Heat index

December's heat index is calculated to be a torrid 39°C (102.2°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

The average relative humidity in December is 83%.

Deter overexposure. Protecting against the sun's effects is essential. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
