Fremont Location

37.5485, -121.9886

37.54854, -121.98858 View on OpenStreetMap →

Fremont sits at 37.5485°N, 121.9886°W, on the coast of California, United States. 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.
