Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a still hot 32.5°C (90.5°F), bearing a close resemblance to August. Throughout September, an average nighttime temperature of 25.8°C (78.4°F) is experienced.Heat index
The average heat index in September is estimated at a life-threatening hot 46°C (114.8°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. 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. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

In September, the rain falls for 24.3 days. Throughout September, 151mm (5.94") of precipitation is accumulated. In Potajia, Bangladesh, during the entire year, the rain falls for 163.4 days and collects up to 1023mm (40.28") of precipitation.Daylight

Sunshine

In September, the average daily maximum UV index is 7. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the ordinary person.Note: In September, the maximum UV index of 7 suggests these recommendations:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
