Weather in September
Temperature
The introduction of September notes a subtle temperature variation to a still tropical 32°C (89.6°F) from August's 33.1°C (91.6°F). In September, the temperature drops to an average of 22.7°C (72.9°F) at night.Heat index
The heat index for September is computed to be a blistering 42°C (107.6°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
