La Romaine Location

50.2167, -60.6833

50.21670, -60.68330 View on OpenStreetMap →

La Romaine sits at 50.2167°N, 60.6833°W, on the coast of Québec, Canada. 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.
