Weather in December
Temperature
Manzanillo's shift from November to December is accompanied by an average high-temperature of a still moderately hot 27.8°C (82°F), a slight deviation from 28.8°C (83.8°F). Recording a slight decline in temperature during the nights, Manzanillo's December temperatures average at a still moderately hot 25.9°C (78.6°F).Heat index
December's heat index is computed to be a tropical 31°C (87.8°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
