Dhaka experiences three distinct weather seasons: a hot and humid summer, a monsoon season with heavy rainfall, and a mild winter. During summer (March to May), temperatures can soar up to 35 °C (95 °F) or even higher, with high levels of humidity. The monsoon season (June to September) brings heavy rainfall, which cools down the temperature but increases humidity and brings the risk of flooding. Winter (October to February) is relatively mild with temperatures ranging between 10 °C to 25 °C (50 °F to 77 °F).
Compared to its region, Dhaka receives a significant amount of sun exposure due to its geographical location. With its proximity to the equator, the city experiences strong sunshine throughout the year. This higher sun exposure increases the risk of sunburn and heat-related illnesses. It is advised to stay hydrated, seek shade, and limit outdoor activities during peak sun hours to prevent sunburn and heat exhaustion.
