Weather in December
Temperature
The onset of December notes an average high-temperature of a still tropical 32.5°C (90.5°F), subtly shifted from November's 34.3°C (93.7°F). Antanimbary's nights in December cool down to an average low-temperature of 24.4°C (75.9°F).Heat index
December's mean heat index is evaluated at a blisteringly hot 41°C (105.8°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

A UV Index estimate of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for the average person.Note: In December, the maximum UV index of 7 suggests these recommendations:
Deflect overexposure. Sun protection is a necessity. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. To cut down UV radiation exposure by about half, sport a wide-brim hat.
