Christmas Winds: Why Winter Cancels Caribbean Tender Days
January is the month people book for the weather, and the month the weather answers back. The trades stiffen, north swell arrives, and tender ports start closing.
Nobody sells a Caribbean winter cruise on that fact, so here it is.
My quick take
The first time I lost a Grand Cayman call in January, I stood on deck looking at water that seemed perfectly fine. It was fine at deck 12, and it was moving several feet at the tender platform.
What I would do is treat December through February in the Caribbean as tender season with an asterisk. The ships still sail, the weather ashore is lovely, and the small boats are the part that quietly fails.
The thing I would not do is book a nonrefundable independent tour in a winter tender port. That is the one loss in this whole story that lands entirely on you.
The quick facts
- What the Christmas winds are: the seasonal stiffening of the northeast trade winds from roughly late November into February, driven by a strong and well-placed Atlantic high. The name is local, old, and used all over the eastern Caribbean.
- There is a documented winter peak: research published by NOAA’s Atlantic Oceanographic and Meteorological Laboratory describes a February peak in the Caribbean low-level jet, second only to the July maximum. The core sits over the central Caribbean between about 12 and 16 degrees north and 71 to 76 degrees west.
- How strong the jet core runs: the same work gives average jet winds of about 32 miles per hour (14.4 meters per second) in February, against an annual low near 19 miles per hour (8.5 meters per second) in October.
- The second problem is swell: North Atlantic winter storms send long-period northerly swell down into the Bahamas and the Greater Antilles. The National Weather Service defines swell as waves that have traveled out of the area where the wind made them, which is exactly why it can arrive on a windless morning.
- The threshold that matters ashore: the NWS Key West marine definitions put a Small Craft Advisory at winds of 20 to 33 knots, with 7 feet of seas as the local threshold. Tender operations often stop well below a gale, which starts at 34 knots.
- Where the bridge reads it: the National Hurricane Center issues the Caribbean offshore waters forecast in knots and feet, zone by zone. It is free, it is plain text, and it is the same product the ship is looking at.
- What you are owed: the Princess passage contract reserves the right to deviate from the scheduled ports of call and to omit any port, and says the captain may take any action deemed necessary for safety in his or her sole discretion. Refunds are not promised for changes outside the line’s control.
What the Christmas winds actually are
The trade winds are always there. What changes in winter is the pressure gradient driving them, because the Atlantic subtropical high strengthens and settles into a position that squeezes the isobars across the Caribbean basin.
Squeeze the isobars and you get sustained wind rather than gusts. A Christmas wind episode is typically several consecutive days of 20 to 25 knots from the east or east northeast, with higher gusts and a sea that keeps building because the fetch is a thousand miles of open water.
This is not a storm and there is no watch or warning for it. It is a climate feature with a name, much like the two monsoons that shape an Asia cruise, which is why sailors in Antigua and Saint Thomas have been calling it the Christmas winds for generations.
Why a north swell closes an anchorage that looks calm
The trades are only half the winter story. The other half is generated two thousand miles away, by the same North Atlantic depressions that dump snow on New England.
Those storms push enormous seas into the open Atlantic, and the long-period component of that sea keeps traveling long after the storm has gone. It runs south through the Bahamas, past Bermuda’s longitude, and reaches the Greater Antilles as a slow northerly swell.
Here is the cruel part. An anchorage on the west or north side of an island is sheltered from the easterly trades and completely open to that swell, so the days when the local wind drops are sometimes the worst days for tendering.
A north swell rarely looks dramatic from an upper deck. It shows up as a long, lazy heave that lifts a tender several feet against a fixed platform every 12 or 14 seconds, which is exactly the motion a crew will not board elderly passengers into.
The ports that feel it first
Grand Cayman is the headline case because it has no cruise berth at all. Ships anchor off George Town on the exposed west side of the island and run tenders in, which works beautifully until a northwest swell arrives.
The island has a fallback and it is worth knowing about. The Port Authority of the Cayman Islands lists an alternate cruise facility at Spotts Bay on Shamrock Road, on the sheltered south coast, which ships use when George Town is unworkable.
Belize City fails for a different reason. The anchorage sits several miles offshore behind the reef, the tender ride is long, and a stiff trade wind turns that crossing into a wet, bouncing 45 minutes before the swell is even a factor.
The Bahamian private islands are the ones people are most surprised by. Half Moon Cay and Princess Cays are both tendered, both face the wrong way for a winter north swell, and both cancel more often in January than in any summer month.
Cabo San Lucas belongs in this conversation even though it is not in the Caribbean. Its winter problem is northwest swell out of the North Pacific rather than the Atlantic, and the effect on a tender platform in the bay is identical.
Docked ports mostly shrug all of this off. Cozumel, Costa Maya, Grand Turk, Falmouth and Nassau keep running in the wind and swell that close an anchorage, which is why itinerary shape matters more than destination in winter.
What the ship does instead
The default answer is a sea day, and it arrives faster than you expect. A tender call that is scrubbed at 7 a.m. becomes an extra day at sea by 8, with the spa selling discounted treatments by 9.
