Beihai Location

21.4813, 109.1202

21.48129, 109.12016 View on OpenStreetMap →

Beihai sits at 21.4813°N, 109.1202°E, on the coast of China. 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.
