September's heat index is evaluated at a hot 86°F (30°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face greater risks than adults as their sweat production is less.
