Weather in July
Temperature
July, known for its average high temperature of 90.1°F (32.3°C) and an average low temperature of 74.5°F (23.6°C), is the warmest month.Heat index
Throughout July, the heat index is computed to be a blazing hot 113°F (45°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: In July, the maximum UV index of 7 translates into these guidelines:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
