*** 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
Leesville Lake’s water temperature varies with the seasons and with depth. Surface readings in winter commonly fall into the mid-30s to mid-40s °F (about 2–7 °C), while spring warms to roughly 45–65 °F (7–18 °C) as sun and runoff raise surface layers. In summer the surface often reaches the mid-70s to mid-80s °F (about 24–29 °C) on warm days, and in fall temperatures typically decline to the 50s–70s °F (10–21 °C). Like many reservoirs, Leesville stratifies in summer: surface water is significantly warmer than deeper layers, so sub-surface temperatures can remain much cooler even when the top feels warm. These seasonal and vertical differences affect comfort and safety for swimmers.
Swimming in and around Leesville Lake is commonly practiced but not highly regulated by public beaches, so most swimming happens from private shorelines, docks or boats and is done at the swimmer’s own risk. There are typically no lifeguards, and certain areas—near dams, intake structures, marinas or posted private property—are off-limits for safety and operational reasons. Cold, deep water and boat traffic are the main hazards, so swimmers are advised to heed signage, wear life jackets as appropriate, avoid restricted zones, and be aware that cooler temperatures can cause cold-water shock even when air temperatures are warm.
