Sapa Vietnam Weather And Climate

The climate of Sapa is unique to Vietnam. It is highly seasonal, with a subtropical climate in summer and a temperate climate during the winter. The hottest months are May and June when temperature may goes up to 29°C and the coldest months are December and January when temperature may drops down to 1°C.

In common with the rest of northern Vietnam, the wet season from May to September, with the heaviest rainfall occurring in July and August.

Humidity ranges from 75 to 91 percent with a yearly average of 86 percent. Climate varies considerably within the nature reserve. The prevalent wind direction for most of the year is west to east, leading to cloud formation on the upper slopes of the Fansipan massif. These high-altitude areas are covered by cloud most days of the year and have very high humidity. Cloud also penetrates into the valleys but these areas are usually less humid than the mountain slopes. In the extreme east of the district, around Ban Ho village, mean temperatures are considerably higher due to the lower altitude of these areas.
