Updated: March 2026
January is a good time to visit Cartagena (7/10). With 11 daily sunshine hours and only 2 rain days, this month delivers genuinely reliable outdoor conditions, ranking it the sunniest month of the year in Cartagena. Culture-focused travellers and those who prefer lighter crowds will find January a practical choice, with prices running lower than peak January without sacrificing all the good weather. February offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Cartagena's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.
Cartagena's January climate peaks at 32°C each afternoon before cooling to 24°C overnight. 11 daily sunshine hours and just 2 wet days mean the odds of a fine day are solidly in your favour. It is an excellent window for outdoor itineraries.

The 8°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. At 82% humidity, the 32°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. The UV index of 3 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Average wind speeds of 26 km/h add a meaningful windchill factor, making the 32°C temperature feel cooler than it reads. In Fahrenheit: 90°F average high, 75°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).
Packing for Cartagena in January means dressing for 32°C days and 24°C evenings. A lightweight linen or cotton shirt with loose-fit trousers or a sundress handles the 32°C daytime heat. Evening temperatures settle at 24°C, a modest 8°C drop that a light cardigan or denim jacket covers. For footwear, breathable walking sandals work for casual exploration, but closed-toe trainers are better for uneven surfaces in the historic centre. At 82% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Layers are more practical than a single heavy garment in Cartagena. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
January has no major festivals or public holidays in Cartagena, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
Based on 32°C average highs and 2 rainy days
In January, Cartagena sits in the dry season corridor, as the ITCZ shifts away from the region and trade winds bring drier, more stable air. This produces reliably sunny days reaching 32°C, with lower humidity than the wet months. Overnight lows of 24°C offer a pleasant reprieve from the midday heat. Climate data: Open-Meteo ERA5 (1991–2020).
Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
Humidity
Relative humidity as a percentage. Below 40%: Dry, skin and throat may feel parched. 40-60%: Comfortable, ideal for most people. 60-80%: Sticky, light breathable fabrics recommended. Above 80%: Muggy, heat feels more intense; quick-dry clothing is essential.
