Heat index

In January, the heat index is computed to be a tropical 31°C (87.8°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.

Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
