Halong Bay Storm Season: 28 Essential Tips for Your 2025-2026 Adventure
The majestic limestone karsts of Halong Bay rise dramatically from emerald waters, creating one of Vietnam’s most iconic landscapes. But when dark clouds gather and winds intensify during Halong Bay storm season, this UNESCO World Heritage Site transforms into a different kind of spectacle. For travelers planning a 2025 visit, understanding the bay’s seasonal temperament is crucial for a safe, memorable journey through this natural wonder.
Understanding Halong Bay’s Storm Season in 2025-2026
Halong Bay experiences a distinctive monsoon climate that divides the year into clearly defined seasons. The storm season typically runs from June through September, coinciding with Northern Vietnam’s summer monsoon pattern. During these months, the region becomes susceptible to tropical depressions, storms, and occasionally typhoons originating from the South China Sea.

Weather Patterns and Forecasts for 2025-2026
According to the latest climate projections from the Vietnam Meteorological Department, the 2025 storm season is expected to bring:
Month | Average Temperature | Rainfall | Humidity | Storm Probability
|
---|---|---|---|---|
June | 82-90°F (28-32°C) | 180-220mm | 80-85% | Moderate (30%) |
July | 84-93°F (29-34°C) | 250-300mm | 85-90% | High (45%) |
August | 83-91°F (28-33°C) | 300-350mm | 85-90% | Very High (60%) |
September | 80-88°F (27-31°C) | 200-250mm | 80-85% | Moderate (35%) |
“The 2025 forecasts indicate a slightly more active storm season compared to previous years, with potentially 2-3 major weather systems affecting the Halong Bay region directly,” notes meteorologist Nguyen Van Minh from the National Center for Hydro-Meteorological Forecasting.

Traveler Testimonials: Real Storm Season Experiences
Sarah Thompson, a Canadian photographer who visited in August 2024, shared: “We experienced a one-day delay due to an approaching storm. Our cruise provider immediately arranged accommodations in Hanoi and kept us updated hourly. When we finally sailed, the post-storm atmosphere created the most dramatic lighting conditions I’ve ever photographed—misty karsts emerging from calm waters with incredible cloud formations.“
James Wilson from Australia noted: “July 2024 brought occasional heavy downpours, but they typically lasted only 1-2 hours. Between rain showers, we enjoyed surprisingly clear visibility and fewer crowds. The cruise staff expertly adjusted our itinerary to ensure we experienced all activities, just in a different sequence.“
