Clothes guidance: Stick with shorts, T-shirts, tank tops and dresses as the heat can be really annoying for people from temperate or cold climates. Don’t forget to bring your swimsuit, sunscreen and sunglasses to enjoy fully Halong Bay’s summer.
Tips: From May to September, it is considered low season for tourism so most cruise agents and luxury hotels will have special summer promotion. But why is the low season while the climate is just perfect? Because it is the high season for local tourists so Halong City and some bay’s attractions near the mainland will be crowded, thus many expats want to avoid this period of the year. If you love the bustling scene then visit Halong Bay during this month to benefit good promotions or you can book a luxury overnight cruises, it will bring you to less crowded areas on the bay.
