Weather in September
Temperature
Avery Island registers an average high-temperature of a still hot 86.7°F (30.4°C) with the arrival of September, showing minor deviation from the preceding month. During the nights in September, Avery Island experiences a consistent average temperature of 70.9°F (21.6°C).Heat index
For September, the heat index is calculated to be a torrid 102.2°F (39°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.For clarity, heat index numbers account for light winds and areas under shade. 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 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
