This week’s concern centers on coastal backflow moving into three key river systems: the Chao Phraya River high tide, Tha Chin River high tide, and Mae Klong River high tide zones. The risk tends to spike for a few hours around the daily high tide, then ease as the tide falls. Practical commuter advice stays the same across Bangkok-area high tide events:Add extra travel time, especially if the route includes underpasses. For related context on recent high tide warnings, see Bangkok Post coverage of earlier January high tide warnings. ConclusionThe Thailand high tide alert for Jan 31 to Feb 4 is a practical warning, not a prediction of disaster.
