North Sandy Island Location

-21.1000, 115.6500

-21.10000, 115.65000 View on OpenStreetMap →

North Sandy Island sits at -21.1000°N, 115.6500°E, on the coast of Western Australia, Australia. 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.
