July's average heat index is computed to be a very hot 100.4°F (38°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high.

Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
