What to Wear & What to Bring for a Sunset Cruise in St. Thomas
What to wear on a St. Thomas sunset cruise comes down to one simple rule: dress beach-casual and bring one layer for after dark. Every cruise in our lineup of sunset cruises already covers the open bar, the appetizers or dinner, and the champagne toast, so what's left on your packing list is genuinely short. Evenings here run warm, upper 70s to mid-80s Fahrenheit even in the cooler months, but the breeze off open water picks up once the sun drops, and that's the one detail first-time sailors forget to plan for.
Quick answer
Dress beach-casual for a St. Thomas sunset cruise: shorts, a sundress or a light top, plus one thin layer for after dark, when the breeze off open water turns cool even on an 84-degree night. Flat, non-slip sandals or bare feet work on deck, and the crew already has the drinks, food and champagne toast covered, so the list on you is short.
Key takeaways
- Tours cover the drinks, the food and the champagne toast, so your own list is short: clothes, one layer, shoes, sunscreen
- The one thing on you: a light layer for after dark, when the open-water breeze turns cool
- Don't wear: heels or an unsecured flip-flop, both fail on a moving deck
- Evening air runs upper 70s to mid-80s Fahrenheit year round, water stays 79 to 84°F
- The footwear answer in one line: flat, non-slip sandals or bare feet, never heels
- Packing barely changes by season here, the only shift is how soon you'll want that layer on
What to Wear on a Sunset Cruise in St. Thomas
Base Layer / Swimwear
Beach-casual is the rule across every cruise on this list: shorts and a t-shirt, a sundress, a linen shirt, whatever you'd wear to an early dinner on the water. None of the six cruises put you in the water yourself, except the full-day Turtles, Pizza Pi & Sunset Sail, which builds in an actual snorkel stop and calls for a swimsuit under your clothes. For the five evening-only sails, quick-dry synthetic fabric beats cotton for one simple reason: sea spray reaches the rail seats on an open-water catamaran, and a soaked cotton shirt stays cold and clammy for the rest of the ride.
Sun Protection
The last hour of daylight before boarding is still strong enough to burn, especially on an open deck with reflected light off the water. A light long-sleeve layer or a wide-brim hat handles the walk to the marina and the first thirty minutes on the water; after that, the sun sits low enough that sunscreen alone covers you. Reef-safe sunscreen is the considerate choice around any Caribbean reef, and several of the crews we sail with specifically ask guests to skip older sunscreen chemicals known to harm coral, so packing a reef-safe formula from home saves you a conversation at check-in.
Wetsuit / Outer Layer
None of these cruises call for a wetsuit. Water in St. Thomas holds at 79 to 84°F year round, warm enough that even the snorkel stop on the full-day sail runs comfortably in a swimsuit alone. What you actually want is closer to the opposite of a wetsuit: a thin cover-up, a light zip-up, or even just a long-sleeve shirt for after the sun goes down.
Once you're on open water past sunset, the breeze cuts through bare shoulders fast, even on an 84-degree night, and that single layer is the difference between shivering on the ride back and enjoying it.
Footwear
The rule for footwear here follows the deck, not the fashion. Flat, non-slip sandals are the safe default, and going barefoot once you're aboard is common and fine on a catamaran deck. Closed sneakers work for the walk from the parking area to the dock but come off quickly once you're seated, since most guests prefer bare feet or sandals for the actual sail.
What's genuinely not okay: heels, which sink into teak decking and turn an ankle on a moving boat, and any flip-flop or sandal without a back strap, which slides off the moment the boat rocks and is gone in the water for good.
A quick color guide for what actually works on deck:
| Color | Good? | Why |
|---|---|---|
| White | Good | Reflects the last hour of strong sun and stays visible to the crew at the rail after dark |
| Black | Situational | Hot in the pre-boarding sun, but a fine choice once the light fades and heat stops being a factor |
| Bright or neon | Good | Easy for the crew to spot you at the rail once the light drops, useful on the bigger catamarans |
| Pastels and light colors | Good | The classic sunset-cruise look, and cooler than dark fabric during the last hour of daylight |
| Cotton | Bad | Soaks up spray at the rail and stays damp and cold once the evening breeze picks up |
| Quick-dry synthetic | Good | Dries fast if spray or a splashed drink catches your shirt |
| Dark solids after dark | Good | Fine for the return leg once the sun is down and glare is no longer a factor |
What to Bring
Tours cover the drinks, the appetizers or dinner, and the champagne toast, which keeps this list short. Here's everything worth packing:
- Light layer or cover-up, since the breeze turns cool once the sun is down
- Reef-safe sunscreen, reapplied before boarding rather than mid-cruise
- Cash for the crew, since gratuities aren't included on any cruise
- Phone or camera in a dry pouch, since spray reaches the rail seats
- Motion-sickness tablet, taken an hour before boarding if you're prone to it
- Sunglasses, since the last hour of daylight sits low and bright
- A hat you don't mind losing, the wind off open water is real
- Dry shoes for after: flat sandals for the boat, something dry for the ride home
- Photo ID, since some boats card at check-in for the bar
- Swimsuit, only if you've booked the Turtles, Pizza Pi & Sunset Sail
A short note on two items above: gratuities aren't included on any of the six cruises, and the crews work hard keeping drinks and appetizers moving all evening, so budget accordingly when you decide how much cash to bring. And unless you've booked the Turtles, Pizza Pi & Sunset Sail, you can skip the swimsuit entirely. Every other cruise on this list stays dry from the rail.
