According to weather forecasts from the National Center for Hydro-Meteorological Forecasting, from about March 30 to April 2, the Northwest region and the strip from Thanh Hoa to Hue City are forecast to experience widespread hot weather, with the highest temperature commonly 35-37 degrees Celsius, locally over 38 degrees Celsius.
Meanwhile, from March 30-31, the Northern Delta region is also likely to record hot sun with the highest temperature commonly 35-36 degrees C, with some places exceeding 36 degrees C.
Hanoi weather forecast is the hottest on March 31, with the highest temperature reaching 36 degrees Celsius.
This is the first heat wave in 2026 in these areas and comes earlier than normal climate laws, potentially directly affecting summer travel plans.
In hot weather conditions combined with reduced air humidity, the risk of fires and explosions in residential areas and forest fires may increase, especially at natural destinations and mountains.
For tourists, prolonged high temperatures can cause dehydration, exhaustion or heat shock if traveling or sightseeing outdoors for a long time. Consider choosing destinations with cooler climates such as high mountains or coastal areas for the weekend.
With the risk level of natural disasters due to heat waves at level 1, this weather spell is not yet extreme but still needs to be closely monitored, especially in the context of the 2026 weather forecast having many unusual fluctuations.
