I can attest to the fact that the weather here in Dallas can be quite unpredictable. One day it might be scorching hot with barely a cloud in the sky, while the next day can bring thunderstorms and torrential downpours. 

But one thing that seems to be a constant source of discomfort for many is the humidity. Whether you’re a lifelong Dallasite or just visiting for the first time, the question “Is Dallas humid?” is bound to come up sooner or later. 

In this article, we’ll delve into the truth about Dallas’s humidity levels, including why Dallas tends to be so humid and what the average humidity is for this city. 

So grab a glass of iced tea and let’s dive in! 

Is Dallas humid or dry?

Dallas has a semi-arid climate that’s neither completely humid nor dry. It’s hot and dry in the summer with low humidity, and cool or mild in the winter.

The average relative humidity ranges from 56% in the morning to 37% in the afternoon. 

As someone who has lived in Dallas for several years now, I can tell you that the weather here is unpredictable and can change daily. In the summer, temperatures can soar to the triple digits, and the air can feel like a hot, sticky blanket. 

However, the humidity levels are not as high as in some other parts of the United States, making the heat more bearable. 

During the winter months, the weather can be quite mild, with temperatures rarely dropping below freezing. However, there are occasional cold snaps that can bring snow and ice to the area. 

The winter climate in Dallas is relatively dry, making it a popular destination for those looking to escape the harsh winters of other regions. 

According to data from the National Oceanic and Atmospheric Administration (NOAA), the average relative humidity in Dallas ranges from 56% in the morning to 37% in the afternoon. 

This means that while the air may feel dry, it still contains enough moisture to prevent it from being considered a completely dry climate.

One thing to note about Dallas is that it is prone to droughts, particularly during the summer months. The lack of rainfall can cause the soil to dry out, leading to increased wildfire risk and water restrictions. 

It’s important to keep this in mind when planning outdoor activities during the summer.

Why is Dallas so humid? 

Dallas is humid due to its location in North Texas, warm climate, and proximity to the Gulf of Mexico, which produces moisture. Human activity also contributes to the high humidity levels. 

Dallas is located in North Texas, which is part of the southern United States. This region is known for its warm and humid climate, especially during the summer months. 

This is because warm air can hold more moisture than cool air, so as the temperature rises, so does the humidity.

Another factor that contributes to Dallas’ humidity is its proximity to the Gulf of Mexico. The Gulf is a large body of water that produces a lot of moisture, which can be carried northward by prevailing winds. 

When these moist air masses collide with the hot air over Texas, it creates the perfect recipe for humid conditions.

Finally, human activity also plays a role in Dallas’ humidity levels. As a large metropolitan area with millions of people, Dallas has a lot of cars, factories, and other sources of pollution that can contribute to the humidity. 

This is because many of these sources release water vapor into the air, which can add to the already high levels of moisture.

How humid does it get in Dallas? 

Dallas can get incredibly humid, with an average humidity level of around 70% during the summer months. 

In July, one of the hottest months of the year, temperatures can soar to an average high of 96 degrees Fahrenheit (35 Celsius), with lows around 76 degrees Fahrenheit (24 Celsius). 

Summer in Dallas, which typically spans from May to September, can bring high levels of humidity. On average, the humidity level during this season hovers around 70%, which can make the already scorching temperatures feel even hotter. 

In fact, in July, one of the hottest months of the year, the combination of high heat and humidity can make it feel like the temperature is in the triple digits.

While the humidity in Dallas can be uncomfortable, it’s important to remember that it can also have health implications. High humidity levels can cause a person to sweat profusely, leading to dehydration and heat exhaustion. 

Additionally, high humidity can exacerbate respiratory issues such as asthma and allergies.

To combat the humidity, Dallas residents often turn to air conditioning. In fact, during the hottest months of the year, it’s common to see people huddled indoors, seeking refuge from the heat and humidity. 

Many businesses and public places have also adapted to the climate, providing air conditioning and shaded areas to make staying outside more bearable.

What is the most humid month in Dallas? 

The most humid month in Dallas is August, with average relative humidity levels reaching as high as 75%.

According to data from the National Oceanic and Atmospheric Administration (NOAA), the average relative humidity in Dallas is around 60% throughout the summer.

While the humidity in Dallas is generally high throughout the summer months, August tends to be the most humid. 

This is due in part to the fact that August is typically one of the hottest months of the year in Dallas, with average high temperatures in the mid-90s Fahrenheit. 

The high humidity levels can make it feel even hotter and can also contribute to increased levels of discomfort for those who are not accustomed to the heat and humidity.
