Frost has appeared for the second time this winter on Fansipan’s summit, with temperatures plummeting to -1°C on December 23. Thin layers of frost-covered trees, wooden walkways, and paths early in the morning, persisting for about four hours before melting under the sun.
This phenomenon, caused by moisture freezing into solid, salt-like formations, occurs when air temperatures drop below 4°C. Fansipan, at 3,143 meters above sea level, experienced its first sub-zero temperature of the season, following an earlier frost event on November 20 when temperatures reached 2°C.
With forecasts predicting continued low temperatures, more frosty mornings are expected. Sa Pa, a top destination in northern Vietnam, is leveraging its winter charm to attract visitors with seasonal events like the Fansipan Succulent Festival, the Vietnam Mountain Marathon, and the Cherry Blossom Festival at O Long tea hills.
