Gymea Bay Location

-34.0496, 151.0864

-34.04960, 151.08640 View on OpenStreetMap →

Gymea Bay sits at -34.0496°N, 151.0864°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.
