Temperature

July is the month that records the highest temperatures, with averages ranging from a high of 88.9°F (31.6°C) to a low of 69.4°F (20.8°C).

Heat index

During July, the heat index is calculated to be an extremely hot 105.8°F (41°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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 response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
