Heat index

During July, the heat index is estimated at a blistering 44°C (111.2°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
Data suggests that the heat index is set for environments in shade and with a light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Take precautions against overexposure. Protection against sun damage is needed. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Attention! The combination of sand and water reflections enhances UV ray intensity.
