Caribbean Cruise Guide: When to Sail, Where to Go, What It Costs

Overview

The Caribbean is where cruising happens. Roughly a third of all cruise capacity worldwide is deployed here, which means more ships, more choice and lower fares than any other region. It also means the difference between a good Caribbean cruise and a mediocre one is entirely in the details: which route, which month and which ports you actually get off the ship for.

The single most useful thing to understand is that Eastern, Western and Southern Caribbean itineraries are genuinely different holidays, not marketing labels. Eastern routes are short-hop beach itineraries. Western routes reach Mexico, Belize and the Cayman Islands and are the ones with ruins and reef diving. Southern routes sail from Puerto Rico or Barbados, reach islands like Aruba, Bonaire and St Lucia, and have the best weather and the longest flights to get there.

This guide is built from our reviewers' 60-plus Caribbean sailings and a weekly fare sample across 40 departures. Where we give a price, it is what was actually being charged in 2026, not a brochure rate.

The Caribbean sits between roughly 10 and 25 degrees north, which is why the water stays between 79 and 84 Fahrenheit all year and why a February cruise and an August cruise visit the same beaches in very different conditions. The variable is not temperature, it is humidity and rain.

December through April is dry season. Humidity drops, trade winds pick up, and rain comes in short afternoon showers rather than day-long systems. This is also when North Americans want to escape winter, so it is the most expensive window by a wide margin.

June through November is hurricane season. In practice, the risk is heavily concentrated: August, September and early October account for the large majority of named storms affecting cruise itineraries. June, July and late November are usually fine and materially cheaper.

Cruise lines handle storms by changing the itinerary, not by cancelling. A ship will simply sail west instead of east and call at different ports. That is safe and it is also the main reason to buy travel insurance that covers itinerary change rather than only cancellation.

• Water temperature stays between 79 and 84 Fahrenheit all year.
• Dry season December to April; wet and humid June to November.
• Hurricane risk concentrates in August, September and early October.
• Ships reroute around storms rather than cancelling, so ports can change at short notice.

The best time to go

There is no single best month, only trade-offs between price, weather and crowds. Late April and early May is the window we recommend most often: dry-season weather, post-Easter pricing and water still warm from winter.

If you have school-age children, you are choosing between late June, which is hot and humid but usually storm-free, and the Christmas and Easter peaks, which carry a 40 to 70 percent fare premium.

The ports, honestly assessed

Caribbean ports vary enormously in whether they justify an excursion. Some are genuinely worth a full day and a guide; others are a shopping arcade attached to a pier where the best use of your time is to stay on the ship and enjoy an empty pool deck.

The list below flags which is which. As a rule, if you can walk to a good beach from the pier, do that and save the excursion money for the ports where you cannot.

• CozumelMexico

  The best diving and snorkelling in the Western Caribbean. Take a boat to Palancar reef rather than the shore snorkel by the pier.

• Grand CaymanCayman Islands

  Seven Mile Beach is a $20 taxi from the tender pier and is genuinely world class. Stingray City is heavily oversold.

• St ThomasUS Virgin Islands

  Magens Bay is the reason to come ashore. The duty-free shopping is the reason most passengers never see it.

• St MaartenSint Maarten

  Maho Beach for the aircraft landings, Orient Bay for the actual beach. Water taxi into Philipsburg is $8 return.

• NassauBahamas

  The weakest major Caribbean port. Walk to Junkanoo Beach or stay aboard; the downtown area is congested and unremarkable.

• RoatanHonduras

  West Bay Beach has the best reef access from any Western Caribbean port. Book a private taxi rather than a ship excursion.

• ArubaAruba

  Outside the hurricane belt and reliably dry. Eagle Beach is a short bus ride and one of the best in the region.

• BarbadosBarbados

  A genuine island rather than a cruise stop. Rent a car and drive the east coast.

• St LuciaSaint Lucia

  The Pitons and the drive-in volcano justify a full-day excursion. One of the few ports where the ship tour is worth it.

• Belize CityBelize

  A tender port with a long transfer to anything worth seeing. Only book if you want the Mayan ruins at Altun Ha or Lamanai.

• Puerto RicoPuerto Rico

  Old San Juan is walkable from the pier and is the best free port experience in the Caribbean.

• CuracaoCuracao

  Willemstad's Handelskade waterfront is a UNESCO site and a five-minute walk from the ship.

Weather, month by month

Caribbean weather is more consistent than almost anywhere else on the cruise map. The numbers below are central-Caribbean averages; Southern Caribbean islands such as Aruba and Curacao run one to two degrees warmer and considerably drier.

Rain days are the number that matters, not rainfall totals. A September afternoon downpour lasting twenty minutes counts the same as a grey drizzly day in the totals, and they are not the same experience.

What it actually costs

The Caribbean is the cheapest cruise region in the world because supply is enormous. A seven-night balcony sailing in September can cost less than a week in a mid-range Florida hotel.

The line item people underestimate is not the fare, it is what happens ashore. Seven ports at $120 per person per excursion is $840, which is often more than the cabin cost.

Travel tips from our sailings

• 1

  Fly into your departure city the day before. A same-day flight that is delayed means missing the ship, and travel insurance will not make that less painful.

• 2

  In ports where you can walk or take a $10 taxi to a good beach, do that instead of booking a ship excursion. St Thomas, Grand Cayman and Aruba all qualify.

• 3

  Book ship excursions only where the transfer is long, the site is remote or missing the ship would be catastrophic. Belize and St Lucia are the clear cases.

• 4

  Southern Caribbean itineraries sit below the main hurricane belt, so book those if you must sail in September.

• 5

  Carry small US dollar bills. Most Caribbean ports take dollars, and nobody has change for a fifty.

• 6

  Check whether your itinerary includes a private island. They are genuinely good and they replace a weak port day such as Nassau.

• 7

  Sea days in January and February can be rough on Eastern routes because of Atlantic swell. Book midship if you are prone to seasickness.

Caribbean packing essentials

• Reef-safe sunscreen, since Mexico and several islands ban oxybenzone-based products and confiscate them at reef sites.
• Water shoes for Roatan, Bonaire and any rocky-entry snorkel site.
• A light rain shell rather than an umbrella; Caribbean rain is brief but heavy.
• One long-sleeved UPF shirt, which beats reapplying sunscreen every ninety minutes.
• A refillable water bottle, because ships charge for bottled water and most ports do not sell it cheaply.
• A dry bag if you plan any boat-based excursion; tender rides get you wet more often than you expect.
