*** 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
Secession Lake, like many small inland lakes in South Carolina, follows the regional seasonal pattern of surface water temperatures. In winter months the lake commonly cools to roughly 45–55°F (7–13°C). Spring brings a steady warming with surface temperatures often between about 55–70°F (13–21°C) as air temperatures rise. Peak summer temperatures can reach the mid-70s to mid-80s °F, roughly 24–30°C, especially during heat spells, while autumn sees a gradual decline back toward spring levels as the water loses heat.
Whether swimming is allowed at Secession Lake depends on access and local rules rather than the water temperature alone. In places where the shoreline is publicly accessible and no prohibitory signs are posted, recreational swimming is often practiced, but conditions vary: there may be no lifeguards, uneven bottoms, aquatic vegetation, or variable water quality that affect safety. In some cases, private ownership, conservation restrictions, or concerns about drinking-water protection and wildlife habitat mean swimming is restricted or prohibited. Visitors should check current local guidance, posted signage, and recent water-quality reports before entering the water.
