If you are comparing a BVI yacht charter for late fall, spring, or the holiday period, one question matters more than many guests realize: exactly when do summer rates end and winter rates begin?

The short answer is that the most common working pattern appears to be winter rates from December 15 to April 30 and summer rates from May 1 to December 14. But that is not universal. In our April 23, 2026 review of 722 named BVI yacht listings and supporting public rate pages, we found a smaller group of yachts publishing earlier winter start dates, including November 1 and even October 1.

That distinction matters because two charters in the same month can price differently depending on the yacht. It is also why experienced brokers double check the rate calendar when a booking falls around late October, November, early December, late April, or early May.

The standard BVI rate pattern we kept seeing

Across the public sources we checked, the most common season split was:

  • Winter: December 15 to April 30
  • Summer: May 1 to December 14

In our review, 231 yachts showed that standard Caribbean season wording on a checked public source. That makes it the clearest working default when a yacht does not publish a different cutoff date.

But we would still avoid treating it as a hard rule for every yacht in the BVI. A smaller set of yachts clearly publish different timing, and another large group simply does not publish enough detail to treat the cutoff dates as confirmed.

The yachts that clearly break the usual pattern

We found 13 yachts with a published yacht-specific season note that starts winter pricing earlier than the standard December 15 pattern. These are the kinds of yachts that can catch clients off guard if they assume the usual Caribbean calendar applies automatically.

The clearest examples include REVERIE and NAE KAE, both of which publish winter starting on November 1, and ANGELEYES, which publishes winter starting on October 1.

That is exactly why a broker should not rely on the default blindly when a client is traveling in shoulder season.

The full list of published exceptions we found

  • ALIZÉ: winter rates start November 1
  • ANGELEYES: winter rates start October 1
  • BAREFEET RETREAT: winter rates start effective November 1
  • Bavarian Bliss: new winter season rates begin on November 1 each year
  • Destiny Unbound: new winter season rates begin on November 1 each year
  • DO MORE: winter rates start effective November 1
  • Hazel Della: new winter season rates begin on November 1 each year
  • HIGH 5: new winter season rates begin on November 1 each year
  • Moon Shadow: new winter season rates begin on November 1 each year
  • NAE KAE: winter rates start November 1
  • Perfect Moon: new winter season rates begin on November 1 each year
  • REVERIE: winter rates start November 1
  • Southern Queen: new winter season rates begin on November 1 each year

What about the rest of the fleet?

The biggest group was not actually the published exceptions. The biggest open question was the yachts that do not publish a clear yacht-specific season note at all.

In our review:

  • 231 yachts showed the standard Caribbean default
  • 13 yachts showed a yacht-specific earlier winter start date
  • 478 yachts did not publish enough detail for us to treat the cutoff dates as confirmed

That means the standard December 15 / May 1 split is useful as a working rule, but it is still not the same thing as a confirmed yacht-level date unless the listing actually says so.

Holiday weeks are their own issue

Even when a yacht follows the usual summer and winter season pattern, Christmas, New Year, and sometimes Thanksgiving can still have separate pricing and separate rules. That is why holiday charters should always be checked individually, even if the general season dates look straightforward.

The practical takeaway for BVI charter guests

If your trip falls well inside winter or summer, the seasonal calendar is usually not controversial. But if you are looking at late October, November, early December, late April, or early May, the safest move is to check the exact yacht instead of assuming the standard Caribbean split applies automatically.

That is especially true if you are comparing several catamarans or motor yachts side by side. Two yachts can look similar on weekly rate alone, but a different seasonal cutoff can change which one is actually better value for your dates.

If you are narrowing down options, our brokers can help confirm whether a yacht is using the standard BVI rate calendar or a yacht-specific exception before you book.
