Weather in September
Temperature
Temperature readings reach their annual highs in September, averaging 27.3°C (81.1°F) and a minimum average of 19.6°C (67.3°F).Heat index
The heat index in September is computed to be a tropical 31°C (87.8°F). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
