Umboi Island Location

-5.7000, 148.0670

-5.70000, 148.06700 View on OpenStreetMap →

Umboi Island sits at -5.7000°N, 148.0670°E, on the coast of Morobe Province, Papua New Guinea. 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.
