Greystones Location

53.1491, -6.0793

53.14912, -6.07934 View on OpenStreetMap →

Greystones sits at 53.1491°N, 6.0793°W, on the coast of 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.
