Weather & Climate In Vietnam

Different latitudes and widely varying physical relief lead to great climate changes from one place to another. In the dry season, between November and April, monsoon winds blow northeastwards across Chinese coastlines and over the Gulf of Tonkin, absorbing much humidity. Consequently, as compared to summer or rainy season in most of the country, winter is just a dry period.

On average for a year and considering the entire country’s terrain it can be said that temperature here is higher in the south than in the north; also it is higher on the plain than in mountainous parts. In Mekong Delta and southern plains around Ho Chi Minh City, temperatures do not change much throughout the year (ranging from 21°C to 28°C). The seasonal variations are more intense in mountains, plateaus and North where temperature ranges between 5° C (41.0° F) in December-January) and 37° C (98.6° F) in July-August. As opposed to mountains, plateaus and northern areas which experience such sorts of changes when their temperatures varies from as low as -5 degrees Celsius in December- January to as high as -87 degrees Celsius during July-August.
