What You Need to Know Before Visiting Hanoi in December

The Hanoi weather in December is around 15°C, though it can sometimes go below 10°C. It may sound normal if you are from countries that are used to a sub-zero winter. But bear in mind that it is a different type of cold. It’s damp, it’s humid, and it seeps into your bones.

Not to mention, most buildings in Hanoi don’t have central heating and are poorly insulated, so the cold sort of follows you everywhere around.
