Cartagena Weather by Month — The Essential 2026 Quick Guide
First, Cartagena weather follows a clear two-season pattern. Also, the dry season runs December through April. Furthermore, the rainy season runs September through October. As a result, every other month sits in transition — sometimes hot, sometimes wet, always Caribbean.
Additionally, temperature varies less than rain. Also, daytime highs hover between 87 and 91 Fahrenheit year-round. Therefore, the question is not “will it be warm” — it is “will it rain.” Above all, that single answer changes your packing list, your itinerary, and your photos.
Moreover, Cartagena humidity stays high year-round — typically 75 to 85 percent. As a result, the heat feels stronger than the thermometer suggests. Therefore, evening activities and shaded venues matter more here than in drier Caribbean destinations.
Finally, this guide breaks Cartagena weather down month by month. Also, it gives you the data Colombia Luxury Group concierges use when our guests ask “should I come in March or June?” Above all, the answer is rarely the same twice.
Where Cartagena Weather Comes From — Geography and Climate
Cartagena sits on Colombia’s northern Caribbean coast at 10 degrees latitude. As a result, it sits squarely in the tropics. Furthermore, the city has no real “winter” or “summer” — the sun stays high year-round and daylight runs roughly 12 hours every month.
Also, Cartagena weather is shaped by the trade winds. Specifically, Atlantic trade winds blow steadily December through April. Therefore, those months feel cooler, drier, and breezier. Conversely, when the trade winds weaken in autumn, humidity rises and rain arrives.
Additionally, the Caribbean Sea moderates extremes. Also, the water temperature stays between 79 and 84 Fahrenheit all year. Therefore, swimming is comfortable any month. As a result, beach days are never weather-blocked the way they would be in a temperate destination.
Furthermore, Cartagena sits outside the main hurricane corridor. Also, direct hurricane hits are rare — the southern Caribbean coast is sheltered by Colombia’s mainland geography. Therefore, even in peak Atlantic hurricane season (August through October), Cartagena rarely experiences a direct strike.
Month-by-Month Cartagena Weather Breakdown
January. Peak dry season. Highs 88-90F, lows 75-77F. Rain extremely rare — typically 1-2 days the entire month. Trade winds strongest. Humidity drops to 70-75 percent. As a result, January is the single most-requested month for CLG bookings. Above all, weddings, yacht charters, and outdoor events all peak this month.
February. Dry season continues. Highs 88-91F, lows 76-78F. Rain almost unheard of. Also, February sees heavy hen-do and bachelor-party traffic. Therefore, book yacht charters and top restaurants 4-6 weeks ahead.
March. End of peak dry season. Highs 89-91F, lows 76-78F. Trade winds start easing. Furthermore, Holy Week (Semana Santa) often falls in March or April — Colombian domestic tourism spikes during this period. Therefore, accommodation prices climb and reservations tighten.
April. Transition month. Highs 89-92F, lows 77-79F. First scattered rain showers begin late April. Also, humidity climbs back toward 80 percent. Above all, April mornings and early afternoons stay reliably dry — afternoon thunderstorms become possible by month’s end.
May. Shoulder season begins. Highs 89-91F, lows 77-79F. Brief afternoon thunderstorms 5-8 days. Furthermore, May offers the best combination of warm water, sunny mornings, and lower hotel rates. Therefore, savvy travelers target this month for value.
June. Light rainy season. Highs 88-90F, lows 76-78F. Rain on roughly 8-10 days, mostly brief afternoon storms followed by clearing. Also, mornings remain reliably sunny. Above all, June is the secret month — peak weather quality at off-peak prices.
July. Mid-year mini dry spell. Highs 88-91F, lows 76-78F. Rain frequency drops to 5-7 days. Furthermore, this is the “veranillo de San Juan” — a brief dry window that catches even locals by surprise. Therefore, July is an underrated travel month.
August. Rain picks up again. Highs 88-91F, lows 76-78F. Rain on 9-12 days. Also, humidity 80-85 percent. Therefore, August is hot and sticky. Conversely, sea conditions stay calm and yacht days remain viable.
September. Peak rainy season begins. Highs 88-90F, lows 76-78F. Rain on 12-16 days, often heavy. Furthermore, lightning storms are common in late afternoon. As a result, outdoor weddings and ceremonies require contingency planning.
