Weather in September
Temperature
The arrival of September sees an average high-temperature of a still hot 32.2°C (90°F), hardly diverging from August's 32.4°C (90.3°F). The nighttime temperature in Hulu Yam Lama, during September, averages of 23.2°C (73.8°F).Heat index
September's average heat index is calculated to be an extremely hot 43°C (109.4°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Note that heat index values are valued for light wind and location in the shade. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
