For most parts of January, the heat index is evaluated at a tropical 30°C (86°F). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the importance of resting and drinking fluids.
