The average temperature in Death Valley last month was a stifling, suffocating 107.4 degrees. It was the hottest month ever recorded in the United States, and the second-hottest in the world — by just a fraction of a degree.

The average monthly temperature is a combination of highs and lows. Daytime temperatures in Death Valley are known to be excruciatingly hot...

But perhaps more alarming in this record is the month’s overnight temperatures — when things are supposed to cool down. The temperature didn’t fall below 89 degrees at any point in the month of July at Death Valley. On three nights, the “low” temperature was 102-103 degrees.
