Fontein Location

38.8913, -77.0200

38.89130, -77.01996 View on OpenStreetMap →

Fontein sits at 38.8913°N, 77.0200°W, on the coast of Indonesia. 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.
