Cartagena Weather March: 7 Things to Know Before You Go

Are you planning a trip to the Caribbean and are you wondering what the weather will be like when you arrive? The weather is warm, sunny and somewhat dry during Cartagena Weather March, which is why it is one of the most popular times to explore the Walled City, relax by the sea and head out for a day trip to the Rosario Islands.

The daytime temperature is generally around 30-31°C (86-88°F) while the evening is still warm and around 25-26°C (77-79°F). It may rain, but March is much drier than the rainy seasons of Cartagena. Planning activities on the Caribbean Sea can be subject to change in sunshine, rainfall and wind from one year to the next and even from one day to the next.

When searching what is the weather like in Cartagena Colombia in March, here are seven things you need to know before you start packing.

1. Cartagena Weather March Is Hot From Morning to Night

You will not need to pack for cool weather. Historical March data indicates that the average temperatures for Cartagena are around 31°C (88°F) during the day and near 26°C (79°F) at night, with an average near 28°C (82°F). The first thing to know if you are researching March weather in Cartagena Colombia is that there is not a huge difference between the temperatures at night and during the day.

Cartagena is warm even after dark. Tropical temperatures are higher in the middle of the day when the sun is shining directly. You will notice this most when walking around the Walled City, climbing Castillo San Felipe de Barajas or exploring streets with limited shade. A few simple Cartagena travel tips can make your day much more comfortable:

• Visit historic sites in the early morning.

• Always bring water with you when you are walking through the City.

• Avoid wearing bulky clothes.

• Apply sunscreen even if it is cloudy.

• Schedule slower activities for the hottest part of the day.

• Go out for sightseeing at the end of the day.

For a practical travel perspective of weather Cartagena March conditions, you must consider hot days, warm evenings and not much need for additional layers. 

What Does the Heat Actually Feel Like?

You can feel the humidity especially if you were strolling down the bustling streets of Cartagena during the peak of the day. You may find it heavier away from the water, and more comfortable areas near the Caribbean, which are more likely to enjoy the sea breeze.

That's why spending half an afternoon on the water can be a great idea. The open-air space and coastal breeze give you all the sunny and warm benefits, but with a more refreshing vibe. 

2. Cartagena Weather Trends From 2022 to 2026 Show Consistent Heat but Variable Rain

Monthly averages show you what you can expect, but historical records provide you with an understanding of how much one March day can vary from another.

WeatherAPI's historical Cartagena March records indicate that Cartagena weather March was relatively stable from 2022 to 2026, while precipitation levels were more variable from one year to the next.

The most important thing to remember is that there was no particular year that was better. It's the fact that March temperatures were rather steady, the average highs only fluctuated by roughly 1°C over those five years. Rainfall was much less predictable. 

March 2022 recorded 23.6 mm, while March 2023 recorded only 8.4 mm. It is for this reason that a monthly climate average can be useful for planning, but should not be used as a travel date guarantee.

Five years of weather observations are also far too short to establish a reliable long-term climate trend. Check an up-to-date forecast just before you travel, and use these figures as recent context. 

Did You Know?

WeatherAPI's records show that March 2022 had about 15.2 mm more rain than March 2023, despite having almost the same average high temperature during the day. It's a good reminder that Cartagena Colombia weather March can stay hot and dry and varies from year to year in precipitation. 

3. March Is Relatively Dry, but Rain Is Still Possible

If rain is a major concern, March is an excellent month to visit. The March long term average rainfall at Cartagena is relatively low compared to the wetter months of the year, and recent years indicate that there remains some scatter.

In other words, Cartagena Weather March tends to be much drier than Cartagena's wettest months, but “dry season” does not mean rain is impossible. Tropical showers can still occur. The upside is if there is a rain icon on your weather app, it doesn't necessarily mean that you have to spend the whole day inside. Tropical weather can be localized and rapidly changing.

When you're looking for information about weather in Cartagena Colombia for March, pay attention to the hourly forecast in the days surrounding your trip, rather than basing your entire trip on an average for the month. 

Does It Rain All Day in March?

Usually, no. In Cartagena, rain is more likely to occur as a short tropical shower during March than as a continuous day of rain. If the sky is cloudy, look at the hourly weather forecast before making a complete change of plans.

These guides can help when comparing between months:

• Cartagena weather January: Rainfall is typically not a major concern in January, as it is usually a dry month.

• Cartagena weather February: February is also relatively dry with little rainfall as compared to other wetter months.

• Cartagena weather in August: There is more chance of rain during August than March which makes it more common.

• Cartagena weather in November: November can be considerably wetter, with more unsettled weather and more rain.

• Cartagena weather in December: December is generally a dry month, but a few showers may fall.

To get a full year-round picture, our cartagena weather guide fleshes out the month-by-month variations in rainfall and seasonality. It's important to keep in mind that Cartagena is warm year-round, but rainfall fluctuates significantly from month to month. 

4. March Can Be an Excellent Month for the Rosario Islands

This is what most guests will remember about their visit. Cartagena Weather March is a relatively good choice for days on the Caribbean when the weather is warm and the precipitation is relatively low, with the cooperation of the daily wind and sea conditions. The Rosario Islands are off the coast of Cartagena, and a favourite destination for those wishing to abandon the colonial streets for clear water, snorkeling and beach time. 

Can You Take a Boat to the Rosario Islands in March?

Generally, yes. But don't rely on air temperature as the only indicator for boating conditions. Once you're off the shore, wind, waves, visibility and local marine conditions are far more important.

A Private speedboat Rosario Island trip is a private way to explore the islands for smaller groups and couples. Travelling with more people? You can look at a private boat charter Rosario Island instead. Another option for friends or families who want to spend the day together is a Rosario Island group boat day. 

What About Swimming and Snorkeling?

Cold water is unlikely to be your main concern in tropical Cartagena. Your bigger consideration should be the day's marine forecast.

Before leaving, check:

• Wind speed

• Wave conditions

• Thunderstorm risk

• Visibility

• Departure conditions

• Your captain's advice

Just because the sun is shining doesn't mean the sea is perfectly still. 

Pro Tip

When visiting Cartagena and you want to explore the Rosario islands, make your trip to the islands early rather than late in the trip. This provides more flexibility if your operators need to reschedule or change the route due to wind and sea conditions.
