San Carlos Location

27.9618, -111.0371

27.96179, -111.03710 View on OpenStreetMap →

San Carlos sits at 27.9618°N, 111.0371°W, on the coast of Sonora, Mexico. 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.
