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
Greers Ferry Lake, a large reservoir in North Central Arkansas, is known for its deep, clear waters, which moderate its temperature fluctuations. In the cool winter months, the surface water temperature typically ranges from the 40s to low 50s F (4∘C to 13∘C). During the long, peak summer season (July and August), the surface layer warms significantly, often reaching a very comfortable range for swimming, generally peaking between 75∘F and 82∘F (24∘C to 28∘C). Due to the lake's depth, the water below the surface often remains significantly colder.
Swimming is widely permitted and highly encouraged in Greers Ferry Lake, as it is a major recreation hub managed by the U.S. Army Corps of Engineers. The lake features over a dozen recreation areas, many of which contain designated swimming beaches and areas, confirming the activity is fully supported and popular. However, these designated beaches are typically unsupervised by lifeguards, meaning all swimming is strictly at one's own risk. Swimmers must be cautious of the heavy boat traffic, the deep water, and the potential for cold upwellings near the dam or in deeper areas, which can pose a risk of cold shock.
