Temperature
September's climate shows a minor adjustment in average high-temperatures to a still tropical 31.3°C (88.3°F) from August's 31.7°C (89.1°F). Hiramandalam notes a consistent average low-temperature of 26.4°C (79.5°F) during September nights.Heat index
The heat index in September is calculated to be an extremely hot 41°C (105.8°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
