Average Temperatures by State 2022

Temperatures in the United States vary widely due to its large size and diverse topography. In fact, the country is home to some of the hottest places on earth, as well as its coldest. Parts of Alaska have an average monthly temperature below -10°F (-23°C) during the coldest months, while Death Valley averages over 115°F (46°C) in the summer. Of course, different parts of the country experience temperatures everywhere between these two extremes.

There are seven major climate zones in the United States. Generally, overall temperatures are warmer as one travels further south, while the air becomes drier as one moves further west until hitting the west coast. The Southwest region of the U.S. has many vast deserts and tends to have a hot, arid climate. The country's Southeast region has a sub-tropical climate characterized by hot, humid summers and mild winters. The Northwest fluctuates between bitterly cold winters and somewhat hot, humid summers. The West Coast experiences cool, wet winters and dry, warm summers. The Midwest has humid summers and harsh winters, especially in the northern states.

According to the National Oceanic and Atmospheric Administration, the United States experienced its fifth-hottest year on record in 2021, despite an arctic blast that plunged much of the south into abnormal freezing temperatures in February. The nation's average daytime highs reached 66.4°F (19.1°C), while average nighttime lows for the country were 42.6°F (5.9°C).
