Weather in July
Temperature
July is the warmest month, exhibiting average temperatures of 91.8°F (33.2°C) at the peak and 72.1°F (22.3°C) at the base.Heat index
The heat index in July is calculated to be a blazing hot 114.8°F (46°C). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

The months with the highest UV index are July and August, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.Note: The UV index of 7 during July translates into the following guidance:
Resist extreme sun exposure. Guarding against solar damage is essential. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
