Belle Ile Location

47.3364, -3.1810

47.33642, -3.18104 View on OpenStreetMap →

Belle Ile sits at 47.3364°N, 3.1810°W, on the coast of France. 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.
