Weather in September
Temperature
With September's arrival, Taniwel notes an average high-temperature of a still moderately hot 27.5°C (81.5°F), closely following the trend of the preceding month. Taniwel welcomes an average low temperature of 23.9°C (75°F) in September, a gentle shift from the day's high.Heat index
The heat index value for September is evaluated at a tropical 31°C (87.8°F). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
