Weather in July
Temperature

The heat index in July is appraised at a sweltering 96.8°F (36°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
