Heat index

December's mean heat index is estimated at a burning hot 47°C (116.6°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

The average relative humidity in December is 79%.

Remember, however, that not all shade structures offer full protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
