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
Clarks Hill Lake, along the Georgia-South Carolina border, experiences noticeable seasonal swings in surface water temperature. In winter (December–February) surface temperatures typically fall into the mid 40s to mid 50s °F (about 7–13 °C). Spring (March–May) sees a steady rise, with surface readings commonly in the upper 50s to low 70s °F (roughly 14–22 °C). Summer (June–August) brings the warmest conditions, often ranging from the mid 70s to mid 80s °F and occasionally reaching the upper 80s °F in heat spells (about 24–31 °C). In autumn (September–November) the lake cools again, generally moving between the low 60s and mid 70s °F (approximately 16–24 °C). Temperatures vary with depth, time of day, and local inflows, so surface readings can be notably warmer than deeper water.
Swimming is generally allowed at Clarks Hill Lake, particularly at parks and designated beach areas managed by the corps and local authorities, because the reservoir is intended for multi-use recreation. However, there are no universal lifeguards or swimming bans across the entire lake, and safety considerations—boat traffic, submerged hazards, sudden depth changes, and occasional water-quality advisories such as algal blooms—mean swimmers should choose marked areas, follow posted rules, and check current conditions before entering. Overall, summer and early fall offer the most comfortable water for swimming.
