Director of the Centre for Hydro-meteorological Forecast Luu Minh Hai said the temperature not only plummeted in Sa Pa but also in some areas in the northern mountainous region.
The temperature was measured at 17.2 degrees Celsius on Pha Din Pass (Son La province), 16.5 degrees Celsius in Sin Ho (Lai Chau province), and 17.2 degrees Celsius in Mau Son (Lang Son province) on July 6.
The phenomenon occurred because the north had just welcomed a strong cold spell, accompanied with intense rain, Hai explained.
