Northern Vietnam is experiencing its coldest days of the current cold spell, with temperatures dropping to between 16°C and 18°C, and even below 15°C in mountainous areas, according to the National Center for Hydro-Meteorological Forecasting (NCHMF).
The cold air mass strengthened early Sunday (Nov 3), affecting the northeastern region, parts of the northwestern highlands, and north-central provinces. Strong northeasterly winds of 39–61 km/h (levels 6–7, gusting to level 8) were recorded at Bach Long Vi Island.
Throughout today, the cold front will continue spreading across the northwestern region and the north-central coast, before extending further south to parts of the central region. On land, northeasterly winds are expected at levels 2–3 inland and 3–4 along coastal areas.
Due to the intensified cold air, northeastern provinces are forecast to see overcast skies and light rain. Daytime temperatures will range from 19°C to 22°C, while nighttime lows fall to 16–19°C, and below 15°C in highland areas. Northwestern localities will also see cloudy skies and scattered showers, with lows of 16–19°C and highs of 19–22°C. Lai Chau and Dien Bien may reach 25°C during the day.
In Hanoi, cloudy and drizzly weather is expected on Sunday and Monday (Nov 3–4). The capital will remain chilly, with temperatures ranging from 17°C to 21°C on Sunday and 17°C to 20°C on Monday. Rain is forecast to cease from Tuesday (Nov 5), when temperatures will rise slightly to 18–24°C, and continue warming gradually afterward.
Cold weather will also affect the north-central provinces of Thanh Hoa and Nghe An through Nov 5, bringing light rain and lows of 19–20°C. From Nov 6 onward, conditions are expected to turn drier and warmer.
According to the NCHMF, cold air activity across northern Vietnam is expected to increase in both frequency and intensity throughout November, resulting in more chilly days across the region.
