If you’re short on time, here’s a quick answer to your question: Yes, Texas gets hot and humid in the summer, especially in the eastern half of the state. Humidity levels are highest in Houston and the Gulf Coast region.

In this comprehensive 3000 word guide, we’ll break down humidity levels across Texas. We’ll look at which cities and regions get the most muggy conditions. We’ll explore humidity variation from summer to winter. And we’ll discuss how climate change could impact Texas humidity going forward.

Regional Variation in Texas Humidity

When it comes to humidity in Texas, there is no one-size-fits-all answer. The Lone Star State is known for its diverse climate, with varying levels of humidity across different regions. Understanding these regional variations can help you plan your activities and make the most out of your time in Texas.

Gulf Coast and East Texas – Most Humid

If you find yourself on the Gulf Coast or in East Texas, be prepared for some serious humidity. These regions experience the highest levels of humidity in the state. The warm waters of the Gulf of Mexico contribute to the moisture in the air, creating a muggy and sticky environment.

Summers in this area can be particularly challenging, with high humidity levels making the temperature feel even hotter. If you’re planning outdoor activities in these areas, make sure to stay hydrated and take breaks to avoid heat exhaustion.

South Texas – Moderate Humidity

Heading further south in Texas, you’ll encounter a more moderate level of humidity. The cities of San Antonio, Corpus Christi, and Brownsville experience humidity levels that are not as extreme as those found on the Gulf Coast, but still noticeable.

This moderate humidity can make the summer months feel quite warm, but not overwhelmingly stifling. It’s still essential to stay hydrated and protect yourself from the sun, but you may find it slightly more comfortable compared to the Gulf Coast and East Texas regions.

West Texas – Low Humidity

As you move towards West Texas, you’ll notice a significant drop in humidity levels. Cities like El Paso and Midland experience relatively low humidity throughout the year. This can be a welcome relief for those who prefer drier climates.

The lack of moisture in the air can make the temperature feel more bearable, even during the hot summer months. However, it’s important to keep in mind that low humidity levels can also lead to dehydration, so it’s still crucial to stay hydrated and take precautions when spending time outdoors.

Understanding the regional variation in Texas humidity can help you plan your activities and dress appropriately for the weather. Whether you find yourself in the muggy Gulf Coast, the moderately humid South Texas, or the dry West Texas, it’s always a good idea to check the local weather forecast before heading out.

Stay prepared, stay hydrated, and make the most out of your time in the great state of Texas!

Seasonal Differences in Humidity

Hot, Humid Summers

The summer season in Texas is well-known for its hot and humid weather conditions. As temperatures rise, so does the level of humidity in the air. The combination of high temperatures and humidity can make summers in Texas feel quite uncomfortable.

The humidity levels during this time of year can often reach above 80%, creating a sticky and muggy atmosphere. This high humidity can affect both indoor and outdoor environments, making it important to find ways to stay cool and comfortable.

During the summer months, it is not uncommon for Texans to rely on air conditioning systems to combat the heat and humidity. These systems help to regulate indoor humidity levels and create a more comfortable living environment.

Additionally, using dehumidifiers can also be beneficial in reducing excess moisture in the air.

For those who enjoy outdoor activities, it is important to stay hydrated and take breaks in shaded areas to prevent overheating. Wearing light and breathable clothing can also help to minimize discomfort caused by the humidity.

It’s no wonder that many Texans flock to the nearest swimming pool or beach to cool off during the summer months!

Mild, Less Humid Winters

While summers in Texas can be hot and humid, winters bring relief from the intense humidity. The winter season in Texas typically experiences milder temperatures and lower humidity levels. This combination creates a more comfortable and pleasant environment for residents.

During the winter months, people in Texas can enjoy spending time outdoors without feeling weighed down by the humidity. It’s the perfect time to go for hikes, bike rides, or simply enjoy a leisurely walk in the park.

The lower humidity levels also make it easier for the body to regulate its temperature, allowing for a more enjoyable outdoor experience.

