Weather in September
Temperature
September begins with an average high-temperature of a still tropical 31.4°C (88.5°F), reflecting close similarity to the preceding month. Yumbi reports an average low-temperature of 22.7°C (72.9°F) during the nights of September.Heat index
The heat index value for September is computed to be a blisteringly hot 40°C (104°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
