as the lake stratifies, while early spring and late fall see cooler conditions around 40–55°F (4–13°C). In winter the surface often drops toward near-freezing, roughly 32–40°F (0–4°C); ice cover may form in unusually cold periods but is not reliably thick. Temperatures vary with depth, weather, and inflow, so surface readings are warmer than deeper water.
Swimming is permitted at Long Branch Lake in designated beach and recreation areas, and many parks open swimming seasonally when water and weather are suitable. The warm summer temperatures make open-water swimming comfortable, but there are no universal lifeguards at all sites and conditions can change quickly, so swimmers should exercise caution. Cooler shoulder-season waters raise hypothermia risk, and occasional water-quality or algal advisories can restrict swimming; users should follow posted signs and local management guidance before entering the water.
