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 Poso.

Poso Location

-1.3667, 120.7670

-1.36670, 120.76700 View on OpenStreetMap →

Poso sits at -1.3667°N, 120.7670°E, on the coast of Sulawesi Tengah, Indonesia. 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.
