July turned out to be an exceptional month of triple threats for the western U.S., with record heat, drought and raging wildfires. The nation as a whole had a hot July—with extreme rainfall in areas already saturated while sparing others that needed it most.

Here's a climate snapshot of the month of July and the year to date, according to scientists from NOAA's National Centers for Environmental Information:

Climate by the numbers, July 2021

The average temperature last month across the contiguous U.S. was 75.5 degrees F (1.9 degrees above average), placing July 2021 in the 13th-warmest spot in the 127-year .

California, Nevada, Oregon and Washington had their hottest Julys on record. Five other states—Idaho, Montana, North Dakota, Utah and Wyoming—saw their top-10 hottest Julys.

The average precipitation for last month was 3.36 inches (0.58 of an inch above average), making it the sixth-wettest July on record. Precipitation was above average across much of the Northeast, Southeast and South, as well as portions of the Midwest, Ohio Valley and Great Lakes. New York and Massachusetts had their wettest July on record.

Meanwhile, much of the Northwest and Northern Tier, as well as parts of the central Plains, Midwest and central Appalachians, had below-average precipitation. Minnesota and Washington saw their second- and fourth-driest July on record, respectively.