What St. Thomas Sunset Cruises Provide (So You Don't Overpack)
Every cruise we compare on the homepage already covers more than most travelers expect, which is why the list above stays short. Here's exactly what's handled for you versus what's genuinely on you:
| Item | Usually Provided | Bring Your Own | Notes |
|---|---|---|---|
| Open bar | Yes | Not needed | Rum punch, painkillers, wine and a champagne toast are included on all six cruises |
| Food | Yes | Not needed | Heavy appetizers on the standard sails; a full BBQ or taco dinner on the Sunset & Harbor Lights Dinner Sail |
| Champagne toast | Yes | Not needed | Every cruise times a toast to the moment the sun drops |
| Life jackets | Yes | Not needed | Stowed aboard, the crew points them out at boarding |
| Deck and cabin seating | Yes | Not needed | Covered seating on the larger catamarans, open rail seats on all of them |
| Charcuterie spread | Only on one cruise | Not needed | The Luxury Semi-Private Champagne Sunset swaps heavy appetizers for a charcuterie board |
| Snorkel gear | Only on one cruise | Not needed | Masks and fins come with the Turtles, Pizza Pi & Sunset Sail; the five evening-only sails don't involve swimming |
| Reef-safe sunscreen | No | Bring your own | None of the six cruises supply sunscreen |
| Warm layer for after dark | No | Bring a light layer | Every boat leaves this one to you, and it's the single most forgotten item |
| Towel | No | Bring one if you're snorkeling | Only relevant on the full-day sail |
| Gratuity | No | Bring cash | Suggested, not included, on every cruise |
| Phone or camera protection | No | Bring a dry pouch if you have one | Spray at the rail is common on the open-water catamarans |
What NOT to Wear or Bring
A short list, sourced from what the crews here actually ask guests to skip:
- Heels or an unsecured sandal: no grip on a moving deck, and the sea keeps whatever slides off the rail
- Cotton head to toe: it soaks up spray and stays damp for the rest of the ride
- Jewelry you'd hate to lose: rings and chains work loose at the rail more often than people expect
- Glass containers: every open bar on these boats pours into plastic cups or cans
- Heavy cologne or perfume: the mosquitoes at the marina notice before the boat even leaves the dock
- A second outfit you don't need: the dress code stays casual from check-in to the dock at the end
- Anything you can't afford to get wet: spray reaches the open rail seats on every one of these sails
Dressing for the Full-Day Turtles, Pizza Pi & Sunset Sail
The Turtles, Pizza Pi & Sunset Sail is the one cruise on this list that asks you to dress for two different parts of the day in one bag. The morning and early afternoon are built around an actual snorkel stop and lunch at the floating Pizza Pi boat, so a swimsuit under quick-dry shorts or a rash guard is the right start. As the day turns toward the sunset leg, most guests change into a dry shirt or cover-up for the ride home, since the six-hour outing runs long enough that the water portion is well behind you by the time the light turns gold.
Pack the swimsuit, the reef-safe sunscreen, and one dry layer, and you're covered for the whole day, not just the sunset at the end of it.
Packing by Season in St. Thomas
St. Thomas doesn't ask much of your suitcase by season, which is part of what makes the island easy to pack for. Air temperatures hold in the upper 70s to mid-80s year round and water stays a steady 79 to 84°F, so the beach-casual clothes and one light layer above work equally well in January and in July. The real shift is how soon you'll want that layer on: during the calmest, clearest months of April through June, warm evenings mean the layer often stays in your bag until the boat is well underway.
During the cooler stretch from December through March, St. Thomas's peak season, evenings run a few degrees cooler and the breeze off open water bites sooner, so plan to have that layer within reach from the moment you board. For the fuller month-by-month breakdown of sunset timing and sailing conditions, see our guide to the best time for a sunset cruise in St. Thomas.
What to Wear on a Sunset Cruise: FAQ
Can I wear jeans on a St. Thomas sunset cruise?
Better not to. Jeans don't dry once sea spray or a splashed drink hits them, and wet denim chafes and stays heavy for the rest of the ride. Shorts or a light dress handle the same evening far better.
Can I wear shorts on a sunset cruise?
Yes, and most guests do. Quick-dry shorts hold up better than cotton if spray reaches the rail, but any pair you're comfortable in works for the beach-casual dress code these cruises share.
Will I get wet on a sunset cruise in St. Thomas?
Only lightly, and only at the rail. These are calm, protected-water sails, not open-ocean crossings, so most guests stay completely dry the whole way. The occasional splash of spray is the real risk, which is why quick-dry fabric beats cotton.
Do I need water shoes for a sunset cruise?
No, not for the five evening-only sails. Flat sandals or bare feet on deck cover it. Water shoes only matter on the Turtles, Pizza Pi & Sunset Sail, and even there the snorkel entry is a sandy one, not rocky.
Is there a dress code for the dinner cruise or the semi-private charter?
No stricter than the rest. The Sunset & Harbor Lights Dinner Sail and the semi-private charter both stay beach-casual, though plenty of guests use the dinner cruise as an excuse to dress a little nicer than a t-shirt and shorts, entirely optional.
What should I definitely not bring on a sunset cruise?
Skip heels, an unsecured flip-flop, glass containers and anything you'd hate to lose overboard. Beyond that, the packing list here is short by design.
Pack light for a St. Thomas sunset cruise: beach-casual clothes, one layer for after dark, flat shoes, reef-safe sunscreen, and a little cash for the crew. Every boat already handles the drinks, the food and the champagne toast, so the short list above is genuinely everything left for you to think about before you board.
