Paia Location

20.9033, -156.3694

20.90333, -156.36944 View on OpenStreetMap →

Paia sits at 20.9033°N, 156.3694°W, on the coast of Hawaii, United States. 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.
