Waikawa Harbour Location

-46.6460, 169.1438

-46.64598, 169.14377 View on OpenStreetMap →

Waikawa Harbour sits at -46.6460°N, 169.1438°E, on the coast of Southland, New Zealand. 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.
