IN A NUTSHELL
  • April signals the end of the peak season so it will be less busy than previous months.
  • Temperatures are higher but so is rainfall, but don’t expect it to rain every day.
  • Another great month to enjoy the waters of Halong Bay, bring your swimsuit and goggles.

April Weather in Halong Bay

April is much warmer than previous months so you can finally don your shorts and flip flops and really enjoy that sunshine and warm breeze. April is one of the months with the highest amount of daily sunshine and keeps to similar levels of humidity as those seen in March, at around 75%. This isn’t too bad compared to the rest of the summer which can see humidity levels rise to above 90%. Rainfall rises in April, especially towards the end of the month, but it isn’t enough to cause much disruption so don’t let that put you off!

What to Pack

With highs of 28°C in April, you should prepare to bring summer clothes; shorts, t-shirts, dresses, and skirts. The sun will be strong so bring a hat if you have one and, as always, where there is sun you should bring sunscreen! It is unlikely that there will be any cold days, but if you catch a chill easily you might want to bring a light sweater. 

Pro tips: Bring a swimsuit if you enjoy swimming or water activities.
