Weather in July
Temperature
With an average high-temperature of 89.6°F (32°C) and an average low-temperature of 73°F (22.8°C), July is the warmest month.Heat index
During July, the heat index is calculated to be a blistering 109.4°F (43°C). Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Deflect overexposure. Sun protection is a necessity. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
