The short answer: October is Cartagena’s rainiest month, but that doesn’t make it a bad time to go. Showers are frequent, yet the heat and warm Caribbean water stick around, and outside of Colombia’s school break and the October 12 holiday weekend, the city is noticeably quieter than in high season. With a beachfront hotel that has pools, a restaurant, and places to relax when it rains, like Hotel Regatta Cartagena in Bocagrande, October can be one of the most laid-back ways to experience the city.
October has a bit of a reputation among people planning a Cartagena trip. And it’s not totally undeserved: it’s the wettest month of the year. But if you rule out October based on the forecast alone, you’ll miss a different side of Cartagena, with emptier streets, a Caribbean that’s just as warm, and a city you can enjoy without the December and January crowds.
The trick is knowing what to expect and planning around it. This guide covers what October weather is really like, the real upsides of going, and what to do when it rains and when the sun comes out.
What the weather is like in October
Cartagena has two clear seasons. The dry season runs from December through April, and the rainy season covers most of the rest of the year. October is the peak of the wet season: according to local maritime and weather records, it’s the month with the most rainfall in the city.
That doesn’t mean it rains all day, every day. In practice, October brings sunny mornings, changing skies, and heavy downpours that can last anywhere from a few minutes to a few hours. It’s still the Caribbean, with an average yearly temperature around 81°F, and the humidity is more noticeable than in other months.
What changes is how you plan. In October, it helps to have a morning plan, an indoor backup, and enough flexibility to move an excursion if the skies don’t cooperate. If you want to see how October stacks up against the rest of the year, this guide to the best time to visit Cartagena breaks it down month by month.
The real upsides of visiting in October
Fewer crowds, especially in the second half of the month
October is part of the low season. Outside of the local school break and the holiday weekend, the city sees far fewer visitors than in December, January, Easter week, or the summer vacation months. You’ll feel it in the Old Town, on the beaches, and when you try to get a table at a popular restaurant.
Low-season rates
With less demand, hotel rates and some tours tend to be more affordable than in high season. If your dates are flexible, October can put room types within reach that would be much harder to book in December.
The water is still warm
Rain doesn’t cool down the Caribbean. The water stays pleasant for swimming, and a sunny October day is just as good for the beach as any other time of year.
More dramatic sunsets
Rainy-season skies create some of the most striking sunsets of the year: heavy clouds, orange light, and reflections on the water after a storm. From an oceanfront room or terrace, they’re part of the appeal.
October 2026: school break and holiday weekend
The first half of October works differently from the rest of the month. In 2026, Colombia’s school break for most schools runs Monday, October 5, through Friday, October 9, and connects with the weekend and the Monday, October 12 national holiday. For many local families, that means up to ten days off in a row, with classes resuming on Tuesday, October 13.
During those days, Cartagena gets more domestic travelers, especially families. That same Monday is also Columbus Day and Indigenous Peoples’ Day in the U.S., so it’s a long weekend on both ends. If your trip falls in that window, book early. If you’re after peace and quiet and better rates, the second half of October is your best bet.
What to do in Cartagena in October when it’s sunny
Clear October days are perfect for enjoying the city without the crowds:
- Hit the beach early. Mornings are usually the best part of the day. Going between 7 and 10 a.m. means less heat and a lower chance of rain.
- Explore the Old Town. Wandering the Walled City with fewer tourists around is one of the biggest perks of the low season.
- Catch the sunset from the city walls. If the sky clears up in the afternoon, sunset from the walls is a Cartagena classic.
- Take a trip to the Rosario Islands. Boat trips depend on sea conditions. In October, book with flexibility and check conditions the day before.
What to do in Cartagena in October when it rains
Rain doesn’t have to ruin your day. Here are a few indoor options:
- Museums. The Old Town is packed with museums that dig into the city’s history, no weather worries required.
- Long Caribbean lunches. A slow lunch of local seafood is a great way to wait out a downpour.
- Shopping. Bocagrande’s malls and the Old Town’s craft shops make for an easy rainy afternoon.
- Hotel time. A rainy day is the perfect excuse for a massage, a nap, or an afternoon with a book and an ocean view.
Why your hotel matters more in October
In the dry season, your hotel is mostly where you sleep. In October, when you’re waiting out a storm or reshuffling plans on the fly, your hotel becomes a bigger part of the trip.
Hotel Regatta Cartagena sits on Avenida Malecón in Bocagrande, right on the beachfront. It has two pools on the 11th and 18th floors, a sun deck on the 18th floor, a spa, a restaurant, a bar, beach service, and a 24-hour front desk. Every room has A/C, and continental breakfast is included with every rate.
That mix works especially well in October: if the morning is clear, the beach is right across the street; if it rains, you’ve got a restaurant, a spa, and ocean-view rooms where you can watch the storm roll by. The Superior Room, with a direct view of the Caribbean, is a great pick for taking in those rainy-season sunsets without leaving the hotel.
What to pack for Cartagena in October
- Light, quick-dry clothing.
- A lightweight rain jacket or a compact umbrella.
- Sandals that can get wet.
- Sunscreen, even on cloudy days.
- Bug spray, which comes in handy during the rainy season.
- A waterproof pouch for your phone and documents on boat trips.
