San Bartolo Location

-12.3849, -76.7705

-12.38494, -76.77046 View on OpenStreetMap →

San Bartolo sits at -12.3849°N, 76.7705°W, on the coast of Peru. 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.
