Weather in September

September, the last month of the rainy (monsoon) season in Dhaka, is also a hot month, with an average temperature varying between 25.5°C (77.9°F) and 33.3°C (91.9°F).

Temperature

September's onset sees an average high-temperature of a still tropical 33.3°C (91.9°F), exhibiting a slight fluctuation from the previous month. Dhaka records an average temperature drop to a warm 25.5°C (77.9°F) in September.

Heat index

For most parts of September, the heat index is computed to be a blazing hot 45°C (113°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
