Weather in September

September, the first month of the spring in Sawohan, is also a hot month, with an average temperature varying between 24.4°C (75.9°F) and 31.7°C (89.1°F).

Temperature

With the onset of September, the average high-temperature registers at a still hot 31.7°C (89.1°F), subtly different from August's 30.8°C (87.4°F). An average low-temperature of 24.4°C (75.9°F) is common during the nights of September.

Heat index

The heat index value during September is appraised at a sweltering 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. 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 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

In September, the average relative humidity is 65%.
