Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
