Weather in September
Temperature
The average temperatures reach their apex in September, averaging 27.5°C (81.5°F) at the high end and 14.5°C (58.1°F) at the low end.Heat index
The heat index for September is estimated at 29°C (84.2°F). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
