The summer of 2023 in Vietnam is expected to come early and the heat will be more intense than the summer of 2022. The phase change from La Nina to El Nino in the summer of this year will dominate and affect Vietnam's weather.
According to experts, it is forecasted that April, May, and June this year will be approximately 1 degree Celsius hotter than the average of many years. Normally, a heat wave will take place for about 3-5 days, however, this year may be longer, for about 5-7 days, especially in the Central region, the number could be even longer. The main reason for this is that the ocean-atmospheric state (ENSO) is changing to a neutral phase.
In April, the heat has already been more severe with higher intensity nationwide, including in the North, Central and South. In particular, the peak of heat will be in June-July in the North and from the second half of June to August in the Central region with a high probability of intense and especially intense heat. In May and June, the South will expect a drop in temperature, however, in the North and Central Vietnam, the weather will still be hot and the heat can last until early August in the North and late August in the Central region.
Regarding storms and tropical depressions, the number of tropical cyclones in the East Sea and affecting Vietnam is likely to be lower than the average of many years (on average, annually, there are about 12-13 storms in the East Sea and 5-6 storms affecting land).
In the months of the rainy and stormy season, in the Northern region, the rainfall tends to be lower to approximately the average of many years, and the possibility of heavy rain at the end of May and the beginning of June in the North like 2022 is low. In the Central region, the rainfall tends to be approximately higher than the average in the period of July-September 2023. However, from October to December 2023 (the main time of the rainy season in Central Vietnam), the rainfall tends to be less than the average of many years in this area, and the trend of lack of rain may persist into early 2024.
