Weather in September
Temperature
Fevre, Haiti, notes an average high-temperature of a still moderately hot 29.2°C (84.6°F) in September, displaying minor variation from August. Fevre observes a minimal variance in temperature, with a consistent average low of 26°C (78.8°F) during the nights of September.Heat index
The heat index value for September is computed to be a sweltering 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
