Death Valley, California, is among the hottest places, if not the hottest place, on earth. On July 10, 1913, the mercury hit 134.1°F, or 56.7°C. Since that is about the same time that a permanent weather station was established, the record keeping is viewed with some skepticism, but imaging living in there, and being put in charge of the weather station! There was nothing automatic about it. You would have to go outside twice a day to record the low and high temperature, look at the thermometer, and write down the temperatures in a log book. Today, the records have been entered into databases, notably in the Global Historical Climate Network or land weather stations. Ironically, the name of the weather station is “Greenland Ranch,” which is a place that is now more appropriately called Furnace Creek.

Head on over to the charting tool to build your own interactive chart! Run filters on the data, download the data, and view the chart in other ways, such as in the form of a heatmap or a contour chart. The contour chart can be quite revealing about local climate trends!

The bigger the screen you have, the better, and even though it does take a minute for the chart to load, it is well worth it.
