Heat index

In December, the average heat index is computed to be an extremely hot 40°C (104°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

In December, the average relative humidity is 67%.
