Weather in July
Temperature
July, with average temperatures reaching a high of 88.9°F (31.6°C) and a low of 67.6°F (19.8°C), is the warmest month.Heat index
In July, the heat index is estimated at an extremely hot 105.8°F (41°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.In terms of the heat index, values are set with light wind and shade conditions in mind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
