Stack Island Location

-40.6000, 144.7833

-40.60000, 144.78330 View on OpenStreetMap →

Stack Island sits at -40.6000°N, 144.7833°E, on the coast of Tasmania, 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.
