Edisto Island Location

32.5503, -80.2971

32.55035, -80.29714 View on OpenStreetMap →

Edisto Island sits at 32.5503°N, 80.2971°W, on the coast of South Carolina, United States. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
