Ha Long Bay in October: an ordinary month, two traps

Yes, October is a sound month for a Ha Long cruise. On our reviews it sits close to the yearly average once a single bad day on a single boat is set aside. The two things that do go wrong in October are specific enough to check before you pay: the tail of the typhoon season, which in ten years of wind records falls mostly in the first three weeks, and a ticket that says Ha Long for a boat that sails Lan Ha.

The review figures below come from the 859 guest reviews posted in October, out of 10,058 dated reviews we hold for 74 boats, counted on 16 October 2026. The November guide covers the drier month that follows.

How does October compare with the rest of the year?

October scores a little worse than the average month, and most of the gap comes from one day. As posted, 5.6% of October reviews sit at one or two stars against 5.2% across all twelve months. On the three complete years from 2023 to 2025 the gap is wider, 7.0% against 5.9%, and only September is worse.

	October as posted	October without the 14 October 2025 cluster	Same, 2023 to 2025 only	All months, 2023 to 2025
Reviews	859	854	597	5,908
One or two stars	48 (5.6%)	43 (5.0%)	37 (6.2%)	351 (5.9%)
Average rating	4.67	4.69	4.63	4.65

Take those five reviews out and October sits within a few tenths of a point of the year on either count. Our month by month comparison sets all twelve side by side.

Two things pull the full count around. October 2026 is a short month in our set, ending on the 10th, and 141 of its 200 reviews sit on one boat’s listing whose reviews we hold almost entirely from September and October 2026, none of them below four stars; without that listing October runs at 6.7% across all years. And October 2025 holds 28 of the 48 low scores, at 7.8% against 5.5% for that year. In 2023 and 2024 October came in below its own year, at 7.2% against 8.8% and 5.2% against 5.8%.

What went wrong in October 2025?

Two things: one boat’s bad day, and four trips cut short or never started.

On 14 October 2025, five one-star reviews of one Lan Ha boat went up on the same day. The three with text all say the guests expected Ha Long Bay and were taken elsewhere; two of them name Lan Ha. Same-day bursts happen in other months too: the largest in our set is nine low scores for a different boat on 18 August 2025.

Four more low reviews describe a trip that was cut or never started, and all four mention a typhoon. A guest posting on 4 October had an overnight trip turned into a day cruise that ended at 5 pm because a typhoon was coming. Four days later a guest on a Ha Long boat wrote, in Chinese, that the boat waited at the harbour for permission because a typhoon was due, then fitted two days of stops into one. A three-day trip that began on 3 October lost its second night to what that guest calls Typhoon Paolo. The fourth is a traveller whose flight to Hanoi was cancelled ahead of what they call Typhoon Ragasa, which they date to 26 September 2025, and who writes that they were offered neither a refund nor a new date.

That last case is the one to plan around. What failed was the flight into Hanoi, and a clause about the bay closing would have done nothing for that traveller.

Do October guests write about different things?

Barely. On the 471 October reviews we have classified by subject, against 6,960 across the year, the mix is close to the annual one.

Subject mentioned	October	All year
The crew	79.6%	81.6%
The food	53.7%	52.5%
The cabin	32.5%	30.6%
Itinerary changed or cut	6.6%	4.3%
Booking or admin trouble	at least 5.9%	at least 3.7%

A mention is not a complaint, and our booking label misses some cases, so that row is a floor. Take out the 14 October cluster and the storm and closure reviews, and itinerary changes fall to 5.6% and booking trouble to 5.2%, both still a little above the year.

Is there still typhoon risk in October?

Yes, and not only at the start. Ten years of ERA5 reanalysis, a model grid about 25 km wide that smooths a storm’s peak below what a station would record, give October 36 days with gusts of 50 km/h or more: 13 in the first ten days, 14 in the middle ten and 9 after the 20th. The strongest was 10 October 2021, and our Ha Long Bay weather by month puts October’s rain and storm days beside the other eleven months. The reviews say less. Storm and typhoon words appear in 5 of the 776 October reviews with text, 0.6% against 0.3% across the year, two of them looking back at trips in late September. Rain comes up in three, two from October 2025, and neither of those trips was stopped by it.

The limitation is in the paperwork. Your operator does not close the bay. In the storms we checked, Quang Ninh’s Department of Agriculture and Environment asked the port authorities to stop licensing boats from a stated hour, and the stop ended only with the final bulletin on that storm. For Ragasa the stop ran from 10:00 on 24 September 2025, which Lao Động reported that morning. For storm no. 4 of 2026, sightseeing and overnight stays were to stop being licensed from 07:00 on 22 August (Nhân Dân, 22 August 2026). What a closure costs you is the seller’s rule. The seven cancellation ladders we have recorded set penalties by days before departure, and weather rules sit in separate clauses that sellers write differently. Paradise Vietnam’s weather page, read on 6 August 2026, says the port authority usually makes its call at 3 pm on the day you sail. That is one seller’s account; the Ragasa stop began at 10:00. Leave before that call and nothing is refunded. If you are already at the marina, a full cancellation costs $25 a head for the lunch served while you wait and the rest is refunded; a day-cruise-only permit costs $95 a head; and a two-night trip that loses its second day is billed as one night. Other sellers word it differently, so get your own seller’s rule in writing.

