Visiting Colombia in September

September sits in the middle of Colombia’s longest rainy season, which runs from April through November across most of the Andes. That sounds like a deterrent, but the reality is more nuanced. The Caribbean coast stays warm and largely dry. The Pacific coast delivers some of the best humpback whale encounters of the year. And in the highlands, rain tends to fall in the afternoon, leaving mornings clear for hiking, exploring, and coffee region walks.

Prices in September are lower than at almost any other point in the year. Hotels that cost COP 300,000 a night in July often drop to COP 180,000-220,000. Domestic flight prices follow the same pattern. If you have flexibility and patience for some wet afternoons, September offers Colombia at a significant discount.

September Weather Across Colombia

Region	Avg High	Avg Low	Rain	Conditions
Bogota	17C	8C	High	Frequent afternoon showers, cool
Medellin	24C	17C	High	Mild temps, afternoon rain
Cartagena	32C	24C	Moderate	Warm, occasional showers
Cali	27C	19C	High	Rainy season, warm
Santa Marta	34C	27C	Low	Hot and mostly dry
Coffee Region	22C	14C	High	Lush but wet afternoons
Pacific Coast (Nuqui/Bahia Malaga)	28C	22C	Very High	Peak whale season

The pattern is consistent: mornings are frequently clear, afternoons cloud over, rain arrives between 2pm and 5pm, and evenings often clear again. Plan your outdoor activities in the morning.

What’s Happening in September

Humpback Whale Watching (Pacific Coast)

September is the peak month for humpback whale watching on the Colombian Pacific coast. The whales migrate from Antarctic waters and gather in the warm bays around Nuqui and Bahia Malaga between June and October, with numbers highest from August through September.

Tours depart from Nuqui and from the port of Buenaventura toward Bahia Malaga. Day trips from Nuqui run approximately COP 120,000-180,000 per person as of 2026. Multi-day packages including accommodation in ecolodges cost approximately COP 600,000-900,000 per person for 3 nights. Operators to look for include El Almejal Ecolodge and Playa Cocalito (Nuqui area). Book at least 2-3 weeks ahead for September trips.

Getting to Nuqui requires a 40-minute flight from Medellin on Sarpa or similar regional carrier, approximately COP 280,000-380,000 one way as of 2026. Bahia Malaga is accessible by boat from Buenaventura, 2 hours.

Feria de las Colonias - Leticia (September)

Leticia, Colombia’s Amazon gateway city, holds the Feria de las Colonias festival in mid-September each year. The festival celebrates the diverse Amazonian communities, featuring traditional Indigenous dances, artisan markets, food stalls selling river fish dishes, and flotilla parades on the Amazon River. Admission to most events is free. Leticia is accessible by direct flight from Bogota (approximately COP 450,000-700,000 return as of 2026).

Iberoamerican Theater Festival Bogota (biennial - even years only)

Bogota’s Iberoamerican Theater Festival runs every other year in March-April, not September. Check local listings if you want to coincide with performing arts events in September. The Teatro Colon in La Candelaria hosts regular opera and classical performances throughout the year (tickets from COP 30,000-120,000).

Best Places to Visit in September

Cartagena

The Caribbean coast around Cartagena receives significantly less rain than the Andes in September. The old walled city, Bocagrande beach, and the Rosario Islands are all accessible. While heat and humidity are high, the architecture and culture don’t require sunshine to enjoy. Boat trips to Isla Baru and the Rosario Islands run approximately COP 60,000-100,000 per person as of 2026 for day tours. Hotels in the old city: Hotel Casa del Curato (doubles from approximately COP 250,000/night), Hotel LM (from approximately COP 400,000/night).

Cartagena restaurants to try in September:

• La Cevicheria, Calle Stuart 7-14 - fresh ceviche, approximately COP 45,000-75,000 per dish
• El Boliche, Bocagrande - classic seafood, approximately COP 60,000-100,000 per person

Santa Marta and Tayrona

Santa Marta is the driest major city in Colombia in September and a good base. Tayrona National Park - a 1-hour drive from Santa Marta - sees lower visitor numbers than in December or January. Entry to Tayrona costs approximately COP 59,000 per person for nationals and COP 75,000 for foreigners as of 2026. The hike to Cabo San Juan takes 2-3 hours from El Zaino entrance.

Stay: La Casa del Farol, Santa Marta (doubles from approximately COP 200,000/night); Ecohabs Tayrona within the park (from approximately COP 450,000/night for a cabin).

Coffee Region

The coffee region - particularly Salento, Filandia, and Montenegro - is lush and green in September. Cocora Valley wax palms look their best after months of rain. The trails are muddier than in dry season, so waterproof boots and layers are essential. Coffee farm tours at Finca El Ocaso (Salento) cost approximately COP 30,000-40,000 per person and run through light rain.

Stay in Salento: Finca Bambusa (from approximately COP 130,000/night double), La Serrana Eco Farm (from approximately COP 200,000/night).

Eat in Salento: La Eliana, Calle Real - trout (trucha) dishes approximately COP 30,000-45,000.

What to Skip in September

The Andes for hiking: Trails on El Cocuy, Los Nevados, and other high-altitude parks are at their muddiest. Fog reduces visibility. The best trekking windows in these parks are December-February and June-July. Skip high-altitude multi-day treks unless you have waterproof gear and low expectations for views.

San Andres Island: September falls in the Caribbean hurricane season. While direct hits are rare, swells and choppy seas affect the famous Blue Hole diving conditions. January-April is better for San Andres.

Packing List for September in Colombia

Always:

• Light rain jacket or poncho (mandatory for Andes and coffee region)
• Quick-dry clothes - cotton stays wet for hours in high humidity
• Waterproof day bag cover
• Reef-safe sunscreen (essential even on cloudy days)
• Insect repellent (dengue season is year-round in low-altitude areas)

For Pacific coast / whale watching:

• Motion sickness tablets (boat trips can be rough in whale season swells)
• Waterproof dry bag for camera gear
• Light layers for ecolodge evenings (Pacific coast nights cool quickly)

For Bogota and the highlands:

• Fleece or light jacket - Bogota rarely exceeds 17C in September
• Waterproof hiking boots if planning Cocora Valley or similar trails
• Umbrella (afternoon showers are predictable - you’ll use it daily)

Leave behind:

• Heavy clothing - even Bogota rarely drops below 7C
• Expensive camera equipment if heading to the Pacific coast without waterproof protection

Budget Expectations for September

September is one of the cheapest months to visit Colombia. Expect to pay 20-35% less for hotels than in peak months (December-January, June-July). Budget travellers can manage COP 100,000-150,000 per day including accommodation in a hostel, local meals, and buses. Mid-range travellers spending on private rooms and some restaurants should budget approximately COP 300,000-500,000 per day. The Pacific coast whale-watching packages add cost - factor in approximately USD 100-180 per person per night at ecolodges as of 2026.
