Heat index

The heat index value for December is calculated to be a blistering 40°C (104°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
