Dry Heat vs Humid Heat and Which States Have What

Certain days will be intolerable due to varying weather conditions combined with warmer months throughout the year. It would be helpful to know that there are several kinds of heat throughout these warmer months. It can assist someone in understanding how to avoid overheating at this time of year and to remain cool. It’s critical to take into consideration that a person’s body will react differently to heat depending on the temperature and relative humidity.

Dry heat and humid heat are the two primary categories of heat. Most desert climates are dry, but humid heat is seen on the east coast of the United States, where precipitation from the Gulf Coast moves northward. Humid heat occurs when relative humidity levels are more than 30%, whereas dry heat occurs when they are at or below 30%.

What is Dry Heat?

When the temperature is above 90 degrees and the humidity is 30 percent or lower, the result is dry heat. Desert climates are generally where this kind of heat happens. Low humidity, which gauges the amount of water vapour in the air, results in dry heat. Places like Las Vegas or Phoenix that receive minimal rainfall are more vulnerable to dry heat because rainfall affects humidity levels. Since the body can expel more heat through perspiration, dry heat often does not “feel” as hot as humid heat. In dry air, moisture from your breath and saliva will also evaporate quickly, leaving you with an uncomfortable “dry mouth,” in addition to sweat evaporating off your skin quickly and carrying additional heat with it.

What is Humid Heat?

High temperatures and high air moisture content combine to produce humid heat. This is the area with temperatures at or above 90 °F and at least 30% relative humidity. High temperatures and high air moisture content produce humid heat. As a result, sweat does not evaporate as quickly, which hinders the body’s ability to cool down. Because of this, it may “feel” hotter than it would in a dry environment.

Which States Experience Dry Heat?

Many residents will tell you, “But it’s a dry heat,” adding that they much prefer this to humid climates. The majority of these individuals reside in lowlands, desert regions, and other locations where rain falls infrequently. In some of these locations, it can still become rather hot, but at least the temperature usually seems accurate. There isn’t much estimation or computation involved in predicting the weather. What makes a state or an area arid? Low precipitation averages are the result of the climate’s lack of moisture, which occurs when precipitation falls less than evaporation.

Throughout the year, dry heat is experienced in several places.

New Mexico

New Mexico receives only about 13 inches of rain annually on average. Mountains, desert, and high plains make up the majority of the state. New Mexico, one of the driest states in the union, receives less than one inch of precipitation every month.


This state, which is among the driest in the nation, is located in the Sierra Nevada Mountain range. This occurs as a result of the mountain’s wider variety of elevations and ability to keep moisture out of the Pacific Ocean.


The Grand Canyon State receives only about 15 inches of precipitation on average year. Depending on your location, the heat index changes across the state. People enjoy a much hotter summer down in the valley, surrounded by mountains, whereas the summer up north is around 20 degrees colder. All of the various locations are still experiencing dry heat, though.


The southwest region of the nation is home to many of the driest states. Here, 17 inches of rain fall on average each year. Utah’s climate ranges from desert to semi-arid, with scorching summer temperatures and very frigid winters.


Another state that is located in the country’s mountain areas is Wyoming. People who live there or visit do so in higher extremes of temperature. The least amount of rainfall ever measured was between five and eight inches.


Only about 20 inches of rain fall on Montana annually on average. Montana experiences frequent droughts because of its location and high temperatures. Montana, one of the driest states in the union, has almost 40% of its land covered in drought.

What States Have Humid Heat?

There are several states in the nation where the heat is quite muggy. This is because of several of these states’ geographic location and proximity to big bodies of water. The warm, humid air from the Gulf of Mexico causes significant amounts of moisture in states that are close to it. The quantity of precipitation that these states receive annually is another important aspect. The most humid states are found in the Southeastern region of the United States, which has a subtropical climate with hot, muggy summers.


Mississippi has one of the highest humidity levels in the nation, with an approximate humidity of 88%. This is because of the climate and location of the state. Extremely high humidity is caused by a mixture of warm seas from being so close to the Gulf of Mexico, strong winds, and a lot of rainfall.


Louisiana’s proximity to the Gulf of Mexico contributes to the state’s humidity. But Louisiana’s bayous, swamps, and coastal marshes serve as moisture sinks, adding to the humid atmosphere.


Another state that is close to the Gulf of Mexico is this one. The third-most humid state in the union is Alabama. Alabama’s high humidity is further influenced by the state’s abundance of rivers and lakes as well as its heavy rains.


Florida has an average humidity of 85%, which is extremely humid. Florida’s wetland ecosystem, including the Everglades, is crucial to preserving the state’s humid climate. The state’s general humidity is influenced by its tropical and subtropical climate, which also includes high temperatures and frequent downpours.


Another state that is near the Atlantic Ocean and the Gulf of Mexico is Georgia. The state as a whole has extremely high humidity as a result. Georgia’s terrain, which includes both mountains and coastal plains, contributes to the state’s uneven humidity levels.


Arkansas, a state in the Southeast of the United States, has varying temperatures throughout the year, with an average humidity of 85%. It has to do with the state’s closeness to the Gulf of Mexico, just like it does for other states on this list. The addition of rivers, mountains, and forests simply increases the amount of moisture in the air, increasing humidity.
