Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still hot 32.9°C (91.2°F), closely aligned with August's 33.5°C (92.3°F). In Egmore, September nights witness a steady temperature drop to a moderately hot 26.9°C (80.4°F).Heat index
The heat index value during September is computed to be a scorching 43°C (109.4°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
