Weather in December
Temperature
December's weather records an average high-temperature of a still tropical 31.7°C (89.1°F), showing little deviation from November. Throughout December, Palermo records an average temperature of 21.7°C (71.1°F) at night.Heat index
In December, the heat index is computed to be a scorching 40°C (104°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory.
