Guadalupe Island Location

29.0525, -118.2761

29.05252, -118.27605 View on OpenStreetMap →

Guadalupe Island sits at 29.0525°N, 118.2761°W, on the coast of Baja California, 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.