Indoor environments during the winter season also benefit from the lower humidity levels. The drier air can help prevent the growth of mold and mildew, which thrive in moist conditions. However, it’s important to strike a balance to avoid excessively dry air that can lead to dry skin and respiratory discomfort.

Using a humidifier can help add moisture to the indoor air and maintain a comfortable humidity level.

Record Humidity Levels and Historical Events

Wet Bulb Temperature Records

Texas is known for having some oppressively humid days, especially in the summer. To measure humidity levels, meteorologists use wet bulb temperature readings. This factors in ambient temperature, humidity, and wind speeds.

Some staggeringly high wet bulb temperatures have been recorded in the Lone Star State:

  • The highest wet bulb temperature ever measured worldwide was 90°F in Dhahran, Saudi Arabia in 2003.
  • Texas reached an extreme wet bulb temperature of 86°F in Apple Springs in 2000.
  • Wet bulb temperatures over 80°F are considered dangerous to humans.

Studies show that due to climate change, peak wet bulb temperatures are increasing in Texas during the summer months when humidity levels are at their highest. This puts Texans at greater risk of heat-related illnesses on sweltering, muggy days.

Notable High Humidity Events

Texas has endured some memorably humid periods throughout history when soupy air covered the state:

  • In June and July of 2011, Texas saw 70 consecutive days with high humidity and temperatures above 100°F, straining power grids.
  • The humid summer of 1993 was so oppressive it came to be known as the “Summer of Sweat.”
  • In 1980, a historic heat wave combined with high humidity created dangerously hot conditions across Texas.

When humidity levels exceed 70% in Texas, conditions start feeling sticky, muggy, and downright uncomfortable. Now we know why most homes and businesses blast the A/C during Texas summers!

Future Outlook for Texas Humidity and Climate Change

Climate change has been a topic of concern for scientists and policymakers around the world. As global temperatures continue to rise, the effects of climate change are becoming increasingly evident, and one of the areas that will be significantly impacted is humidity levels in different regions.

Texas, known for its hot and dry climate, may experience changes in its humidity levels in the coming years.

Potential For More Muggy Heat Waves

With rising temperatures, Texas could see an increase in the frequency and intensity of muggy heat waves. These heatwaves can be particularly uncomfortable as high humidity levels make it harder for sweat to evaporate, leaving individuals feeling sticky and uncomfortable.

The combination of high temperatures and high humidity can also pose health risks, especially for vulnerable populations such as the elderly and those with respiratory conditions.

According to a study published in the Nature Communications journal, researchers found that in the future, heatwaves in Texas could become more frequent and longer-lasting due to climate change. The study predicts that by the end of the century, the number of heatwave days in Texas could increase by up to 150%.

This increase in heatwaves, coupled with higher humidity levels, could have significant implications for the well-being of Texans.

Impacts on Health and Agriculture

The combination of heat and humidity can have adverse effects on human health. Heat-related illnesses, such as heat exhaustion and heatstroke, can become more prevalent as humidity levels rise. Additionally, high humidity can exacerbate respiratory conditions, such as asthma, making it more difficult for individuals to breathe comfortably.

Furthermore, the agricultural sector in Texas may also face challenges due to changes in humidity levels. Crops that are sensitive to high humidity, such as certain fruits and vegetables, may struggle to thrive in a more humid climate.

Increased humidity can also create favorable conditions for the growth of pests and diseases, posing a threat to crop yields and agricultural productivity.

Adaptation and mitigation measures will be crucial in addressing the potential impacts of increased humidity in Texas. These measures could include improving heat resilience in infrastructure, implementing heat emergency response plans, and implementing sustainable agricultural practices that can withstand changing climatic conditions.


While west Texas experiences generally dry conditions, eastern regions like Houston see hot, sticky summers with average humidity over 60-70% or higher. Gulf moisture fuels muggy weather and thunderstorms across the eastern half of the state.

As temperatures rise in the future, climate models project an increase in extreme heat events. Texas could see more frequent heat waves pairing life-threatening temperatures with high humidity.
