Information about the upcoming notable weather situation, according to Mr. Nguyen Huu Thanh - Deputy Head of the Weather Forecast Department, National Center for Hydro-Meteorological Forecasting, a widespread heat wave is about to appear in the North and Central regions.
Notably, this is not only the first widespread heat wave but also came earlier than the normal climate law.
The reason for this hot spell is that from March 29, the hot low pressure area in the west tends to develop and gradually expand eastward, the consequence is that the temperature will increase in many provinces and cities" - Mr. Thanh said.
Mr. Thanh provided detailed information, forecasting from about March 30 - April 2, the Northwest region and from Thanh Hoa to Hue city are likely to experience a widespread heat wave, with intense heat in some places with the highest daily temperature commonly 35 - 37 degrees C, locally over 38 degrees C.
From about March 30 - 31, the Northern Delta region is likely to experience widespread hot weather with the highest daily temperature commonly 35 - 36 degrees C, locally in some places above 36 degrees C.
The meteorological agency warns that the level of natural disaster risk due to hot weather is level 1. Due to the impact of hot weather combined with low humidity in the air, there is a risk of fires and explosions in residential areas due to increased electricity demand and the risk of forest fires. Hot weather can also cause dehydration, exhaustion, and heat stroke for the human body when exposed to high temperatures for a long time.
According to average statistics for many years, the first heat wave usually appears on the 2nd week of April. Thus, the first heat wave of this year comes about 10-15 days earlier" - Mr. Thanh analyzed.
The Deputy Head of the Weather Forecast Department said that this is a sign that the weather has had complicated developments right from the beginning of summer. With temperatures suddenly changing from cool to hot, the body is likely to find it difficult to adapt immediately.
People should avoid working outdoors and being exposed to direct sunlight for too long during peak heat hours from 12 - 16 pm daily; also need to supplement enough water and vitamins; pay special attention to the health of the elderly and children in the early days of the hot season" - Mr. Thanh advised.
The National Center for Hydro-Meteorological Forecasting said that in the context of global temperatures still maintaining at record highs, according to the World Meteorological Organization's warning, 2026 is likely to continue to be in the group of hottest years since the observation data was available.
When ENSO leans towards the hot phase from the second half of the year, monsoon winds in the Pacific Ocean tend to weaken, convection distribution changes, increasing the probability of prolonged and more extreme heat waves appearing in tropical areas, including Vietnam.
At the same time, rain in some Southeast Asian regions, especially in the south of our country at the end of the year, may be lower than the multi-year average.
