The National Center for Hydro-Meteorological Forecasting has announced significant changes to the weather across Vietnam on January 5, 2025, primarily due to the incoming cold air mass. This weather shift will influence temperatures and precipitate varied forecasts throughout the northern, central, and southern regions of the country.
Starting with the north, it can be expected to experience noticeable cold weather, particularly during the early morning hours. Specific forecasts state, "Hanoi: Trời có mây, đêm không mưa, sáng sớm có sương mù và sương mù nhẹ rải rác, ngày nắng," indicating limited rainfall overnight, with scattered fog expected early, and sunny conditions developing throughout the day.
The temperature range for Hanoi will hover between 13 to 15 degrees Celsius at night, rising to between 23 and 25 degrees during the day. Moving west, the Northwestern region will see similar weather patterns, with forecasts projecting nighttime lows of 11 to 14 degrees, some areas dipping below 11 degrees, and daytime highs reaching between 22 and 25 degrees. Meanwhile, the Northeastern region will maintain comparable temperatures but may experience some areas with lows dropping to 10 degrees.
Further south, from Thanh Hóa to Thừa Thiên Huế, conditions continue with overcast skies at night but will brighten with sunshine during the day. Here the northern areas expect temperatures from 12 to 15 degrees at night and highs of 22 to 25 degrees, whereas the south could see minor rainfall with lows between 15 to 18 degrees and the same daytime highs.
Traveling to Đà Nẵng to Bình Thuận, it is noteworthy to mention predictions of potential thunderstorms. The northern part will likely experience scattered rainfall during the day, with temperatures ranging from lows of 19 to 22 degrees and highs from 23 to 26 degrees. The southern part will be warmer, with temperatures reaching up to 31 degrees with some areas expected to exceed this high, but may also see occasional rainfall.
The Tây Nguyên region will enjoy daytime sun but can expect evening rain and storm activity, with temperatures ranging from 14 to 17 degrees at night and highs reaching 24 to 27 degrees. Similarly, the southern-most regions will experience pleasant sunny daytime weather with scattered evening thunderstorms as well, and with the temperatures anticipated to range from the low twenties at night to as high as 32 degrees during the day.
For those near the coast, particularly the area from Bà Rịa - Vũng Tàu to Cà Mau, caution is advised. The weather service has identified risks from severe winds and waves. According to their report, "Chúng tôi cảnh báo, ngày và đêm 6.1, Vùng biển phía Tây khu vực Nam Biển Đông có gió Đông Bắc đến Bắc mạnh cấp 6, có lúc cấp 7, giật cấp 8-9," warning of expected strong gusts and turbulent seas. Waves could reach heights of 3 to 5 meters, posing dangers to maritime activities and coastal tourism.
Concluding the day’s forecasts, it is imperative for residents across all regions to stay informed about the weather reports, as fluctuated humidity levels, hitting around 75% across parts of the country, could exacerbate discomforts. People are advised to take precautions against sun exposure as the ultraviolet (UV) index is predicted to soar during midday hours. It is advised to use sun protection measures, including wearing wide-brimmed hats, applying effective sunscreen, and wearing UV-blocking clothing when venturing outdoors.
Weather conditions on January 5 across Vietnam will require attention and adaptability as communities brace for noticeable cold air mass effects and coastal monsoon shifts. Stay alert, keep safe, and enjoy the sun when it's bright!
