Is Texas Humid?

Texas is home to both humid and arid climates, with humidity levels varying by location and season. In Rockwall, humidity can be an issue for much of the year, but especially in summer. Excessively moist air can make heat feel more oppressive, leaving you feeling sticky and uncomfortable.

Understanding Texas Humidity and Home Comfort

Both high and low humidity can impact your comfort, indoor air quality, and health. For example, when there is too much moisture in the air, your sweat cannot evaporate from your skin. This means your body cannot cool itself. Alternatively, dry air can give you dry skin and chapped lips. To keep your home comfortable, you must maintain proper humidity levels.

Why is Texas Humid?

Texas is especially humid in the eastern half of the state and along the coast. This is largely due to moist air coming from the Gulf of Mexico. Moisture levels can be affected by seasonal weather conditions, such as stalled weather fronts or high-pressure systems, that trap humidity. Rockwall’s lake humidity problem also contributes to moisture in our immediate area.

Texas Humidity Levels Throughout the Year

Rockwall, TX, and nearby areas generally experience higher humidity levels over the summer and somewhat drier air during winter. Coming in and out of your house, open windows or doors, or even gaps in insulation can circulate outdoor moisture into your home.

How Humid is Texas in the Summer?

One of the means by which humidity can be measured is by the dew point, which more accurately tells how humid it feels outside than relative humidity measurements. The higher the dew point, the more humid it feels. According to the National Weather Service, the dew point in the Dallas-Fort Worth area averages between 70.1 °F and 70.9 °F from June through August.

Although air conditioners can play a role in removing moisture from the air, they may not solve your humidity issues totally. Relative humidity levels of 60% and higher can strain HVAC systems, causing them to use more energy when cooling your home.

When Does the Humidity Go Down in Texas?

Texas typically has drier winters than summers, but humidity issues may persist indoors. Heating systems make the already dry air even drier, leading to a different sort of discomfort. Low humidity can affect your health by allowing airborne viruses and allergens to travel more easily, aggravating respiratory problems, or causing a scratchy throat. For this reason, it is important to have a year-round humidity control solution.

How Humid is Rockwall, Texas?

Although Rockwall is very close to DFW, the nearby lake can raise ambient humidity levels in our area. Rockwall temperature and humidity both play a factor in how comfortable you feel. Local residents must be particularly mindful of how humidity can affect mold growth, allergens, and overall indoor air quality. Increased humidity can also damage wood floors and wood furniture, and increase energy use for your AC.

Rockwall, TX Temperature and Its Impact on Indoor Humidity

Hot air has a greater capacity to hold water vapor, allowing higher humidity levels during the summer. While your HVAC system can cool warm air or heat cold air, temperature control is not the same as humidity control. You need a system that specifically removes or adds moisture to your home’s air to affect humidity.
