Sepetiba Location

-22.9674, -43.7056

-22.96743, -43.70564 View on OpenStreetMap →

Sepetiba sits at -22.9674°N, 43.7056°W, on the coast of State of Rio de Janeiro, 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.
