Bertioga Location

-23.7995, -46.0229

-23.79945, -46.02294 View on OpenStreetMap →

Bertioga sits at -23.7995°N, 46.0229°W, on the coast of Sao Paulo, 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.
