How Hot Does it Get in Dallas During Summer?
Summer in Dallas is known for its scorching temperatures, providing a sharp contrast to the more temperate climate experienced during other parts of the year. Average temperatures in July and August hover around 96°F (36°C) during the day, with nighttime lows typically ranging from 77°F (25°C) to 80°F (27°C). This heat is often accompanied by high humidity, which can significantly enhance the sensation of heat.
It is not uncommon for temperatures to soar well above 100°F (38°C) during the summer months, especially during heatwaves. These extreme conditions can lead to dangerous heat index values that can feel well over 100°F (38°C). For instance, in 1980, 2011, 2022, and 2023, Dallas experienced particularly hot and dry summers characterized by prolonged periods of intense heat. During these rare yet significant heatwaves, the temperature can climb to record highs, sometimes even surpassing 105°F (40.5°C).
Summer Temperature Patterns
During the summer months of June, July, and August, Dallas experiences a range of temperatures from the mid-80s to the high 90s Fahrenheit (35-40°C). The month of July typically brings the hottest weather, with daily temperatures often exceeding 96°F (36°C). In August and September, it is quite common for temperatures to hit the triple digits. While relief does arrive in the fall, it usually comes just in time for the State Fair of Texas.
The combination of high temperatures and high humidity in Dallas can make the heat feel even more intense, often referred to as the heat index. This is a measure of how the humidity and heat combine to affect the human body. High humidity can significantly increase the perceived temperature, making it feel much hotter than the actual temperature reading.
