For most parts of January, the heat index is computed to be a hot 30°C (86°F). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat.
