What’s the warmest hour of the day?

Data is from Copernicus Data Store. It was processed and mapped in R.

This is a small section of a much larger project did on temperatures in the United States.

One thing I noticed after moving to Portland from LA was that it seemed to stay hotter much later in the afternoon. It bugged me for years until I finally made this map and proved my gut feeling right: on average, the hottest temperature of the day in Portland is at 5:30PM, and in LA it's just 4PM.

Another thing I love about this map are the small red blips scattered around the country: those are lakes, storing up heat throughout
