The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children.
