Northern Vietnam and several other regions are facing high temperatures alongside severe weather threats, including potential tornadoes, lightning strikes, and strong wind gusts during late-afternoon and evening storms on September 28. According to the National Center for Hydro-Meteorological Forecasting, daytime conditions remain predominantly sunny across multiple zones before atmospheric instability triggers widespread convective activity.
Northwestern and Northeastern Regional Temperature Spikes
In northwestern Vietnam, daytime temperatures reach highs between 32°C and 35°C, with specific pockets exceeding 35°C under sunny skies. Minimum temperatures range from 24°C to 27°C, though certain cooler mountain zones drop below 23°C. Late afternoon and evening hours bring scattered showers and thunderstorms carrying risks of tornadoes, lightning, and powerful wind gusts.
Similarly, the northeastern region experiences daytime highs of 32°C to 35°C or higher alongside sunshine. Winds blow from the south-southeast at speeds of 2 to 3 knots.
Capital City Forecast and Central Vietnam Conditions
Hanoi observes sunny daytime conditions with localized high temperatures reaching 33°C to 35°C or more. Southerly to south-easterly winds move at 2 to 3 knots. Nighttime brings expected showers and thunderstorms accompanied by lightning, tornadoes, and severe wind gusts, with low temperatures measuring 26°C to 28°C.
Provinces stretching from Thanh Hoa to Hue share this hot, sunny pattern, with maximum readings peaking between 32°C and 35°C and exceeding 35°C in select locations.
Southern Central Coast and Central Highlands Weather
The south-central coastal region reports sunny days paired with evening and nighttime scattered showers and thunderstorms. Lows stay between 24°C and 27°C, while daytime highs reach 31°C to 34°C.
Further inland across the Central Highlands, daytime highs range from 29°C to 32°C, and nighttime lows drop to 20°C to 23°C. Scattered thunderstorms develop in the late afternoon, posing standard hazards of lightning, strong gusts, and tornadoes.
Southern Vietnam and Maritime Warnings
Southern Vietnam registers daily highs of 31°C to 34°C and lows of 24°C to 27°C. Afternoon and evening hours generate scattered showers and thunderstorms accompanied by lightning, tornadoes, and gusty winds.
At sea, the National Center for Hydro-Meteorological Forecasting warns that the Gulf of Thailand and the southern portion of the South China Sea—including the southern area of the Truong Sa Special Administrative Region—face active storms. Marine forecasts indicate high probabilities of tornadoes, level 7-8 wind gusts, and wave heights exceeding 2 meters, endangering all vessels operating within those zones.
