Puerto San Antonio Location

-40.8000, -64.8833

-40.80000, -64.88330 View on OpenStreetMap →

Puerto San Antonio sits at -40.8000°N, 64.8833°W, on the coast of Río Negro, Argentina. 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.
