Rustico Location

46.4667, -63.2833

46.46670, -63.28330 View on OpenStreetMap →

Rustico sits at 46.4667°N, 63.2833°W, on the coast of Prince Edward Island, 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.
