Weather in December
Temperature
December welcomes an average high-temperature of a still warm 29.5°C (85.1°F), not much different from the preceding month. During December, Cabo Blanco records a consistent average nighttime temperature of 22.3°C (72.1°F).Heat index
For December, the heat index is appraised at a sweltering 35°C (95°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Note that heat index values are valued for light wind and location in the shade. 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', comes about by integrating the temperature readings with the humidity levels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
