Welcome to my blog about driest states in the US!
Climate change is expected to make the southwestern US even drier in the future. This is due to a number of factors, including the region’s location in the lee of the Sierra Nevada mountains, which block moisture from the Pacific Ocean from reaching the southwest. Further reasons are the region’s distance from the Gulf of Mexico, which is a source of moisture for other parts of the country and the region’s general lack of rainfall.
The southwest of the US is located in the so-called “rain shadow” of the Sierra Nevada and Rocky Mountains. These mountain ranges block moisture-laden air masses from reaching the southwest, resulting in less rainfall. Additionally, the southwest is located in a subtropical high pressure zone, which inhibits the development of rain-producing storms.
As the planet warms, the subtropical high pressure zone is projected to expand northward, further inhibiting the development of storms and leading to even less rainfall. Additionally, warmer temperatures will lead to more evaporation, which will further decrease the amount of water available in the region. These changes will put additional stress on already scarce water resources in the southwest, and will likely have a negative impact on agriculture in the region.
So let’s get started and enjoy the article about driest states in the US!
13 Driest States in the US
The 13 driest states in the US are:
1. Arizona
With an average of only 12 inches of rain per year, Arizona is the first state in our list of the driest states in the US (not the driest state overall). The state’s low rainfall is due to its location in the rain shadow of the Sierra Nevada and Cascade mountain ranges. The driest part of Arizona is the southwestern corner of the state, which receives less than 8 inches of rain per year.

57 | Sterling | 15.2 | 387 |
72 | Trinidad | 14.9 | 378 |
4. Idaho
Idaho’s dry climate is caused by its location in the rain shadow of the Cascade Mountains. The state receives very little precipitation, and what does fall is often quickly evaporated or absorbed by the dry, sandy soil. This lack of moisture means that Idaho is particularly vulnerable to drought. The effects of climate change are expected to make Idaho’s dry conditions even worse.
Warmer temperatures will lead to more evaporation, and changes in precipitation patterns will result in less rainfall. These conditions will put stress on agriculture and water resources, and could lead to more frequent and longer droughts. Idaho’s dry conditions are already having an impact on its residents.
The state has been experiencing an increased number of wildfires in recent years, and the lack of moisture is making it difficult for farmers to irrigate their crops. With climate change expected to make Idaho even drier, these problems are only expected to get worse.

5. Montana
Montana is one of the driest states in the US. Climate change is expected to make it even drier and warmer in the future. Changes in temperature and precipitation will adversely affect agriculture. And they will contribute to more frequent and longer droughts, putting additional strain on existing water supplies in this part of the country.
Montana’s climate is already arid, with an average of only 16 inches (41 cm) of precipitation per year. Most of this precipitation falls as snow in the mountains, while the rest of the state receives less than 10 inches (25 cm) of rain or snow each year. This lack of moisture, combined with high summer temperatures, makes Montana one of the driest states in the country. Climate change is expected to worsen these conditions.
Average temperatures in Montana are projected to increase by 2-4 degrees Fahrenheit (1-2 degrees Celsius) by the middle of this century, with even higher temperatures possible in the future. This warming will cause more evaporation and reduce the amount of moisture available for precipitation. At the same time, the jet stream is expected to shift northwards in response to Arctic warming. This could bring drier conditions to Montana and other parts of the Northern Plains.
Warmer temperatures will lengthen the growing season, but the lack of moisture will make it difficult for crops to thrive. The state’s water supplies will also be under strain, as demand increases during dry periods.

Nevada is the number one in our list of the driest states in the US, with an average of only 11 inches of rain per year. Most of the state’s rain falls in the mountains, while the western and southern parts of the state are much drier. The driest part of Nevada is the southern tip of the state, which receives less than 5 inches of rain per year.

8. North Dakota
The state’s average annual precipitation is only 16.8 inches (427 mm), and much of that falls as snow. The state’s low humidity levels and high winds contribute to evaporation, leaving little moisture for plants to grow. The state’s climate is changing, however, and that is likely to make the situation worse.
According to some climatologists, climate change will make this area considerably drier and warmer in the future. Temperature and rainfall changes will negatively influence agriculture and contribute to more frequent and lengthier droughts, putting additional demand on existing water supplies in this part of the country. The state’s population is growing, too, which will only increase the demand for water.
North Dakota’s farmers and ranchers are among the most efficient in the country, but they will be hard-pressed to maintain that level of efficiency in the face of a drier climate. The state’s water resources are already under stress. The Ogallala Aquifer, which supplies water to much of the state, is being depleted at an alarming rate. And many of the state’s lakes and streams are contaminated with agricultural chemicals. If the state’s water resources are not managed carefully, the situation could become dire. North Dakota’s leaders need to start planning now for a future with less water.

