Jervis Bay Location

-35.0481, 150.7447

-35.04808, 150.74468 View on OpenStreetMap →

Jervis Bay sits at -35.0481°N, 150.7447°E, on the coast of New South Wales, 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.
