Weather in September
Temperature
September's commencement is accompanied by an average high-temperature of a still hot 31.9°C (89.4°F), diverging marginally from August's 32.5°C (90.5°F). In Sungai Lalang, in September, the average low-temperature is a moderately hot 23.5°C (74.3°F).Heat index
September's mean heat index is calculated to be a scorching 43°C (109.4°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 quite important for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
