*** 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 Greenwood, a reservoir in upstate South Carolina, experiences notable seasonal shifts in surface water temperature. In winter the lake commonly cools to roughly 45–55°F (7–13°C). During spring warming brings surface temperatures into the mid‑50s to low‑70s°F (13–22°C) as runoff and air temperatures rise. Summer is the warmest season, with typical surface readings around 75–85°F (24–29°C) and occasional pockets reaching the upper 80s°F (30–31°C) during heat spells. In autumn the lake usually cools back into the 60–75°F range (16–24°C) as air temperatures moderate. These are general surface temperature ranges; deeper water remains cooler and localized conditions vary with weather, wind and inflows.
Swimming at Lake Greenwood is generally allowed and commonly practiced from public parks, private docks and shoreline recreation areas. The lake is managed for multiple recreational uses, so designated swimming spots and waterfront access make bathing feasible, but conditions vary by location and season. There are typically no lifeguards at most sites, and watercraft traffic, submerged obstacles, steep drop‑offs and occasional algal blooms can limit safe swimming in some areas. Visitors are advised to follow local advisories and signage before entering the water.
