Weather in September
Temperature
The arrival of September brings an average high-temperature of a still warm 27.1°C (80.8°F), nearly identical to August's 25.5°C (77.9°F). September is noted for a mean low-temperature of 19.3°C (66.7°F).Heat index
For most parts of September, the heat index is appraised at 29°C (84.2°F). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for 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.
