Weather Forecasting: Cold Front to Hit Northern Region from April 22 Night
Weather forecasting now points to a late-season cold spell moving into northern Vietnam from the night of April 22, bringing cooler air, rain and thunderstorms after a stretch of intense heat. The Department of Dike Management and Disaster Prevention under the Ministry of Agriculture and Environment said the cold air mass will first affect the northeastern region before spreading to the Northwest and North-Central areas. The National Center for Hydro-Meteorological Forecasting said the system is moving southward and will broaden its influence over the following days.
Cooler Air Moves In After Intense Heat
From April 23, the northeast and Thanh Hoa are expected to turn cooler, with minimum temperatures of 21–24 degrees Celsius and below 20 degrees Celsius in mountainous areas. In Hanoi, scattered showers and thunderstorms are forecast from the night of April 22 to April 23, followed by cooler conditions with lows of 22–24 degrees Celsius. Meteorological agencies also warn of localized heavy rain across the North during the evening of April 22 to April 23.
Before the cold air arrives, much of the North and Central regions remain hot. On April 22, the Central region is forecast to reach peak heat of 36–38 degrees Celsius, with some areas above 38 degrees Celsius. The northwest and areas from Da Nang to Dak Lak may see highs of 35–37 degrees Celsius. The colder air will be felt more clearly in Hanoi, the Red River Delta and the North-Central region from April 23 as temperatures fall and the heat eases.
Weather Forecasting Shows Rain, Storms, and Strong Winds
The National Center for Hydro-Meteorological Forecasting said showers and thunderstorms may extend beyond the North into the North-Central and Central regions in the following days. Thunderstorms may bring lightning, hail and strong gusts. At sea, the northern Gulf of Tonkin is expected to see strong northeast winds at level 5–6, with gusts up to level 7 and waves of 1. 5–2. 5 meters.
In a separate outlook, the National Centre for Hydro-Meteorological Forecasting said northern Vietnam will continue seeing frequent thunderstorms through the end of April 2026 because of a low-pressure trough and successive weak cold air masses. That weather forecasting outlook also points to no widespread heatwaves in the North during this period.
Officials Urge Close Watch as Conditions Shift
Weather forecasting for April 20 to April 22 shows a brief break in the North after scattered showers and thunderstorms, but another round is expected from the night of April 22 to April 24. Hanoi may see dry weather on April 21–22 with light southeast winds and temperatures rising slightly to 31–32 degrees Celsius before storms return later in the month.
Weather forecasting for central Vietnam also shows a quick turn from heat to storms, with scattered thunderstorms likely from April 23–25, especially from Quang Tri to Hue. Meteorological authorities said the country is entering a seasonal transition period, when shifting air masses raise the risk of whirlwinds, lightning, hail and strong gusts, especially after intense heat.
Residents are being urged to monitor developments closely and take precautions for both people and property as the cold spell, rain and thunderstorms move through the region. Weather forecasting remains focused on the next several days, when the sharp shift from heat to cooler conditions may become more widespread across northern Vietnam.
