May weather forecast
Bangladesh

May is characterized by hot and humid conditions in Bangladesh as it marks the end of the pre-monsoon season. Average daytime temperatures can reach highs between 32°C (89.6°F) and 38°C (100.4°F), and nighttime temperatures seldom fall below 25°C (77°F). Regions in the north, like Rajshahi and Rangpur, may see slightly cooler nighttime temperatures.

In the cities of Dhaka and Chittagong, the heat intensifies further. Dhaka sees temperatures ranging from 27°C (80.6°F) to 36°C (96.8°F), while Chittagong, with its coastal influence, experiences a range of 26°C (78.8°F) to 34°C (93.2°F). The heat, combined with high humidity levels, can make the weather seem particularly oppressive.

May sees a dramatic surge in rainfall compared to April, with an average precipitation of about 250mm (9.84"), indicating the imminent arrival of the monsoon season in June. This heavy rainfall, coupled with occasional thunderstorms, can cause disruption in daily activities and travel.

Despite the challenging weather conditions, the lush green landscapes resulting from the increased rainfall can be visually appealing. However, visitors must be prepared for the subsequent month of June, which marks the beginning of the monsoon season, characterized by even higher rainfall and persistent humidity.
