Hervey Bay Location

-25.2882, 152.7677

-25.28815, 152.76766 View on OpenStreetMap →

Hervey Bay sits at -25.2882°N, 152.7677°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.
