Heat index

For December, the heat index is estimated at a fiery hot 36°C (96.8°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
