July temperatures tend to peak at an average high of 91°F (32.8°C) and dip to a low of 73.2°F (22.9°C).Heat index
For most parts of July, the heat index is computed to be a life-threatening hot 113°F (45°C). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
