Nukualofa Location

-21.1393, -175.2049

-21.13934, -175.20495 View on OpenStreetMap →

Nukualofa sits at -21.1393°N, 175.2049°W, on the coast of Tonga. 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.
