July weather forecast
Dallas, TX

Dallas in July signals peak summer with its highest annual temperatures, diminished precipitation, and ample sunshine. It becomes a hotspot for making the most of the prolonged sunlight hours, especially with wind speed dropping to the lowest level for the year. Rainfall declines further to July's 2.01" (51mm), with minimal precipitation and ample sun expected in the subsequent month. With outdoor activities abundant and cloud cover scant, sunbathers, hikers, and picnic enthusiasts can easily plan their trips. Despite July arguably being Dallas's hottest month, the lengthy daylight hours and moderate winds help to ameliorate the heat impact.

Temperature

July denotes a minimal variation in the average high-temperature to a sweltering 95.2°F (35.1°C) from June's 91.2°F (32.9°C). In the month of July, the temperature generally rests at an average low of 76.6°F (24.8°C).

Heat index

The average heat index in July is appraised at a burning hot 113°F (45°C). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

UV index

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the average person.
Note: A maximum high UV index of 7 in July translates into the following recommendations:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
