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.

Heat index

The heat index value during July is computed to be a blazing hot 113°F (45°C). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
