Suku Location

26.5500, 128.0330

26.55000, 128.03301 View on OpenStreetMap →

Suku sits at 26.5500°N, 128.0330°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.
