Sweers Island Location

-17.1167, 139.6000

-17.11670, 139.60000 View on OpenStreetMap →

Sweers Island sits at -17.1167°N, 139.6000°E, on the coast of Queensland, 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.
