✅ As of today, the minimum water temperature ranges from 79°F (26°C) to 82°F (28°C). This is very warm water, allowing for extended stays without any discomfort. Swimming in these conditions will be particularly enjoyable, making it the ideal temperature range for those who want to relax in the sea. Additionally, water in this temperature range is suitable for children and elderly people, as it is comfortable for prolonged stays.

It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

Annual Water Temperature Trend

Savannah sits on the southeastern Atlantic coast of the United States and is influenced by a mix of open-ocean and estuarine waters. Sea surface temperatures follow a clear seasonal pattern: in winter (December–February) coastal and estuary waters typically range from about 12°C to 16°C, spring (March–May) sees a rise to roughly 15°C–22°C, summer (June–August) is the warmest period with temperatures commonly between 24°C and 29°C, and autumn (September–November) usually cools to roughly 20°C–25°C. Local conditions vary with tides, river outflow and recent rainfall, so water can feel cooler or murkier after storms or during strong tidal exchanges. Shallow bays and marsh channels heat or cool faster than the open ocean, producing localized differences from the offshore measurements.
