Weather in September
Temperature
September indicates a minor shift in the average high-temperature, from August's tropical 31.3°C (88.3°F) to a warm 27.2°C (81°F). During the nights in September, the temperature averages to a pleasant 21.3°C (70.3°F).Heat index
The heat index in September is computed to be 29°C (84.2°F). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 hold particular importance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
