Key Takeaways: When to Book a Cartagena Boat Tour
- High season runs December, January, the week of Semana Santa, July, August, and November.
- December–February brings steady breezes. The sea stays fully navigable — you'll just feel it more. A bigger boat (catamaran-class) is the more comfortable call with kids or anyone prone to motion sickness.
- February–June is the calmest, quietest window — settled seas and the least traffic out at the islands.
- October & November are the rain months, but showers are short — about 30 minutes, usually in the morning — and a 9am departure typically sails through before it clears.
- Cartagena sits outside the Caribbean hurricane belt — unlike Cancún and Miami — so hurricane season isn't a planning factor for a charter here.
- Private Cartagena charter from $680 (Full Day), captain, fuel, and personal accident insurance included → Book at Nauty 360.
Cartagena de Indias sits on Colombia's Caribbean coast, its colonial walled city opening onto a bay dotted with mangrove islands, coral reefs, and the Rosario archipelago just offshore. A private charter here means DIMAR-licensed captains, a fixed departure schedule, and — unlike much of the Caribbean — a coastline that's rarely in a hurricane's path.
Sea conditions, rainfall, and how many other boats you'll share the islands with all shift across Cartagena's calendar. This guide breaks the year down month by month, using eight years of on-the-water operating data, so you can pick the window that fits what you're after.
Cartagena's Weather Windows at a Glance
The breezy stretch (December–February) is when Cartagena's trade winds are most noticeable. The sea stays fully navigable — this isn't rough water — but you'll feel the breeze more than the rest of the year. It also happens to overlap with the busiest weeks of high season, so a larger, more stable boat (catamaran-class) is worth requesting if you're traveling with kids or anyone sensitive to motion. By February, conditions are already easing toward the calm stretch that follows.
The calm stretch (March–September) is when the sea is generally settled for boating. Within that window, February through June stands out further still: calm water paired with the quietest islands of the year, before July and August bring high season's bigger crowds back — still on calm seas, just busier docks.
The rain stretch (October–November) is Cartagena's rainy season, but it's not a washout. Showers are short — roughly 30 minutes — and usually fall in the morning. A Full Day charter departing at 9am typically sails through it before the sky clears for the rest of the day.
Hurricanes are a minor factor here. Cartagena sits outside the Caribbean hurricane belt, unlike Cancún and Miami — which is why hurricane season isn't a planning factor for a Cartagena charter.
Month-by-Month Breakdown
December, January & February — Breezy High Season
December and January are peak travel months in Cartagena, and they come with steady trade-wind breezes. The water is completely navigable — captains run this coastline year-round — but the breeze is noticeable enough that a bigger boat makes the ride more comfortable, especially for kids or anyone prone to motion sickness. February keeps some of that breeze early on, then starts easing into the calmer months ahead, making it a good transition pick if you want lighter crowds with conditions trending toward settled.
March & April — Semana Santa's Peak Week
Outside of the week of Semana Santa (Holy Week, which lands in March or April depending on the year), these months sit inside Cartagena's calm-sea stretch. The Semana Santa week itself is high season — book ahead, since it draws the same demand as December and January without the breeze.
May & June — The Quiet Season's Best Stretch
May and June are part of the February–June window: calm seas and the fewest boats out at the islands all year. If your priority is having Isla Grande or the Rosario Islands to yourselves, this is the stretch to target.
July & August — High Season Returns
July and August are high season again — the sea stays calm, as it does through the whole March–September stretch, but demand climbs back up. Book ahead for these months the same way you would for December or January.
September — The Calm Stretch's Last Month
September closes out the March–September calm-sea window before the rain months begin. It isn't listed among Cartagena's high-season months, so it pairs settled water with lighter demand — a shoulder-season option worth considering.
Good to know: Every Nauty 360 Full Day charter runs a fixed 9am–5pm schedule. During the October–November rain window, that early departure is exactly what lets most charters sail past a brief morning shower and into a clear afternoon.
October & November — Short Morning Rain, Not a Washout
October and November are Cartagena's rain months. The showers themselves are brief — about 30 minutes — and tend to fall in the morning rather than spread across the day. A 9am Full Day departure typically clears the rain early and spends the rest of the day under open sky.
November carries a double identity: it's both a rain month and one of Cartagena's high-season months. The rain doesn't cancel that out — it's still considered one of the better months to visit, rain window included.
| Month | Season | Rain | Sea / Wind | Crowds | Recommendation |
|---|---|---|---|---|---|
| January | High | — | Steady breezes | — | Bigger boat with kids or motion-sensitive guests |
| February | — | — | Breezes easing toward calm | Low, quiet islands | Good transition month |
| March | High (Semana Santa week) | — | Calm | — | Book the Semana Santa week early |
| April | High (if Semana Santa falls here) | — | Calm | — | Same as March |
| May | — | — | Calm | Low, quiet islands | One of the best value windows |
| June | — | — | Calm | Low, quiet islands | Same as May |
| July | High | — | Calm | — | Book ahead |
| August | High | — | Calm | — | Book ahead |
| September | — | — | Calm (last month of the stretch) | — | Shoulder-season value |
| October | — | Short, ~30 min, usually morning | — | — | 9am Full Day sails past the rain |
| November | High | Short, ~30 min, usually morning | — | — | Rain month and high season at once — still a top pick |
| December | High | — | Steady breezes | — | Bigger boat with kids or motion-sensitive guests |
Cells marked "—" reflect no confirmed data for that month rather than an absence of the condition.
What a Private Charter in Cartagena Includes

Getting to the Islands: Navigation Times from Cartagena
The Rosario Islands are the closest offshore destination: about 45 to 55 minutes by lancha or yacht, and 1 hour 45 minutes to 2 hours 15 minutes by catamaran — the tradeoff for a slower, more stable ride. Isla Grande, part of the Rosario archipelago, has snorkel-friendly spots worth building into the day. For a longer trip, the San Bernardo Islands are available as a separate Full Day charter.
Which Season Is Right for Your Trip?
- Traveling with kids or anyone prone to motion sickness: December–February, and request a bigger boat (catamaran-class) for the breeze.
- Want the calmest water and the fewest other boats around: February through June.
- Don't mind a short morning shower for a better rate window: October and November — book a 9am Full Day so the rain clears early.
- Snorkeling is the priority: Isla Grande, on the way to the Rosario Islands, has snorkel-friendly spots.
- Traveling during December, January, Semana Santa week, July, August, or November: these are Cartagena's high-season months — book ahead.
The Hurricane Question: Why Cartagena Is Different
Hurricane season worries a lot of Caribbean travelers, and reasonably so — but Cartagena isn't Cancún or Miami. The city sits outside the Caribbean hurricane belt that regularly affects the Mexican Caribbean coast and South Florida, which is what keeps hurricane season from being a planning factor for a Cartagena charter. It's one of the reasons a Cartagena charter can be booked with more confidence across more of the calendar than other Caribbean destinations.
Practical Tips for Booking a Cartagena Boat Tour
- The Full Day charter has a fixed schedule: 9am to 5pm, 8 hours on the water. Plan your morning around that departure time.
- Traveling with kids, or anyone sensitive to motion? Request a bigger boat — catamaran-class — especially during the December–February breeze window.
- Booking during October or November? The rain is short and usually falls in the morning — a 9am departure typically sails past it.
- Every charter includes a DIMAR-licensed captain, fuel, and personal accident insurance — and there's no separate national park entrance fee to budget for.
- Want to snorkel? Isla Grande, part of the Rosario Islands, has snorkel-friendly spots.
