Weather in July
Temperature
July proves to be the warmest month, recording an average peak temperature of 89.4°F (31.9°C) and a minimum temperature of 66.9°F (19.4°C).Heat index
July's average heat index is computed to be a blisteringly hot 104°F (40°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 of high significance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
