Weather in September
Temperature
Acuminca commences September with an average high-temperature of a hot 30.9°C, maintaining a close resemblance to the previous month. In the month of September, Acuminca witnesses a consistent average low-temperature of 24.7°C.Heat index
The heat index value during September is evaluated at an extremely hot 41°C. Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
