Douane Location

36.4477, 10.7557

36.44766, 10.75570 View on OpenStreetMap →

Douane sits at 36.4477°N, 10.7557°E, on the coast of Nabeul, Tunisia. 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.
