Yonakuni Shima Location

24.4500, 122.9330

24.45000, 122.93300 View on OpenStreetMap →

Yonakuni Shima sits at 24.4500°N, 122.9330°E, on the coast of Okinawa, Japan. 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.
