Introduction
The U.S. is a large country, stretching across an entire continent and even a little beyond. As such, it is home to multiple weather phenomena and varying temperatures across the 50 states.
The U.S has several different climate zones which affect the average temperatures of states as well as the effects of the seasons. If you go from north to south, you would find that the temperature gradually increases. If you go from east to west, one would notice that the air gradually gets drier until you hit the arid plains and deserts along the west coast, beyond the rocky mountains. These temperature patterns can be explained by proximity to the equator or by geographic features/topography.
The highest recorded temperature in the U.S. was 134F in Death Valley, California. This is due to the arid nature of the region as well as the effects of climate change. However, this result by itself doesn’t make California the hottest state in the U.S. The average temperatures of a state are measured by tabulating recorded temperatures over a period of time.
To see which states rank highest and lowest in average temperatures, take a look at the data in the charts.
