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
The Cooper River in South Carolina is a significant waterway known for its calm flow and historical surroundings. The water temperature varies throughout the year, offering different experiences depending on the season. During the summer months, from June to September, the water temperature ranges from 77°F to 86°F (25°C to 30°C), making it warm and inviting for recreational activities, including swimming in certain areas. However, swimming is typically more common in designated spots or during organized events to ensure safety due to boat traffic and varying depths.
In the cooler months, from November to March, the river’s water temperature drops to around 50°F to 65°F (10°C to 18°C). While these cooler temperatures are less ideal for casual swimming, the river remains a popular spot for boating, kayaking, and fishing. Spring and fall, with temperatures ranging from 65°F to 75°F (18°C to 24°C), provide comfortable conditions for those who enjoy water-based activities without the summer heat.
Although swimming in the Cooper River is possible, it’s not the most common activity due to its use as a navigational route and the presence of wildlife. Those who want to swim typically do so at nearby lakes or designated recreational areas rather than directly in the river. For safety, always check for local guidelines and conditions before diving in.
