Heat index

July's average heat index is evaluated at a life-threatening hot 113°F (45°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. 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. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
