Temperature

The month of July, characterized by an average high of 85.8°F (29.9°C) and a low of 64°F (17.8°C), is recognized as the warmest.

Heat index

July's heat index is estimated at a torrid 95°F (35°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Consider that heat index readings are for situations in the shade and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
