A decline in average rainfall, humidity and relative wind speeds characterizes the weather in Jessore during September. Moreover, the number of daylight hours and sunlight begin to dwindle. A decrease in cloud cover compared to the previous months is perceived. September's transition from monsoon to drier conditions often brings fluctuating weather conditions.

Temperature

Jessore's average high-temperature in September is a still tropical 31.9°C (89.4°F), marking an insignificant difference from the 32.3°C (90.1°F) of August. Throughout the month of September, Jessore witnesses an average low-temperature of 25.5°C (77.9°F).

Heat index

September's mean heat index is appraised at a burning hot 45°C (113°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
