Weather in July
Temperature
The month of July, characterized by an average high of 91.6°F (33.1°C) and a low of 71.8°F (22.1°C), is recognized as the warmest.Heat index
The heat index in July is computed to be a blazing hot 113°F (45°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.For clarity, heat index numbers account for light winds and areas under shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
