*** 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.

The Santee River, flowing through South Carolina, is a significant waterway that provides a mix of scenic beauty and recreational opportunities. The river's temperature varies depending on the season and the region. In the warmer months, especially during summer, the water temperature can rise to between 70 and 80°F (21–27°C), making it relatively comfortable for swimming. During the cooler seasons, the water temperature can drop, especially in the upper parts of the river, where it can range from 50 to 60°F (10–16°C), making swimming less appealing.
Swimming in the Santee River is possible, especially in its slower-moving sections and near recreation areas where the current is more manageable. The river’s calmer stretches, such as near parks and lakes, are more suitable for leisurely swimming or wading. However, in other parts of the river, particularly near the confluence with other bodies of water, the current can be strong, and the water levels fluctuate, so swimmers should be cautious. Aside from swimming, the Santee River is popular for fishing, boating, and canoeing, with its surrounding landscape offering a peaceful environment for outdoor activities.
