Vietnam has experienced significant weather disruptions, characterized by intense heat in the north and tidal flooding risks in the south. In late October, northern regions faced an unusual heatwave driven by El Niño and subtropical high-pressure systems, while southern areas like Ho Chi Minh City were warned of tidal peaks expected to exceed Alarm Level 3.

By early November, meteorological data confirmed that Vietnam recorded its hottest October since observations began in 1961. The national average temperature was 1.74 degrees Celsius above the historical average. The northern region experienced the most severe anomalies, with 69 stations recording their highest historical average monthly temperatures and some locations reaching as high as 38.3 degrees Celsius.
