Franklin Harbour Location

-33.7000, 136.9500

-33.70000, 136.95000 View on OpenStreetMap →

Franklin Harbour sits at -33.7000°N, 136.9500°E, on the coast of South 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.
