Weather in September
Temperature
The arrival of September marks a slight shift to an average high-temperature of a still tropical 33.6°C (92.5°F) from August's 32.8°C (91°F). Sampit records an average nighttime low-temperature of 22.7°C (72.9°F) throughout September.Heat index
Throughout September, the heat index is evaluated at a life-threatening hot 47°C (116.6°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are essentially critical for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Remember, however, that not all shade structures offer full protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
