Coney Island Location

52.7111, -9.0069

52.71111, -9.00694 View on OpenStreetMap →

Coney Island sits at 52.7111°N, 9.0069°W, on the coast of County Clare, Ireland. 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.
