Weather in September
Temperature
September observes an average high-temperature of a still tropical 32.9°C (91.2°F), marking an insignificant difference from August's 33.5°C (92.3°F). During the nights in September, the temperature in Ambattur, India, averages to a moderately hot 26.9°C (80.4°F).Heat index
For September, the heat index is computed to be an extremely hot 43°C (109.4°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
