Widespread hot weather across central Vietnam is expected to ease on August 19, as reported by the National Centre for Hydro-Meteorological Forecasting. The forecast for August 18 indicates that temperatures in regions from Quang Tri to Danang, as well as eastern areas from Quang Ngai to Dak Lak and Khanh Hoa, will range between 35-36 degrees Celsius, with some locations exceeding 36 degrees. Humidity levels are predicted to be around 55-60 percent.

Forecasters have warned that actual outdoor temperatures could be 1-3 degrees higher than the predicted figures, particularly over surfaces like concrete and asphalt. This combination of high temperatures and low humidity increases the risk of fires, especially as electricity demand rises. Prolonged exposure to the heat could lead to dehydration.

Health experts recommend that individuals limit outdoor activities between 10 am and 4 pm, avoid strenuous exercise during hot conditions, and ensure adequate hydration. The elderly, children, and individuals with underlying health conditions are advised to take extra precautions.

As of August 17, the hot weather has been affecting the northern midlands and plains, as well as areas from Thanh Hoa to Danang and eastern parts from Quang Ngai to Dak Lak and Khanh Hoa. Temperatures at 1 p.m. on that day ranged from 35-37 degrees Celsius, with some locations reporting even higher temperatures. For instance, Con Cuong in Nghe An recorded 37.8 degrees, Danang reached 37.7 degrees, Hoi Xuan in Thanh Hoa hit 37.4 degrees, and Ha Tinh recorded 37.3 degrees.

Looking ahead, average temperatures across the country in August are expected to be 0.5-1 degree Celsius above the long-term average, with some regions potentially experiencing even higher temperatures. The south-central coast is likely to see more hot days than usual this month, with severe and locally extreme heat possible. In contrast, heat in northern Vietnam and from Thanh Hoa to Hue is expected to be less frequent than the long-term average.

In July, northern Vietnam experienced a widespread heatwave from July 12-14, with temperatures soaring to 36-38 degrees Celsius and exceeding 39 degrees in certain areas. The regions from Thanh Hoa to Hue and the south-central coast faced three heatwaves during July, with temperatures generally reaching 36-39 degrees Celsius and exceeding 40 degrees in some locations.