October. Wettest month of the year. Highs 87-89F, lows 75-77F. Rain on 14-18 days. Also, full-day rain events become possible. Therefore, October is the only month CLG concierges actively warn guests about. Above all, indoor and covered venues are essential during this window.
November. Rainy season ends. Highs 88-90F, lows 76-78F. Rain frequency drops sharply mid-month. Furthermore, late November returns to typical 5-7 rainy days. Therefore, late November is excellent for shoulder-season weddings — dry weather returns, prices stay moderate.
December. Dry season returns. Highs 88-90F, lows 75-77F. Rain rare. Also, trade winds rebuild. Therefore, December joins January as the absolute peak month. Above all, late December (Christmas through New Year) commands the highest prices of the year and books out 6+ months ahead.
Best Months for Specific Cartagena Activities
For yacht charters and Rosario Islands day trips: December through April. Also, calm seas, clear water, and reliable sunshine. Furthermore, this window delivers the photographs every visitor hopes for. Therefore, build the rest of your itinerary around yacht days during these months.
For Old Town walking tours and outdoor sightseeing: same window plus November and May. As a result, the cooler trade-wind months make 2-3 hour outdoor tours genuinely pleasant rather than punishing.
For destination weddings: January through April for peak reliability. Also, late November and December also work well. Furthermore, June and July offer good weather at lower prices for couples comfortable with brief afternoon rain risk. Above all, avoid September and October unless you commit to fully covered indoor venues.
For budget travel: May through July. Also, late August. Therefore, hotels and yacht rates drop 15-30 percent. Furthermore, the weather quality during this window is genuinely good — only the rain frequency rises modestly.
For festivals and cultural events: late January (Hay Festival), late March or April (Semana Santa), and November (Cartagena Independence Day). As a result, these dates combine reliable weather with major cultural programming. However, they also trigger price spikes and reservation difficulty.
Cartagena vs Other Caribbean Destinations — Weather Comparison
Cartagena vs Cancun: Cancun sits in the Atlantic hurricane corridor. As a result, August through October presents real hurricane risk in Cancun that Cartagena largely avoids. Furthermore, Cancun temperatures swing wider — slightly cooler in winter, slightly hotter in summer.
Cartagena vs Punta Cana: similar trade-wind influence, similar dry-season pattern. Also, Punta Cana receives more rain year-round on average. Therefore, Cartagena offers slightly more reliable weather during shoulder months.
Cartagena vs Aruba: Aruba is drier overall — situated in the southern Caribbean rain shadow. As a result, Aruba is the better choice for travelers who require zero rain risk. Conversely, Cartagena offers richer cultural and culinary experiences alongside its beaches.
Cartagena vs Caribbean Mexico (Tulum, Playa del Carmen): Cartagena humidity is comparable, temperature slightly higher year-round. Also, Cartagena rainy season peaks two months earlier (September-October vs Tulum’s October-November). Therefore, the optimal travel windows differ — December-April overlaps for both, but May and November-early December favor Cartagena.
Why CLG Plans Around Cartagena Weather
Colombia Luxury Group has operated in Cartagena since 2012. As a result, our concierges have planned thousands of trips across every month of the calendar. Furthermore, we know which venues stay reliable in shoulder-season rain, which yacht captains pull anchor early when weather turns, and which indoor restaurants make your group forget the storm outside.
Also, we plan contingencies into every booking. Therefore, our June or September guests receive itineraries with rain-resilient backup options at every step. Above all, weather rarely ruins a CLG-planned trip — because the planning anticipated it.
Furthermore, our pricing reflects the season. Also, we share which months offer the best weather-to-price ratio honestly during the planning call.

Conversely, guests who need iron-clad weather (weddings, milestone celebrations, outdoor photography) get steered to December through April.
Above all, we treat Cartagena weather as a planning input, not an afterthought. As a result, our guests rarely experience the weather-related disappointments that derail unplanned trips.

Cartagena Weather: A Month-by-Month Snapshot
Below is the practical month-by-month breakdown CLG concierges hand to clients planning trips. Temperatures hold steady year-round; the variables that matter for luxury travel are humidity, rainfall, and crowd density.
December through April — Dry season, peak luxury window
December through April is the dry, breezy, low-humidity stretch. Daytime highs hover around 30°C, evenings drop to 24°C, and the trade winds keep yacht days comfortable. This is when CLG runs its highest booking volume and our partner villas hit peak occupancy. Reservations 8–12 weeks ahead are the rule for this window.
