Understanding Cartagena's Climate
Cartagena sits just 10 degrees north of the equator on Colombia's Caribbean coast, which means it's warm — often hot — year-round. Average temperatures hover between 27–32°C (81–90°F) regardless of the season. What changes dramatically throughout the year is rainfall, humidity, crowds, and prices. Understanding these patterns will help you plan a trip that matches your priorities.
The Two Main Seasons
Dry Season (December – April)
This is Cartagena's high season. Rainfall is minimal, breezes off the Caribbean keep temperatures slightly more comfortable, and the city is at its most photogenic. The water around the Rosario Islands is calmest and clearest during this period, making it ideal for beach day trips and snorkeling.
The tradeoffs: hotels are more expensive, the most popular tourist sites are more crowded, and booking accommodation well in advance is essential — especially around the Christmas–New Year period and Colombian Carnival in February/March.
Wet Season (May – November)
Cartagena's rainy season brings daily afternoon showers, higher humidity, and noticeably fewer tourists. This is the low season, and it comes with real advantages: lower hotel rates, quieter streets, and a more relaxed pace. The rain typically comes in intense but short bursts rather than all-day drizzle — meaning mornings are often clear and sunny.
October and November are the wettest months and can see rough sea conditions, making boat trips to the islands less reliable. The Walled City and Getsemaní, however, are perfectly enjoyable even in the rainy season.

Special Events Worth Planning Around
- Carnaval de Cartagena (November 11): Independence Day celebrations include parades, music, and the crowning of the Cartagena beauty queens — a deeply local celebration.
- Hay Festival Cartagena (January): A world-class literary and ideas festival that draws authors, thinkers, and artists from across the globe — surprisingly fun even if you're not a book lover.
- Colombian Carnival (February/March): While Barranquilla hosts the biggest carnival, Cartagena also celebrates with street parties and cultural events.
- Semana Santa (April): Holy Week brings religious processions through the Walled City and is a culturally rich time to visit, though hotels fill up quickly.
The Verdict: When Should You Go?
For first-time visitors who want the full Caribbean beach experience: aim for January through March. For budget travelers or those who prefer a quieter, more local atmosphere: May through July offers excellent value and a very livable rainy season. Avoid October if beach days are a priority.
