Weather in September

Temperature

As September takes its course, Kulai's average high-temperature registers at a still tropical 31.6°C (88.9°F), closely aligning with the preceding month. The mean low-temperature during September nights is a moderately hot 24.1°C (75.4°F).

Heat index

Throughout September, the heat index is appraised at a blistering 41°C (105.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