The better outcome is a substitute port, and it depends entirely on whether a berth is free. Winter is peak season in the Caribbean, so the docked ports within reach are usually full, and the substitution often only works because another ship has also changed plans.
A third option is the alternate landing on the same island, which is what Spotts exists for. You still get ashore, you just get ashore somewhere with fewer taxis and a longer drive to whatever you booked.
What a ship almost never does is wait. Fuel, the next arrival slot and a fixed turnaround day at the other end of the week make a four hour delay more expensive than a missed call.
The things I would actually do
- Count your tender ports before booking: a January itinerary with three tendered calls is a different product from one with three docked calls. The brochure will not distinguish between them, and the deck plan will not either.
- Read the offshore waters forecast the night before: the National Hurricane Center publishes it by zone in knots and feet, and it costs nothing. Sustained winds in the 20s with seas above 7 feet in your zone is your warning shot, and my guide to reading a marine forecast before a cruise explains the rest.
- Watch the swell direction, not only the height: a 5 foot northerly swell can close George Town while a 7 foot easterly sea does not. Direction decides whether an anchorage is in the lee or in the firing line.
- Book the ship’s tour in tender ports in winter: it costs more and it is refunded automatically when the call is dropped. In December through February I think that premium is worth paying.
Fun fact: the Caribbean low-level jet is one of the few weather features where the sailors’ name and the research literature agree almost exactly. NOAA’s work puts the winter maximum in February over the central Caribbean, which is the same water that eastern Caribbean sailors have described as blowing hardest just after Christmas for generations.
How I would actually decide
If you are booking a Caribbean cruise for December, January or February, I would sort itineraries by how many calls are tendered rather than by which islands they name. Two tendered days in a seven day winter itinerary is a reasonable risk, and four is a gamble.
If a specific island is the reason for the trip, winter is the wrong season to trust a tender with it. That is the moment to fly, stay a week, and let the cruise be about something else.
A realistic word on accessibility
Winter conditions narrow the window for anyone who cannot manage a moving step. Ships will keep tendering in motion that they will not board a wheelchair or a walker into, so the call can technically go ahead while your day still ends at the shell door.
The structural answer is to choose winter itineraries built on berths. My guide to planning a port day for someone who cannot walk far goes through the ports where that is realistic, and in December through February the docked ones do a great deal of the work.
When to go, and the weather
The irony of Christmas winds season is that the weather ashore is close to perfect. Daytime highs across the islands sit in the low 80s Fahrenheit with low humidity, and the trade wind that is closing your anchorage is also what makes a beach day comfortable.
Late November through mid December is the softer end of the window. The high has not fully settled, the north Atlantic storm track is still finding its groove, and cancellation odds are noticeably lower than they are six weeks later.
Late January and February are the crunch. That is when the February jet peak and the busiest north Atlantic storm season overlap, and it is the stretch where I would build the most flexible itinerary I could.
Quick answers
What are the Christmas winds?
They are the seasonal strengthening of the northeast trade winds across the Caribbean from roughly late November into February. The name is local and long-standing, and the pattern matches a documented winter peak in the Caribbean low-level jet.
Do Caribbean cruises really miss more ports in January?
Tendered calls do, yes, and that is where almost all of the risk sits. Docked ports keep operating in conditions that shut an open anchorage down entirely.
Which Caribbean ports cancel most in winter?
The tendered ones on exposed coasts, with Grand Cayman, Belize City, Half Moon Cay and Princess Cays leading the list. Cabo San Lucas has the same problem on the Pacific side for the same reason.
Why cancel when the sea looks flat?
Because a long-period north swell can arrive with no local wind behind it at all. It lifts the tender platform every 12 or 14 seconds while the surface still looks calm from an upper deck.
Will I be refunded if a winter port is missed?
Ship excursions are refunded and port taxes are often credited back, but the passage contract does not promise more than that. Independent tours booked ashore are your own risk.
The last word
Winter in the Caribbean is not bad weather, it is beautiful weather with a small boat problem. Understanding that distinction is most of what separates a shrug from a ruined day.
If you want the mechanics of the cancellation itself, I have written about what happens when rough seas delay or cancel tendering, which covers the sequence from the bridge outward. For the specific ports, my guides to a tender day in George Town and to Cabo San Lucas both explain what the anchorage is like on a good day.
The private islands are the ones I would look hardest at, because they are sold as the guaranteed easy day and they are anything but in January. My guide to Half Moon Cay is worth reading with a winter sailing in front of you, ideally before you pay for a cabana.
How this guide was researched: Unless a first-hand visit is explicitly identified above, this guide is based on independent research using official meteorological, port and cruise line sources where available. The winter wind pattern was checked against published research from NOAA’s Atlantic Oceanographic and Meteorological Laboratory, marine advisory thresholds and swell definitions against the National Weather Service, and forecast products against the National Hurricane Center. Anchorage arrangements were checked against the Port Authority of the Cayman Islands, and itinerary policy against the published passage contract of Princess Cruises. Logistics and time-sensitive details were reviewed in August 2026. See our Editorial Policy.
