French Bay Location

-43.8087, 172.9590

-43.80873, 172.95898 View on OpenStreetMap →

French Bay sits at -43.8087°N, 172.9590°E, on the coast of Canterbury, New Zealand. 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.
