Weather in July
Temperature
The warmest month is July, with an average high-temperature of 94.3°F (34.6°C) and an average low-temperature of 73°F (22.8°C).Heat index
In July, the average heat index is estimated at a blazing hot 122°F (50°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. 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. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Sunshine

The months with the highest UV index are May through August, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for average individuals.Note: A daily high UV index of 7 in July leads to these guidelines:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
