Weather in July
Temperature
July temperatures tend to peak at an average high of 90.9°F (32.7°C) and dip to a low of 71.2°F (21.8°C).Heat index
For most parts of July, the heat index is estimated at a blisteringly hot 111.2°F (44°C). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
