Weather in July
Temperature
The shift to July signals an average high-temperature of a still hot 94.8°F (34.9°C), subtly varied from June's 90.9°F (32.7°C). Duncanville's average low-temperature for the month of July records at a warm 76.5°F (24.7°C).Heat index
The average heat index in July is appraised at a burning hot 114.8°F (46°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
