Weather in July
Temperature
The highest temperatures are recorded in July, with averages reaching a high of 91.9°F (33.3°C) and a low of 71.8°F (22.1°C).Heat index
July's mean heat index is evaluated at a blazing hot 116.6°F (47°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
