Weather in September
Temperature
The advent of September presents an average high-temperature of a still warm 27.3°C (81.1°F), maintaining a close correlation with the preceding month. September sees the temperature falling to a mean low of 18.8°C (65.8°F).Heat index
September's average heat index is estimated at a tropical 31°C (87.8°F). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
