Weather in September
Temperature
September's advent notes a subtle adjustment in average high-temperature to a still hot 86.5°F (30.3°C) from August. September nights in Kenner are marked by an average temperature drop to a moderately hot 75°F (23.9°C).Heat index
For September, the heat index is computed to be a very hot 98.6°F (37°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
