Throughout December, Mulifanua reports a steady low-temperature average of 27.5°C (81.5°F), slightly lower than its daytime counterpart.Heat index
The heat index value during December is appraised at a tropical 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
