Weather in September
Temperature
A subtle shift in Grand Cane's weather is observed as August turns into September, with the average high temperature reducing from a torrid 95°F (35°C) to a hot 88.9°F (31.6°C). The average temperature during September nights is registered at an enjoyable 67.6°F (19.8°C).Heat index
During September, the heat index is estimated at a blistering 104°F (40°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
