Day temperatures may reach 35°C by mid-morning. Night temperatures are also higher and uncomfortable. The weather is extremely hot and humid because the humidity is extremely high at 85%, and the average remains between 75-85%.
The month of July is among the wettest months with frequent rainfall. Short-lived afternoon thunderstorms are the typical rain showers, which sometimes give an exhilarating respite from the heat. Sea temperature ranges approximately 29°C (84°F), which is ideal for swimming and other water activities. Typhoons and storms become more frequent this month and can be risky and "changeable" in the weather.
2. Pros and Cons
The flip side is that the sunny skies and hot temperatures are ideal for the fun in the sea activities such as swimming, kayaking, and snorkeling. Being in the off-season for overseas tourists, tourists can expect fewer people and a calmer atmosphere. Cruise ships tend to provide tempting discounts and offers during this time, making it favorable for economy-minded tourists.
Conversely, the higher storm and typhoon risk at this time may result in cruise and tour cancellations and may interfere with travel plans. The heat and the humidity can also be too much for some visitors. Furthermore, July is also peak time for domestic tourists who fawn over sites like Titop Island and Sung Sot Cave, making them busier and accommodations pricier by the order of locals.
3. What to pack for a trip to Halong Bay in July?
When you're packing for the trip, you should pack lightweight and breathable clothing to keep you comfy in the heat. Sunscreen with high SPF, hats, caps, and shades must be carried. Bring an umbrella, raincoat, or rainproof poncho during the sudden bouts of rain. Don't forget the swimsuit for enjoying the warm ocean waves and carry comfy walking shoes with you that can be used during hikes and shore outings. Keeping you well-hydrated is equally important, so it is highly suggested that you carry a refillable bottle for drinking water.
4. Tips & Planning Guide
July travelers to Ha Long Bay must be aware of several tips. Following the weather forecasts is vital because the cruise schedule may be impacted by sudden storms. Making bookings for rooms and trips in advance is also necessary because the trips are in great demand among home tourists. Make visits to the major sites during off-peak hours in order to avoid the crowds and utilize the better parts of the day that are cooler. Utilize the available offers on the cruises, and it may be worth considering going with the 3-day-2-night cruise because it provides a more free-and-easy schedule with time to accommodate whatever bad weather may arise.
If you are okay with heat and do not mind rolling with potential weather fluctuations, then July is okay to go see Halong Bay. Keep flexible for afternoon thunderstorms and sporadic typhoons, and be ready for more locals during the weekend trips, and you will still get one of the classic, gorgeous Halong Bay days.
