Porto Rio Grande Location

-32.1000, -52.1000

-32.10000, -52.10000 View on OpenStreetMap →

Porto Rio Grande sits at -32.1000°N, 52.1000°W, on the coast of Rio Grande do Sul, Brazil. 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.
