Weather in September
Temperature
With the start of September, Gebeng measures an average high-temperature of a still hot 30.5°C (86.9°F), not significantly differing from August's 30.9°C (87.6°F). During the nights of September, the average low-temperature in Gebeng holds at a warm 25.5°C (77.9°F).Heat index
September's average heat index is computed to be a torrid 39°C (102.2°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
