The average heat index in December is estimated at a tropical 30°C (86°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
