Is It Cold at Sea on a Cruise Ship?

By Michael Ferguson

Taking a cruise is a great way to enjoy a vacation and explore the world. But one of the main questions that travelers have when planning a cruise is whether or not it will be cold at sea. It’s true that the weather can vary greatly depending on where you are, but there are some general rules of thumb that can help answer this question.

The temperature of the ocean water has a huge influence on the temperature of the air around it. The average surface temperature of the ocean is about 72°F (22°C). This means that if you’re cruising in waters with an average surface temperature of 72°F, then you’ll mostly likely experience temperatures in the range of 70-80°F (21-27°C).

Of course, temperatures can drop significantly depending on where you are and what time of year it is. In colder months, temperatures may dip as low as 50°F (10°C) in some parts of the world.

And even in warmer months, temperatures may drop to 60-65°F (15-18°C). So it’s important to keep this in mind when packing for your cruise.

Another factor to consider is wind chill. When travelling at high speeds or in windy conditions, you may experience a significant decrease in temperature, even if the air temperature itself isn’t that cold. This means that if you’re sailing on an exposed deck or during windy conditions, then it could feel much colder than expected.

Finally, it’s important to remember that most cruise ships will have heated areas such as indoor swimming pools and hot tubs for guests to enjoy should they get too cold outside. So no matter what kind of weather you encounter at sea, there will always be plenty of ways to warm up and stay comfortable throughout your voyage.


In conclusion, while temperatures at sea can vary greatly depending on where you are and what time of year it is, most cruises experience temperatures ranging from 70-80°F (21-27°C). However, wind chill and colder months can bring down temperatures as low as 50°F (10°C), so make sure to be prepared with appropriate clothing for any kind of weather!
