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 Hamada.

Hamada Location

34.9000, 132.0670

34.90000, 132.06700 View on OpenStreetMap →

Hamada sits at 34.9000°N, 132.0670°E, on the coast of Shimane, Japan. 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.
