Top 10 Most Humid States of US in 2023

Humidity is the most complex atmosphere trait and significant weather and climate influence. In the atmosphere and environment, ambient water vapor plays a significant part. Humidity is the water vapor content in the air known as humid air’s moisture. By absorbing thermal radiation from the sun, the Earth influences air temperature and contributes to precipitation.

Rain data show humidity as a percentage of the air’s maximum water vapor, also known as relative humidity. Its correspondence temperature determines the humidity potential of the air. An amount of air will retain less vapor of water as the temperatures fall.

When the air is hot, sweat cannot evaporate and makes our body moist and wet. Our bodies must work harder to reset, inducing unnecessary sweating, pulse rate increases, ventilation increases, blood circulation, and depth.

In general, the temperature of the air will feel cooler than it is by humidity. Exterior will feel like a strain in states with extremely hot summers and high humidity. Because humidity is the water vapor content in the air, and the water vapor originates from water evaporation from Earth’s surface.

1. What is America’s least moist state?

Nevada (38.30 percent )

2. Can 100 humidity kill you?

No, it’s unlikely. 100% humid indicates that the air is saturated with water vapor at the specified temperature.

3. Is humidity possible by 0 percent?

The idea of zero percent signifies air without water vapor, but it is impossible because of Earth’s atmosphere and atmospheric conditions. Water steam, though only trace quantities, is still present in the air.

Given this, the most humid states in the United States are a mix of warm, southern states and cold, northern states.


Relative Humidity:77.1%
Average Precipitation days:105.5
Average Sunny days:126

Average temperatures and rainfall for several years are decisive for the atmosphere in Alaska. The extratropical storm path passes along the Chain of the Aleutian Islands, the Alaskan Peninsula, and the coastal Gulf of Alaska, where a vast number of storms cross through the North pacific reveal these sections of the government. Alaska’s climate is better described as humid.

The highest and the lowest measured temperatures in Alaska exist in the interior and are a good example of a true subarctic climate. The climate in far northern Alaska is arctic, with long, snowy winters and mild summers, with year-round snow. The Alaskan interior climate is best characterized as intense and a strong illustration of a real subarctic continental climate.


Relative Humidity:74.5%
Average Precipitation days:104
Average Sunny days:205

Florida’s climate is humid subtropical in the northern and central regions of America. The warm climate is mostly in South Florida. The rainy season is established from May to October when heavy yet brief summer rainfall falls in the daytime. In October, much of the dry season continues throughout Florida until late April. Florida can get seriously dry in mid-to-late winter. In a few years, the dry season is very severe, and water management limits are enforced.

While most Florida parts do not suffer from freezing ice, often, a decade north, Florida will see fleeting snow or sleet. The climate system is humid subtropical for certain parts of the county, while parts of South East Florida’s Gold Coast and all Florida keys are tropical wet, and dry. About 2,400 and 2,800 hours of sunshine a year present in a narrow eastern portion of Orlando and Jacksonville state.

3. Louisiana

Relative Humidity:74%
Average Precipitation days:109.2
Average Sunny days:216

The climate in Louisiana is subtropical and natural because of the Gulf of Mexico. Continental weather trends also influence the state since it is situated at the mouth of the wide river valley of Mississippi-Missouri, about halfway between the Atlantic and the Pacific Oceans. In the next decades, Louisiana can grow colder, and both flooding and droughts will become more serious. By way of comparison to the rest of the country in the last century, Louisiana was not colder.

However, the soil has become drier, and the annual rainfall has increased, the strong drainage of the rain and the sea level has increased. Our warming environment will lead to more flood destruction, less crop production, and harmful fisheries, more sick hot days, and a higher risk of heated stroke and other heat-related diseases.

Due to a loss of the shores, Louisiana, shifting environmental conditions that will not make coastal wetland habitats easily inhabitable, and deteriorating industries’ economic viability in this region, is anticipated to be the site of a significant climate refugee problem and overall makes the humid environment in all over the area.

4. Mississippi

Relative Humidity:73.6%
Average Precipitation days:100.4
Average Sunny days:216
Mississippi River

Mississippi environment lies in the subtropical wet, temperate winters; long, hot summers; rainfall spread reasonably uniformly across the year. During the coming decades, Mississippi may grow colder, and flooding and drought both more extreme. South winds will be prevailing and provide humidity and future misery for the period from May to September. Contrary to other people, in the last 50 to 100 years, Mississippi has not been colder.

However, the soil has gotten drier, yearly rainfall has increased, and the sea level increases by about 1 inch every seven years. The warming atmosphere is expected to lead to more tropical storms, fewer crop yields, harmful animals, higher unpleasantly hot days, higher risk of hot stroke and other hot diseases.

