*** 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
Lake Charles, a 645-acre reservoir located within the Lake Charles State Park in Northeast Arkansas, experiences water temperatures consistent with the region's climate. In the cool winter months, the surface temperature ranges from the 40s to low 50s F (4∘C to 13∘C). During the long, peak summer season (July and August), the lake warms significantly, with surface temperatures often reaching a very comfortable and warm range for swimming, generally peaking between 75∘F and 82∘F (24∘C to 28∘C).
Swimming is widely permitted and supported at Lake Charles, specifically at the designated swimming beach within the State Park, which confirms its status as a recreational site. The Arkansas Department of Health includes the lake on its swimming beach inventory. However, the beach is explicitly stated to be unsupervised, meaning there are no official lifeguards on duty, and all swimming is strictly at one's own risk. Visitors should be cautious, as the lake is also very popular for fishing, meaning the presence of fish hooks and submerged lines is a potential hazard in the water.
