Weather in September

September welcomes a transition away from the sweltering summer to the advent of autumn. The temperature begins to dip, making way for the forthcoming cooler months. Correspondingly, the rainfall dwindles down to 120mm (4.72"), falling over fewer days than the preceding months. Despite the winds slowing down to an average speed of 8.9km/h (5.5mph), September continues to relish the extended daylight hours and high UV index. Consequently, the weather paves the way for a pleasant and enjoyable atmosphere.

Temperature

Maoming's average high-temperature marks a still hot 31.3°C (88.3°F) with the advent of September, closely mirroring that of the preceding month. An average low-temperature of 24.4°C (75.9°F) is noted during the month of September.

Heat index

The heat index for September is appraised at a blistering 42°C (107.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
