Heat index

The heat index value during April is evaluated at an extremely hot 40°C (104°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. 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. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Take precautions against overexposure. Protection against sun damage is needed. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Attention! The combination of sand and water reflections enhances UV ray intensity.
