The heat index value for December is appraised at a tropical 30°C (86°F). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.For clarity, heat index numbers account for light winds and areas under shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.

Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses. Heed this! UV intensity is much stronger when reflected off sand and water.
