Port Clinton Location

41.5120, -82.9377

41.51200, -82.93769 View on OpenStreetMap →

Port Clinton sits at 41.5120°N, 82.9377°W, on the coast of Ohio, 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.
