Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 91°F (32.8°C) and a low of 72.7°F (22.6°C).Heat index
In July, the heat index is appraised at a life-threatening hot 114.8°F (46°C). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.Consider that heat index readings are for situations in the shade and light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', 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. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded.
