Weather in July
Temperature
The shift into July finds Dennis at an average high-temperature of a still tropical 94.6°F (34.8°C), closely comparable to June's conditions. Throughout the month of July, Dennis reports a steady low-temperature average of 74.7°F (23.7°C).Heat index
For most parts of July, the heat index is calculated to be a scorching 111.2°F (44°C). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.Remember that heat index calculations are made for conditions in the shade with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Inhibit overexposure. Warding off sun damage is of utmost importance. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