5. Hawaii

Relative Humidity:73.3%
Average Precipitation days:194.9
Average Sunny days:271

The state of Hawaii, covering the Hawaiian Islands, is tropical but has varying temperatures, depending on the altitude and the environment. As a result of orographic precipitation, the islands produce the most precipitation from the trade winds on their northern and eastern (wind side). Coastal areas, especially on the south and west or on leeward sides, are drier. The rainy season coincides with the winter months, and Hawaii is different from many tropical places with the marked dry and wet season.

Windy regions appear to be more humid in the summer, as there is a greater incidence of trade winds and accompanying clouds. In contrast, less gloomy zones, which are more influenced by trade clouds, are more cluttered in the winter, as stormy fronts travel more regularly.

6. Iowa

Relative Humidity:72.4%
Average Precipitation days:108
Average Sunny days:200

Iowa has a humid, hot, and cold continental climate all over the world. Heat and humidity are famous in Iowa Summers, often at temperatures of almost 90°F (32°C) and sometimes above100°F (38°C). In the north-west region of the state and the lower part of the 20s F (about -6 ° C), winters are cold at January’s normal temperatures of about 14° F (−10 °C). Climate changes would probably increase the incidence of Iowa flooding.

Rainfall has grown by about 35% during the four wettest days of the year, and the volume of water in most lakes has risen by over 20% during the worst floods of the year. Spring rainfall and annual precipitation are likely to rise in the next century, and heavy precipitation is likely to worsen. Any of these variables raises the flood risk more.

7. Michigan

Relative Humidity:72.1%
Average Precipitation days:130.5
Average Sunny days:170

Michigan is a humid continental climate with a strong distinction of the precipitation during the year in summers and winters. The average Detroit temperature ranges between 24.5°C in January and 73.5°C in July. More than 11,000 lakes are 5 acres or greater in the State of Michigan. Michigan is more vulnerable to floods because of too much water in the province. “Climate change is projected to increase the occurrence of Michigan flooding.

The total annual precipitation has risen 5 to 10 percent over the last half-century in much of the midwest. However, rainfall rose by around 35 percent over the four wettest days of the year. Spring precipitation, annual precipitation, and extreme rainstorms will certainly rise, and moisture will increase over the next century.

8. Indiana

Relative Humidity:72%
Average Precipitation days:129
Average Sunny days:186
Indiana Dunes

In the state’s central regions, Indiana is subject to a humid continental climate and the southern subtropical climate. Hot summers and cold winters are common, with temperature in the southern regions steadily increased. Indiana had a humid continental atmosphere, cool winters, and warm moist summers. The wet, subtropical climate, which receives more rain than other Indian regions, lies only in its extreme southern portion.

After the 2016 upgrade, about half of the country is now classed as wet subtropical. Temperatures are usually different from the North and the south. While droughts often happen in the state, total rainfall is spread over the year reasonably evenly. Snow with the humidity and relative temperature of Michigan lake upwind is around half that in north-West and North Central Indiana. The average velocity of the wind is 13 km/h.

9. Vermont

Relative Humidity:71.7%
Average Precipitation days:170
Average Sunny days:167
Vermont Fall

Vermont is humid continental and has mild snowy summers and winters. Vermont’s state government has recorded a substantial rise in precipitation in the past 50 years, increased storms and floods, and causes a winter colder and shorter. These developments have important consequences on both the winter tourism market and the decrease in critically important agriculture and timber sectors, such as maple sugar—the consequences of climate change attributable to human-made changes in the atmosphere.

The state is now seeing the effect on its ecosystems, economy, and public health of climate change. Vermont’s state government has recorded a substantial rise in precipitation in the past 50 years, increased storms and floods, and is winter colder and shorter.

1. Maine

Relative Humidity:71.7%
Average Precipitation days:131.4
Average Sunny days:192

Maine’s climate is humid with warm summers and often hot and long cold winters. Spring arrives early in the United States’ north-east, with more snow, stronger rainstorms, and cooler and drier summers. The sea level rises, and extreme storms cause floods which harm property and infrastructure more and more. The intensity of both flooding and droughts is expected to increase with increasing temperatures and evolving rainfall patterns.

In winter and spring, the average precipitation is more likely to rise but not dramatically in summer or autumn. In spring, the temperatures are expected to melt the snow, thus eliminating the soil’s evaporation in summer and fall. Therefore, winter and spring rains are expected to worsen, and summer and fall droughts are worse, and moisture is up by 71.1%.


It is easy to believe that Florida or Louisiana is the wettest state in the USA since both states are relatively mild with almost massive water bodies. Now, however, as we can see from the list, Alaska is the wettest territory. The explanation is that moisture is a fraction of the overall amount of water that air can retain at a certain temperature with relative moisture. The weather contains less water vapor as temperatures drop. As a result, relative humidity in cold regions can be much higher even if average air humidity is less prevalent.
