Iwasaki Location

40.5833, 139.9000

40.58330, 139.89999 View on OpenStreetMap →

Iwasaki sits at 40.5833°N, 139.9000°E, on the coast of Aomori, 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.
