Weather in September
Temperature
During September, the average high-temperature is a still moderately hot 27.8°C (82°F), maintaining a close resemblance to that of the preceding month. An average low-temperature of 23.5°C (74.3°F), slightly less than the daytime peak, marks the month of September.Heat index
September's mean heat index is calculated to be a tropical 32°C (89.6°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
