Heat index

For most parts of December, the heat index is calculated to be a blistering 43°C (109.4°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Consider that heat index readings are for situations in the shade and light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

In December, the average relative humidity is 67%.

Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
