Dense fog suddenly blanketed Nilphamari in northern Bangladesh early Wednesday, with dew-covered grass and a noticeable chill signalling the arrival of cooler weather after a prolonged spell of heat.
The district was shrouded in thick fog around 6AM, creating a markedly different atmosphere in the early morning.
Although daytime temperatures remain warm, with occasional rain and sunshine, residents said a mild chill has been noticeable after nightfall, particularly after midnight.
Locals said dense fog usually becomes more common toward the end of September, but this year it has appeared unusually early, in the middle of the month.
The fog reduced visibility on roads, forcing vehicles to travel with their headlights on. As sunlight strengthened later in the morning, the fog gradually began to clear.
Akram Ali, a resident of Nilphamari town, said, “I woke up in the morning to find the entire area covered in fog. Usually, the fog becomes denser toward the end of September, but this year it has appeared in the middle of the month.”
Alim Uddin, a rickshaw driver in the town, said he goes out with his vehicle early every morning. “Today, when I came out, I saw fog everywhere.''
Lokman Hakim, acting officer of the weather office at Saidpur Airport, said morning temperatures had fluctuated between 24°C and 26°C over the past few days.
''The minimum temperature recorded at 6AM today was 26.0°C. Temperatures will gradually fall further,'' he added.
