According to the National Center for Hydro-Meteorological Forecasting, intermittent cold fronts will bring cool weather starting this week, with a stronger cold spell expected in early November, potentially marking the first significant drop in temperatures this winter.

For the next 1-2 days, scattered rain is expected in Northern Vietnam and North Central Coast regions, particularly in the northeast and northern delta areas.

Temperatures will dip overnight, bringing a chill to mountainous areas. Around November 5, a second, more intense cold front will lower temperatures across the entire northern region.

Forecasts indicate that La Nina, a climate pattern that typically brings wetter and cooler weather to Southeast Asia, is expected to persist from November 2024 to April 2025 with a probability of 60-70%.

This pattern is anticipated to bring longer, harsher cold spells to Northern Vietnam, especially in mountainous areas where frosty conditions and even snowfall are likely.

In early November, temperatures across Northern Vietnam will decline sharply, with areas like Lang Son dropping to around 19°C. Hanoi is forecasted to reach lows of 18-21°C around November 5, with daytime temperatures ranging from 20-24°C.

The effects of La Nina may lead to harsher winter conditions, especially from December 2024 to January 2025. In addition to cold spells, La Nina could increase typhoon activity in the East Sea, which may bring storms or tropical depressions to the Central and Southern regions of Vietnam through January.

These weather events could include storms, lightning, hail, and strong winds, with significant rainfall expected across Central and South-Central Vietnam.

Meteorologists project that La Nina will persist through early spring, potentially until April 2025. During this period, cooler weather may continue across Northern Vietnam, with the possibility of out-of-season rain events in the Mekong Delta and Southern regions during the dry season.
