July marks the start of rain season in Halong Bay with a spike in rainfall to 474mm, during 15 wet days in the month. The maximum, minimum and average temperature remains roughly the same as June at 32oC, 26oC, 29oC respectively. 7 hours of blazing sun is expected during the 13 hours of daylight everyday. You will feel extremely sweaty and uncomfortable in this high temperature and humidity level. Bringing an umbrella or a fodable poncho and applying plenty of sunscreen help to shield yourself from both heavy rain and getting sunburn.
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. This period is the high season for local tourists so Halong City and some bay’s attractions near the mainland will be crowded, thus many expats 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.
