Central Vietnam faces 6-day heatwave; El Niño to influence weather

Central Vietnam is bracing for a six-day heatwave, beginning July 18, with temperatures expected to range between 35 and 37 degrees Celsius, and potentially exceeding 37 degrees in some areas. The National Center for Hydro-Meteorological Forecasting issued a warning, advising residents to minimize outdoor activities during the peak heat hours of 12 PM to 4 PM.

Forecasters noted that while this heatwave is not predicted to be extremely severe, the combination of high temperatures and low humidity could impact public health. The affected areas include provinces from Nghe An to Da Nang, and the eastern parts of Quang Ngai to Khanh Hoa. The heatwave is expected to last until July 23, after which conditions are forecast to gradually cool.

Looking beyond the immediate forecast, the region's climate is under the influence of a strengthening El Niño. This phenomenon is projected to persist and potentially intensify through the end of 2027, significantly impacting weather patterns. El Niño's effects are expected to lead to generally higher temperatures across Vietnam compared to average years, with summer temperatures potentially 0.5-1.5 degrees Celsius higher and winter temperatures 1-2 degrees Celsius warmer.

Furthermore, El Niño is predicted to reduce the number of typhoons and tropical depressions in the East Sea compared to the multi-year average, with an estimated 8-10 storms, 3-5 of which may affect the mainland. However, forecasters caution that some storms could be powerful and follow complex, unpredictable paths. The forecast also indicates higher rainfall in some central regions in August, followed by potential rainfall deficits later in the year.
