Weather in September
Temperature
September signals a slight drop in average high-temperature, sliding from August's tropical 31.6°C (88.9°F) to a warm 27.2°C (81°F). Throughout September, the average low-temperature in Tongbai dips to a refreshing 18.5°C (65.3°F).Heat index
The heat index value during September is computed to be 29°C (84.2°F). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
