September is marked by an average high-temperature of a still warm 27.5°C (81.5°F), almost identical to the preceding month. In September, the nighttime temperature lowers to an average of 17.5°C (63.5°F).Heat index
September's average heat index is estimated at a hot 31°C (87.8°F). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
