Weather in September
Temperature
September, with average temperatures reaching a high of 29.6°C (85.3°F) and a low of 13.7°C (56.7°F), is the warmest month.Heat index
For September, the heat index is computed to be a tropical 30°C (86°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
