Weather in July
Temperature
July's onset sees an average high-temperature of a still very hot 97.7°F (36.5°C), exhibiting a slight fluctuation from the previous month. During the month of July, an average temperature of 76.3°F (24.6°C) is noted during the nights.Heat index
For July, the heat index is appraised at a life-threatening hot 118.4°F (48°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
