Weather in July
Temperature
The arrival of July brings an average high-temperature of a still tropical 91.4°F (33°C), closely following the temperature pattern of June. Nighttime temperatures in July average to a warm 74.8°F (23.8°C).Heat index
For July, the heat index is appraised at a life-threatening hot 114.8°F (46°C). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. 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. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Take precautions against overexposure. Protection against sun damage is needed.

Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
