  A private boat trip is a great way to experience Lisbon with friends.

  Make your experience even more special with catering and other options on board.

September has a special way of extending summer in Lisbon.

The days are still warm, the light begins to take on the golden tones of late summer, and the Tagus River continues to invite you to spend a few hours on board.

For those visiting Lisbon at this time of year, or simply looking for something different to do in the city, taking a boat trip in Lisbon in September is a great way to enjoy the last days of summer away from the busy streets and see the city from a completely different perspective.

Whether it’s a sunset cruise, a celebration with friends or a private experience that takes you beyond the Tagus, September still offers excellent conditions for sailing.

Why Take a Boat Trip in Lisbon in September?

Although September marks the beginning of the transition into autumn, summer can still very much be felt in Lisbon.

Average daytime temperatures are around 26–27°C, and the days still offer plenty of daylight, creating great conditions for outdoor activities.

On board, that means enjoying the deck, raising a glass at sunset, celebrating a special occasion or simply relaxing as Lisbon unfolds around you.

And there’s another advantage: instead of discovering the city only through its streets and viewpoints, from the water you can admire some of Lisbon’s most iconic landmarks from a completely different perspective.

Lisbon Has a Different Charm from the Water

Departing from Lisbon, a cruise along the Tagus River offers a privileged view of some of the city’s most iconic landmarks.

Belém Tower, the Monument to the Discoveries, MAAT, the 25 de Abril Bridge, Cristo Rei and Lisbon’s waterfront all take on a different dimension when seen from the river.

But your experience doesn’t necessarily have to stay on the Tagus.

Depending on the experience you choose, its duration and sailing conditions, it’s possible to plan trips that continue along the coast, turning a few hours on board into a true day at sea.

That freedom is precisely what makes a private boat experience different: the boat is no longer simply a way to get around, it becomes part of the experience itself.

September Sunsets Are Even Better from the Water

Some days simply call for a sunset on board.

In September, sunset gradually gets earlier, from approximately 7:10 pm at the beginning of the month to around 6:20 pm towards the end. This makes it possible to enjoy the late afternoon and watch the light change over Lisbon without finishing your cruise too late.

As the sun goes down, the city changes colour, the lights along the waterfront begin to appear and the 25 de Abril Bridge takes on a completely different atmosphere.

With a drink in hand, music on board and Lisbon as your backdrop, it’s easy to understand why a sunset cruise is one of the most popular experiences on the river.

More Than a Boat Trip: An Experience Tailored to You

Not every group is looking for the same thing.

Some want a peaceful two-hour cruise along the Tagus. Others are celebrating a birthday. Some groups of friends want music and drinks on board, families are looking for a different way to spend an afternoon together, and companies choose a boat to bring their teams together outside the usual work environment.

At Royal Marine, our private boat experiences can be adapted to the occasion, with different options including catering, drinks, decoration, music, photography and other additional services, subject to availability.

You can also choose between different boats depending on the size of your group and the type of experience you have in mind. Our fleet can accommodate everything from smaller groups to larger events.

Lunch on Board? Absolutely.

A boat trip in September doesn’t have to be all about sunset.

If you have more time, a daytime experience allows you to combine sailing with food, drinks and, depending on the experience you choose, other activities on board.

Lunch with friends, a birthday celebration or simply a few hours away from your usual routine feel completely different when the backdrop is the river or the sea.

Royal Marine offers different catering options and, on selected experiences, guests can also bring their own food and drinks on board.

What If September Brings a Less-Than-Perfect Day?

Conditions at sea should always be respected.

Although September is generally still warm and relatively dry in Lisbon, weather and sailing conditions can vary.

For this reason, every experience should take into account the conditions on the day and the guidance of the crew. Safety and comfort always come first.

And on the right days, September can deliver those beautiful late-summer afternoons that make being on board completely worthwhile.
