Is July a Good Time to Visit Cartagena?

3/10

Avoid

July is a avoid time to visit Cartagena (3/10). With 7 daily sunshine hours and only 17 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 3rd sunniest of the year in Cartagena. July suits travellers visiting for indoor culture, food, and architecture rather than outdoor activities. Pack accordingly for 17 potential rain days. August offers a similar profile at lower hotel rates if dates are flexible. Watch out for prolonged rain stretches: with 17 wet days, a fully outdoor itinerary is risky. Build in museum days and covered market visits as contingency. Planning tips: most accommodation categories have availability, and last-minute deals are common. The quieter streets and shorter queues can make this a genuinely enjoyable time to visit for the right type of traveller. Budget-conscious visitors will find the best value of the year in this period.

Temperature in Cartagena in July

The 7°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.

Wind averages 15 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 90°F average high, 77°F overnight low.

Packing for Cartagena in July means dressing for 32°C days and 25°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 25°C, a modest 7°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. With 17 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. At 82% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.

💡

Local tip: Cartagena sees heavy rain periods where a compact travel umbrella can feel inadequate. A packable waterproof jacket offers better coverage for prolonged downpours and leaves both hands free for maps and cameras.

Why is Cartagena warm in July?

Cartagena's July climate is governed by the Inter-Tropical Convergence Zone (ITCZ), which draws moisture-laden trade winds across the region, producing the characteristic wet season rainfall of steamy tropical cities. Daytime heat peaks around 32°C, moderated slightly by afternoon convective showers. Overnight temperatures remain warm at 25°C because the humid air retains heat effectively. 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.
