September weather forecast

An increase in sunshine hours to 8.4 per day also marks a departure from the monsoon-influenced climate of previous months. The dip in temperature and reduced humidity in the atmosphere make the weather more comfortable. The declining trend of water vapor density contributes to noticeably clearer skies, bringing relief to the residents from the persistent cloudy scenario of the past months. The resuming wind speed averaging 14.3km/h (8.9mph), ensures calm and pleasant days, ideal for outdoor exploration.

Heat index

Throughout September, the heat index is computed to be a torrid 38°C (100.4°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
