Throughout December, the heat index is appraised at a tropical 31°C (87.8°F). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
