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 Puntarenas.

Puntarenas Location

9.9778, -84.8294

9.97784, -84.82942 View on OpenStreetMap →

Puntarenas sits at 9.9778°N, 84.8294°W, on the coast of Costa Rica. 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.
