Southeast Asia is currently experiencing unusually intense monsoon conditions, with nearly a week of torrential rains causing significant congestion at the region's major container ports - Singapore and Port Klang.

According to Linerlytica's latest report, both Singapore and Port Klang are now facing vessel delays of up to three days.

Singapore, the world's second-largest container port and busiest transshipment hub, is currently experiencing moderate congestion levels as assessed by Lloyd's List Intelligence SeaSearcher. The port currently hosts 329 vessels, with 170 arriving today. EconDB data shows affected ships include CMA CGM's 15,254 TEU Galapagos and COSCO's 4,253 TEU Haifa.

Port Klang has similarly been rated with moderate congestion by SeaSearcher, with 77 vessels currently at anchor at the Malaysian port.

This marks the third major monsoon surge in 2025 so far - an unusual weather pattern as Southeast Asian monsoons typically peak earlier during the December-January northeast monsoon season. On average, the region experiences up to four monsoon surges annually, each lasting between one to five days.

On March 19, Singapore's Maritime and Port Authority (MPA) issued an advisory urging vessel operators to exercise caution during the monsoon surge period. The MPA emphasized that ships must maintain proper safety protocols at sea given forecasts of heavy showers and strong winds.
