The line running through the bars is the daily average over those 10 years, so you can see the typical shape of the month at West Island.

West Island Location

-15.5333, 136.5500

-15.53330, 136.55000 View on OpenStreetMap →

West Island sits at -15.5333°N, 136.5500°E, on the coast of Northern Territory, Australia. 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.
