Vietnam is preparing for a chilly week as the National Center for Hydrometeorological Forecasting has announced the arrival of a new cold front starting February 12, 2025. This cold air mass will significantly affect the southern parts of Sơn La and Hòa Bình, as well as the Northeast region, bringing expected drops in temperature and increased chill, particularly for mountainous areas.
The forecast for February 12 indicates scattered light rain across several northern provinces, coupled with fog especially during the early morning and evening hours. The central areas, from Quảng Bình to Thừa Thiên Huế, may see occasional rain, and coastal regions are also expected to experience light showers and mist.
According to the meteorological center, the Northern region will start feeling the impact of this cold front from the night of February 12. Temperatures are predicted to plummet, with the lowest expected to range between 14°C to 17°C throughout much of Northern Vietnam, and even lower, between 11°C to 13°C, in mountainous areas. Some elevated regions might experience temperatures dipping below 10°C, increasing the likelihood of frost and severe cold conditions.
The backdrop to this cold weather phenomenon is rooted within the dynamics of air pressure changes which are coupled with western winds at high altitudes. Increased moisture from these interactions is projected to result in light rains, fog, and visibility issues, particularly during early mornings.
Specifically for Hanoi, residents can expect mostly cloudy skies with likelihoods of mist and light rain during the nighttime and early morning hours. Temperatures are forecasted to stay relatively low but should see slight warming during midday hours, with highs expected to reach around 20°C to 22°C during the day following the night’s chill.
Homes and public spaces will likely feel the effects of persistent fog and humidity during this time, reaching its peak beginning February 12 back through February 20. This extended period of high humidity can cause discomfort and health concerns, particularly for vulnerable populations like the elderly and young children.
People are advised to take precautions such as keeping their environments well ventilated to combat the dampness and to dress warmly to avoid cold-related illnesses. It is also suggested to limit outdoor activities during misty mornings to prevent exposure to the cold and slippery conditions.
On the other hand, weather conditions across southern Vietnam remain more stable. Areas such as Đà Nẵng to Khánh Hoà will see moderate to heavy rains due to the influence of the cold air coming from the north, pushing warm moisture to create more precipitation.
Throughout the week, temperatures for the Southern region will range from 22°C to 35°C, which is typical for this time of year, with high humidity levels and the potential for rainfall coming sporadically.
For the Central region, light showers are expected but won't be as persistent, with the maximum temperatures sitting around 24°C, contrasting sharply with the chill gripping the north. The highlands of Tây Nguyên may also experience scattered rains but with daytime temperatures reaching between 27°C and 30°C.
This contrasting weather will require citizens to adapt quickly. While Northern areas will need to brace themselves for what appears to be one of the coldest weeks yet, the south remains warmer and wetter, consistent with its tropical climate.
Residents should remain tuned to local alerts for updates as meteorologists continue to monitor these changes closely. Preparedness will be key, particularly for the colder regions where significant temperature differences can be challenging.
The early onset of this cold season is not uncommon; it serves as a reminder of how fickle Vietnam's weather patterns can be and how quickly conditions can turn. For those living within these affected areas, making small changes can lead to substantial benefits, keeping both health and comfort levels optimal.