May through July — Shoulder transition
The dry season fades through May, with isolated afternoon rain returning. June and July are warm, occasionally rainy, but still very travel-friendly. Pricing starts to drop. CLG typically recommends shoulder months for clients who prefer fewer crowds and lower vendor pricing without sacrificing reliable yacht weather.
August through November — Rainy season
Rain peaks in October. Showers arrive as short intense bursts in the afternoon rather than all-day downpours, and yacht days remain viable with morning departures and flexible afternoon scheduling. Hotels and yachts run their lowest pricing of the year. Travelers comfortable with weather flexibility get the best rates of the calendar.
Packing for Cartagena Weather Year-Round
The packing list does not change much across seasons because temperatures stay consistent. The key adjustments are a light rain layer for shoulder and rainy seasons, sun protection year-round, and breathable fabrics regardless of month. Linen and cotton outperform synthetics in the Caribbean humidity. Reef-safe sunscreen is required for yacht days and Rosario Islands swims under local environmental rules.
Evenings rarely need more than a light shirt. Restaurant dress codes in Old Town tend toward smart-casual rather than formal — a linen shirt and chinos works for most luxury dinner reservations. Heels are difficult on Old City cobblestones; wedge sandals or low block heels are the practical choice for women.
How Weather Affects Yacht and Excursion Days
The Caribbean Sea around Cartagena stays warm and swimmable year-round, so yacht days work in every month. The factors that affect comfort are wind (highest December–March, ideal for sailing), wave height (calmest April–June), and afternoon visibility (best in dry season). CLG yacht concierges check the marine forecast 48 hours before each charter and will recommend timing adjustments or itinerary changes if conditions warrant.
For destination weddings, photoshoots, and other date-locked events, dry-season dates buy you weather predictability. Shoulder and rainy season events still work — every CLG outdoor venue contract requires a covered backup option included in the booking — but the operational margin is thinner.
What is the best month weather-wise to visit Cartagena?
January through March is the sweet spot. Dry season is fully established, humidity drops to its annual low, daytime highs sit near 30°C with a steady Caribbean trade wind. December and April come close, with December busier from holiday tourism and April slightly more humid as the season transitions.
When is rainy season in Cartagena?
The rainy season runs from late August through early November, with October as the peak rain month. Rain typically arrives as short intense afternoon showers rather than all-day downpours, so morning excursions and yacht days remain viable with flexible scheduling and CLG concierge support.
How hot does Cartagena get?
Cartagena temperatures hold steady year-round between 26°C and 32°C (79°F to 90°F). The bigger seasonal variable is humidity, which climbs significantly during the rainy season and drops in the dry months from December through April. Sea breezes moderate temperatures along the coastline year-round.
Is Cartagena humid?
Yes, Cartagena is consistently humid because of its Caribbean coastal position. Average relative humidity sits between 75% and 85% throughout the year. December through March feels noticeably less humid; September through November is the muggiest stretch. CLG hotels and villas offer climate-controlled comfort year-round.
What should I pack for Cartagena weather?
Pack lightweight breathable clothing in linen or cotton, a light rain layer for shoulder season, sun hat, reef-safe sunscreen, and water-friendly footwear. Evenings rarely require more than a light shirt, even in the dry months. CLG concierges share season-specific packing lists with each booking confirmation.
Does Cartagena get hurricanes?
Cartagena sits below the main Caribbean hurricane belt and almost never receives direct hurricane impact, making it a reliable year-round destination. Tropical storms occasionally bring elevated rain and wind during the August through November window but typically do not disrupt travel or yacht operations.
What is the temperature in Cartagena in December?
December averages 28°C daytime high and 24°C nighttime low. It marks the start of dry season — humidity drops, rainfall is minimal, and trade winds keep evenings comfortable. December is one of the most popular months for luxury travel; CLG recommends booking yachts and villas eight weeks ahead.
Can I swim year-round in Cartagena?
Yes, you can swim year-round in Cartagena. Caribbean water temperatures stay between 27°C and 29°C all year. Even during the rainy season the ocean is warm and swimmable. Beach days, snorkeling, and yacht excursions work in every month, weather permitting, with CLG providing flexible rescheduling on stormy afternoons.