10. South Dakota
We expect climate change to intensify these trends. Projections suggest the state will warm by an additional 3-5 degrees Fahrenheit by the century’s end, and the rainfall is likely to decrease by a further 5-10 percent. These changes will make it even more difficult to grow crops and could lead to even more frequent and severe droughts. The state’s water resources will be under even more pressure as a result. South Dakota is already taking steps to adapt to the changing climate.
The state has developed a statewide water plan that includes strategies for increasing water efficiency, developing new water sources, and managing drought. But it will be a challenge to meet the state’s water needs in the future as the climate continues to change.

12. Utah
Utah’s climate is already arid, and the state receives very little rainfall. The average annual precipitation in Utah is only about 12 inches (30 cm), and much of the state receives even less than that. Because of this, Utah is particularly vulnerable to drought. Droughts are expected to become more frequent and more intense in the future as the climate continues to change. This will put a strain on water supplies, as well as on the agricultural industry. Crops will suffer from the lack of water, and farmers will have to find ways to irrigate their fields.
The state of Utah is already taking steps to prepare for the impacts of climate change. The state has created a Drought Task Force to develop plans for dealing with drought conditions. The Task Force is working on a statewide water conservation plan, as well as on ways to improve water efficiency. Utah is also working to increase its water storage capacity. The state is currently in the process of building a new reservoir, the Bear River development, which will help to meet the state’s future water needs.
Despite these efforts, Utah is still expected to face significant challenges in the future due to climate change. The state will need to continue to find ways to conserve water and to improve its water efficiency.

What state is the driest state in the US?
The driest state in the US is Nevada. There are several reasons for this. First, the state is located in the Great Basin, which is a large area of land that is surrounded by mountains. This geographical feature means that there is very little rainfall in Nevada. Second, the state has a lot of desert land. Deserts are dry areas where there is very little rainfall. Finally, Nevada is a very sunny state. This means that there is less moisture in the air, which leads to less rainfall. These factors make it difficult for vegetation to grow and for water to be available, making it the driest state in the US.
What state has the driest city in the US?
The most dried city in the United States is Yuma, Arizona. Yuma has an arid climate, which means that it receives very little rainfall each year. The city averages only about 3 inches of rain per year, and it often experiences long periods of drought. The dry climate is due to the city’s location in the Sonoran Desert. The desert is a large area of land that receives very little rainfall. The dry climate of Yuma makes it the perfect place for growing crops that require little water, such as cotton and hay. However, the dry climate also makes the city vulnerable to wildfires.
Is Colorado drier than California?
According to climatologists, climate change will make Colorado considerably drier and warmer in the future. Temperature and rainfall changes will negatively influence agriculture and contribute to more frequent and lengthier droughts, putting additional demand on existing water supplies in this part of the country.
Colorado is drier than California for a few reasons. One reason is that Colorado is located in the interior of the country, while California is located on the coast. This means that Colorado is less influenced by moist air from the Pacific Ocean, and thus tends to be drier overall. Additionally, the Rocky Mountains act as a barrier, preventing moisture from moving east into Colorado from the wetter states to the west.
What are the driest areas in the US?
According to some climatologists, climate change will make the southwestern United States considerably drier and warmer in the future. Temperature and rainfall changes will negatively influence agriculture and contribute to more frequent and lengthier droughts, putting additional demand on existing water supplies in this part of the country.
The southwestern United States ranks among the country’s driest regions, and we expect climate change to dry it even further. Rising temperatures will drive the soil’s water to evaporate, and we anticipate less rainfall in this region going forward. These changes will put stress on agriculture and water supplies, and could lead to more frequent and severe droughts.
The western United States is also one of the driest areas in the country. The region experiences little rainfall and high temperatures, which can lead to droughts. These conditions negatively impact agriculture and put additional demand on water supplies.
What states have the least humidity?
The states with the least humidity are Arizona, New Mexico, and Colorado. These states are all located in the southwestern United States, which is expected to see drier and warmer conditions in the future due to climate change.
Arizona has an average humidity of only 30%, making it the driest state in the country. New Mexico and Colorado are not far behind, with average humidity levels of 32% and 34%, respectively.
The low humidity in these states is due to their location in the desert. The dry, warm air in the desert does not hold much moisture, leading to very low humidity levels.
The low humidity levels in the southwestern United States are expected to worsen as climate change causes the region to become drier and warmer. This will put additional strain on water supplies in the area and make it even harder for agriculture to thrive.
Summary – Driest States in the US
According to some climatologists, climate change will make the area around the United States significantly drier and warmer in the future. Changes in temperature and precipitation will adversely affect agriculture. They will also contribute to more frequent and longer droughts, putting additional strain on existing water supplies in this part of the country. This will cause problems for agriculture and could lead to water shortages in the future.
