Navigating Monsoon Travel Risks in Bangladesh
The monsoon season in Bangladesh runs from June to October, bringing heavy rainfall that often leads to river overflows. While water-logging is a regular occurrence, the stagnant water left behind creates breeding grounds for Aedes mosquitoes, which transmit Dengue fever. Travelers should remain in air-conditioned accommodations where possible and wear long-sleeved clothing during peak mosquito activity hours (dawn and dusk).

Pro-Tip for Travelers: Stagnant water can disrupt local fixed line services. Keep your phone online to check weather advisories by activating a Bangladesh eSIM. It connects directly to local networks (Grameenphone or Robi) for reliable cellular data.
