Weather in July
Temperature
Rowlett's shift into July sets the average high-temperature at a still hot 94.3°F (34.6°C), a figure that deviates only slightly from June's 90.1°F (32.3°C). Throughout July, Rowlett anticipates an average low-temperature of 75°F (23.9°C).Heat index
The heat index value during July is estimated at a blazing hot 114.8°F (46°C). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
