St Ouen Location

49.2375, -2.2226

49.23748, -2.22265 View on OpenStreetMap →

St Ouen sits at 49.2375°N, 2.2226°W, on the coast of Channel Islands. 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.
