Weather in September
September, the first month of the autumn in Delhi, is also a hot month, with an average temperature ranging between min 68°F (20°C) and max 86.9°F (30.5°C).Temperature
Delhi experiences a transition to a still tropical 86.9°F (30.5°C) in average high-temperatures with the arrival of September, not greatly differing from August's 90.5°F (32.5°C). In the month of September, Delhi records a consistent average low-temperature of 68°F (20°C).Heat index
For September, the heat index is estimated at a torrid 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
