September weather forecast
Seremban, Malaysia

September introduces a dip in the temperature curve, relieving Seremban somewhat from its perpetual steaminess. Despite showing slightly lower rainfall at 61mm (2.4"), the cloud cover maintains a stout presence in the sky. Sunlit hours decline slightly, casting slightly longer shadows. Mild gusts of wind rustle through the foliage, their cool whispers lending a soothing undertone to the otherwise balmy conditions. As the year progresses, September gracefully adapts to the gradual climatic transitions.

Temperature

Seremban's transition from August to September introduces an average high-temperature of a still hot 31°C (87.8°F), identical to the previous month. The low-temperature average for Seremban during September stands at a moderately hot 23.6°C (74.5°F).

Heat index

September's average heat index is evaluated at a blistering 40°C (104°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Be watchful! The reflection of snow can enhance the intensity of the Sun's UV radiation nearly double.
