San Cristobal Location

-0.8675, -89.4364

-0.86747, -89.43639 View on OpenStreetMap →

San Cristobal sits at -0.8675°N, 89.4364°W, on the coast of Galapagos Islands. 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.
