Weather in December
Temperature
December notes an average high-temperature of a moderately hot 29.8°C (85.6°F), subtly differing from November's 30°C (86°F). Nighttime temperature experiences an average drop to a pleasant 21.2°C (70.2°F) in December.Heat index
The heat index for December is appraised at a very hot 37°C (98.6°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
