Ha Long Bay’s weather splits into four seasons. Each has its perks and quirks. Here’s the rundown.
Spring (March-May)
Temperatures hover between 20-25°C. The air’s mild, and the bay blooms with soft greens. Rain’s rare, skies stay clear, and crowds thin out. It’s a solid pick for the best time to visit Ha Long Bay if you like peace. Kayaking feels effortless with calm waters. Photographers get crisp shots of karsts against blue skies.
Downside? It’s not peak beach weather—too cool for some. Still, spring keeps things simple and relaxed.
Summer (June-August)
Heat cranks up to 25-32°C. Humidity hits hard, and rain pops in, especially in July. The bay turns lush, almost glowing green. Summer’s the rainy season in Vietnam, but showers often pass fast. Budget travelers score here—fewer tourists mean lower prices on cruises.
The catch? Storms can disrupt plans. Pack rain gear and expect sweaty days. For sun-seekers, it’s a trade-off worth taking.
Autumn (September-November)
This is the gold standard. Temps drop to 20-28°C, skies clear up, and the breeze kicks in. The best time to visit Ha Long Bay shines here—calm seas, no fog, and perfect light. Crowds grow but don’t overwhelm. Kayaking, hiking, and cruising hit their stride.
No real cons. Autumn balances weather and vibe. Most travelers peg it as the top season for a reason.
Winter (December-February)
It gets chilly—15-20°C. Mist rolls over the water, wrapping karsts in a dreamy haze. Crowds vanish, and prices dip. Winter’s quiet suits introspective types. Think hot tea on a boat deck, watching the fog dance.
Flip side? Swimming’s out—too cold. Visibility drops with the mist. It’s not for everyone, but it’s got charm.
The best time to visit Ha Long Bay depends on your style. Weather shapes the experience—pick what fits. Want more on Vietnam’s seasons? See Vietnam Travel Seasons here.

Top Things must Do in Ha Long Bay
Ha Long Bay packs a punch with activities. Here’s what stands out.
Cruise the Bay
A boat trip’s the heart of it. Junk boats—those wooden beauties with red sails—glide past karsts. Overnight cruises let you sleep under stars, waking to misty mornings. Day trips work too, hitting key spots in 4-6 hours. The best time for cruising? Autumn’s smooth sailing beats summer’s choppy waves.
Book early—reputable operators fill fast. Look for meals onboard—fresh seafood’s a perk.
Kayak Through Hidden Lagoons
Paddle into the bay’s secrets. Luon Cave’s a gem—a tunnel opens to a lagoon ringed by cliffs. Waters stay calm, especially in spring or autumn. Kayaks rent cheap from cruise stops or villages. Wear a life jacket—safety first.
Autumn’s the best time to visit Ha Long Bay for kayaking. Clear skies and cool air keep it comfy.
Visit Floating Villages
Cua Van’s the big name. Homes bob on the water, tied to a fishing life. Locals row up, offering snacks or trinkets. It’s a glimpse of tradition amid the karsts. Tours often include a stop—ask for a guide who speaks English.
Winter’s mist adds a moody backdrop. Summer’s bustle shows daily life in full swing.
Hike Titop Island
A short climb, big reward. Titop’s 400 steps lead to a viewpoint—karsts stretch to the horizon. The beach below tempts swimmers in summer. Pack sneakers—the path’s steep but doable.
Spring or autumn keeps the hike pleasant. Views pop against clear skies—prime photo ops.
Explore Sung Sot Cave
Sung Sot means “Surprise Cave.” It’s huge—stalactites twist into wild shapes. Guides point out formations resembling animals or faces. Lights glow soft, keeping it eerie yet inviting. Tours hit it often—it’s a must-see.
Any season works. The cave’s cool year-round—a break from summer heat.
Beach Time at Bai Chay
Bai Chay’s the main stretch. Sand’s decent, water’s warm in summer. Vendors sell coconut water and grilled corn. It’s less wild than the bay’s core but good for a lazy day.
Summer’s the pick here—swim and sunbathe. Autumn’s cooler but still nice.

beautiful and natural scenery. The feeling of being immersed in nature is extremely comfortable.
I will come back ……..
We do not recommend an overnight trip. They’re overpriced, drinks, say, three times as much as on land. What there is to see can also be experienced with a day trip. We drove an hour to the well-known “surprise cave”, there drive felt ALL large and small boats. Therefore, there are the masses. After that, the ship did not move a millimeter. The next morning we visited an island with a viewpoint by tender boat. Again, the same here. Crowds wherever the eye looks. After that, it went back in no time. No recommendation.
We go here with one day tour and the view was amazing, its worth it, you must go to halong bay minimum once in your life time if you go to Vietnam.
On a luxury cruise, you could see beautiful limestone cliffs and the blue sea. In particular, the minister of sunrise and sunset remained an unforgettable memory. On the cruise we had a leisurely time enjoying fresh seafood dishes and comfortable service. This family-friendly trip was a special experience to feel the charm of Harong Bay.
Our time in Bai-to-Long Bay was truly special! The locals were very friendly and warmly welcomed. We enjoyed the unspoilt beauty of nature in a quiet and relaxing atmosphere. Surrounded by a blue sea and spectacular rocky mountains, it was like being in a dream. It’s a great spot for couples. I’d love to visit again!
