When to visit
Weather in Halong Bay
If you’re coming to Halong Bay, try to visit from April to June or September to November. You’ll have a better chance of enjoying sunny skies and pleasant temperatures. Other times of year, downpour or heavy mist is common, and tropical storms can sometimes cause cruise cancellations. However, if you’re on the water during this time you can experience a more mystical side of Halong Bay, with its famous karsts shrouded in mist. Temperatures in January can be frigid, so be sure to bring warm layers.
Weather in Hanoi
The best time to visit Hanoi is usually from April to June or from September to December. From April the days are normally hot, occasionally above 30 degrees with clear skies. September to November sees cooler temperatures of around 25 degrees and sunny skies -- perfect for exploring the capital.
If you’re coming to Hanoi in June, expect soaring temperatures with humidity highs of 40 degrees, and the rainy season is full swing (June to August). December is cool, misty and atmospheric, however from late December until March temperatures are surprisingly cold with lows of 10 degrees. You’ll want to bundle up.
Weather in Sapa
Vietnam’s Northern destinations such as Sapa have a much cooler climate than the rest of the country, particularly from late December until March. Sapa sees the occasional snowfall in January, so be prepared. Hotels in the area are equipped with heated blankets and local spas offer herbal baths for you to soak in and warm up. Sapa is near-perfect in late April, as flowers bloom and skies are clear. Early October is also lovely, as its impressive tiered rice paddies turn golden just before harvest.
Weather in Mai Chau
March to May and September to November are the best times to visit Mai Châu. October is perhaps the most ideal month because harvest takes place and the rice takes on a glorious golden hue.
