Waterville Location

51.8333, -10.1667

51.83333, -10.16667 View on OpenStreetMap →

Waterville sits at 51.8333°N, 10.1667°W, on the coast of County Kerry, 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.
