Weather in September
Temperature
September's arrival brings an average high-temperature of a still hot 34.4°C (93.9°F), slightly deviating from August's 34°C (93.2°F). Throughout September, an average nighttime temperature of 25.5°C (77.9°F) is experienced.Heat index
The heat index value during September is computed to be a blazing hot 48°C (118.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
