Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a warm 85.1°F (29.5°C), from a not significantly different 87.6°F (30.9°C). Pointe à la Hache in September observes a slight diminution in temperature from daily highs, recording a low-temperature average of 77.7°F (25.4°C).Heat index
The heat index value during September is evaluated at a torrid 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