Whatever your October dates, ask by email what a closure on your date means, how much comes back if two nights become one, and whether any of it applies when the bay is open but your flight is cancelled. Our cancellation policy guide shows how far the ordinary ladders differ.

Is early October riskier than late October?

For storms, the reviews point early, while the gust record spreads the risk across the first three weeks. Low scores lean slightly late: 17 of 246 reviews posted from the 21st (6.9%), against 10 of 186 in the middle ten (5.4%) and 16 of 281 in the first ten days (5.7%), once the 14 October cluster and one listing whose reviews we hold almost entirely from September and October 2026 are set aside. The counts are too small to call a pattern. The two storm and closure reviews that give dates give 26 September and 3 October.

Trips come first, reviews later. One review posted on 24 October describes a trip on 5 to 7 August. We cannot resolve the month any finer than this.

Will it be crowded in October?

No more than usual. Crowd words show up in 2.3% of October text reviews against 2.9% across the year, and crowding as a subject in 5.9% of classified October reviews against 6.6%.

October guests who mention crowds name the big caves most often, though not only them. One Alisa Premier guest enjoyed Sung Sot less because of the crowds; another on the same boat found the first day’s caves hectic and, on the extra day of a two-night trip, a kayak trip to smaller caves much calmer. Others describe twenty kayaks sharing one small patch of water, and anchorages with twenty to thirty boats moored together.

Ha Long, Lan Ha or Bai Tu Long in October?

Choose the bay for the trip you want. October moves the numbers between them a little, on samples too small to choose by.

Bay	October reviews	One or two stars	All year
Ha Long	243	18 (7.4%)	5.5%
Lan Ha	563	27 (4.8%)	4.9%
Bai Tu Long	53	3 (5.7%)	6.0%

Lan Ha’s figure includes the 14 October cluster and that same listing; without both it is 22 of 417 (5.3%). Ha Long’s 7.4% rests on 243 reviews. We would not choose a bay on them.

The name on the ticket is the trap. Lan Ha trips are routinely called Ha Long: 85 of the 520 October reviews with text on Lan Ha boats call the trip Ha Long and never mention Lan Ha. Lan Ha days centre on swimming and kayaking, Ha Long days on caves, so ask which bay the boat anchors in overnight and which harbour it leaves from. Most Bai Tu Long boats leave from the international cruise port at Bai Chay, but Tuan Chau serves both Lan Ha and Ha Long, as our harbour guide explains. The three bays compared covers the rest.

Which boats did guests rate well in October?

Six boats came through October without a single one or two star review on 18 or more reviews. We have left out the listing whose reviews we hold almost entirely from September and October 2026, because one month’s reviews from it say little about a typical October. The last row is the next most-reviewed boat of the month, with three low scores, for contrast.

Boat	Bay	October reviews	October average	All-year average
Stellar of the Seas cruise	Lan Ha	37	4.95	4.99
Emeraude Classic	Ha Long	33	5.00	4.85
Renea	Bai Tu Long	25	4.88	4.78
Alisa Premier	Ha Long	19	4.95	4.88
Indochine	Lan Ha	20	5.00	4.75
Nostalgia	Lan Ha	18	5.00	4.84
Catherine	Ha Long	44	4.66	4.65

Twenty reviews in one month show a boat held up in October, and no more than that. Stellar of the Seas is the strongest case: 37 October reviews without a low score, and an all-year average built on 499. If it is Ha Long’s caves you want, Alisa Premier, Emeraude Classic and Catherine are the Ha Long boats here; Renea is the Bai Tu Long option, and the other three sail Lan Ha.

Questions people ask about October

What happens if the bay closes while I am booked? Your seller does not make that call. Quang Ninh’s Department of Agriculture and Environment asks the port authorities to stop licensing boats from a stated hour until the final bulletin on the storm. What you get back has no single rule. The penalty ladders we have recorded do not cover it, and the sellers who publish a weather rule do not agree: one bills a two-night trip that loses its second day as one night, another promises only a new arrangement or a refund under each cruise’s policy. Ask your seller by email, and ask separately about a cancelled flight, because that case sits outside a bay closure. The two closures of summer 2026 are covered in what changed on Ha Long Bay in 2026.

Is it warm enough to swim in October? Modelled sea-surface temperature for October averages 28.3°C over the three years we hold, and guests do swim. One review posted in late October 2025 describes an afternoon swim in water the guest found warm and clear; two others found the water near the anchorages dirty enough to put them off. On air temperature the reviews split: one late-October guest found it a little cold, another waited an hour for a cave in hot sun. Pack for both.

Should I book two nights in October? It depends which risk bothers you more. A second night can buy calmer excursions, as one Alisa Premier guest found, but it also gives a storm more of your trip to take: the October guest who lost a second night to a typhoon says about 20% of the total came back. For two nights at any point in October, get the cut-short refund in writing first.
