Why Does Halong Bay Experience Extremely High Rainfall Throughout the Year?

💡 The Answer

• Halong Bay lies in a tropical monsoon climate zone with a distinct wet season from May to October.
• Warm, moist air from the South China Sea brings heavy rainfall when it meets the coastal mountains.
• Annual precipitation averages around 2,000 to 2,200 millimeters, with frequent thunderstorms.
• The high rainfall accelerates the erosion of limestone, continuously shaping the bay's karst landscape.
