Throughout January, the heat index is calculated to be a tropical 31°C (87.8°F). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
