The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children.
