Colonia Location

-34.4667, -57.8500

-34.46670, -57.85000 View on OpenStreetMap →

Colonia sits at -34.4667°N, 57.8500°W, on the coast of Departamento de Colonia, Uruguay. 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.
