Waimea Location

20.0231, -155.6717

20.02306, -155.67167 View on OpenStreetMap →

Waimea sits at 20.0231°N, 155.6717°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.
