Weather in July
Temperature
July, having an average high-temperature of 89.1°F (31.7°C) and an average low-temperature of 69.6°F (20.9°C), is the warmest month.Heat index
In July, the average heat index is evaluated at a blisteringly hot 105.8°F (41°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Records show heat index calculations are tailored for shaded regions and mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

A UV Index of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for the average person.Note: The daily high UV index of 6 during July translates into the following recommendations:
Take precautions against overexposure. Protection against sun damage is needed. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
