Most tours still operate unless weather is severe

It depends on which excursion you're on. Usually, tours are only canceled if there’s a serious storm or high winds that make it unsafe

It depends on whether you're doing a Halong Bay tour or a Hanoi city tour.

For Halong Bay, tours are only canceled if the Port Authority issues a ban due to typhoons or storms. If there’s no ban, the boat sails even in the rain! You can still visit caves, but kayaking might be limited

For Hanoi tours, rain doesn't stop anything. Just grab an umbrella or a poncho for a unique experience! :D"
