Weather in December
Temperature
The ushering in of December brings an average high-temperature of a warm 29.7°C (85.5°F), closely mirroring the 30.5°C (86.9°F) of November. During December, the temperature is averaged to a low of 19.7°C (67.5°F) at night.Heat index
December's mean heat index is appraised at a tropical 33°C (91.4°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
