Weather in December
Temperature
December's climate shows a minor adjustment in average high-temperatures to a still warm 29.4°C (84.9°F) from November's 29.3°C (84.7°F). In December, the temperature drops to an average of 22.3°C (72.1°F) at night.Heat index
The heat index value during December is appraised at a very hot 36°C (96.8°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
