Hirara Location

24.8000, 125.2830

24.80000, 125.28300 View on OpenStreetMap →

Hirara sits at 24.8000°N, 125.2830°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.
