BES Islands September |

Why Visit in September?

A September holiday to Bonaire, Sint Eustatius and Saba offers a brilliant way to experience the Dutch Caribbean at a relaxed pace. These three special municipalities, often called the BES islands, each have a distinct character, yet they work wonderfully as a multi-country-style island escape. Expect warm weather, friendly communities and plenty of time to enjoy the sea.

September is part of the quieter season, so beaches, walking trails and waterfront restaurants are often less busy than during the winter months. The climate remains hot, with daytime temperatures generally around 30°C, while the sea is invitingly warm for swimming and snorkelling. It is worth checking the forecast before travelling, as September falls within the wider Atlantic hurricane season, although the islands sit outside the main hurricane belt more often than many Caribbean destinations.

Bonaire’s Underwater World

Bonaire is famous for its protected marine environment and is one of the Caribbean’s finest destinations for diving and snorkelling. The island’s calm, clear waters make it easy to discover coral gardens, sea turtles and bright reef fish, whether you are an experienced diver or trying snorkelling for the first time.

September is a good time to explore at your own pace. Hire a car or scooter and follow the coastline, stopping at marked shore-diving sites, quiet coves and the salt pans in the south. Look out for Bonaire’s pink flamingos, then finish the day with a relaxed meal in Kralendijk as the sun sets over the Caribbean.

History on Sint Eustatius

Sint Eustatius, affectionately known as Statia, is ideal for travellers who enjoy history, nature and a slower rhythm. The island played an important role in Caribbean trade, and its past can be seen around Oranjestad, where old ruins, stone warehouses and Fort Oranje overlook the sea.

Beyond the historic sites, the Quill volcano provides a memorable walk through lush forest. September can be warm and humid, so start early, carry plenty of water and allow time to enjoy the views. The island’s peaceful atmosphere makes it easy to spend an afternoon chatting with local people or watching boats pass offshore.

Saba’s Mountain Trails

Saba is the smallest and most rugged of the three islands, with steep slopes, traditional villages and superb walking routes. The climb towards Mount Scenery leads through changing vegetation, while the famous road into The Bottom reveals dramatic views and an insight into island life.

September is a rewarding month for exploring Saba, provided you plan around the heat and occasional showers. Wear sturdy footwear, take water and consider a local guide if you want to learn more about the plants, wildlife and history. After a walk, enjoy fresh seafood or a cool drink while looking out across the deep blue sea.

Planning Your Island Hop

A multi-country trip across the BES islands needs a little organisation because transport links can be limited and schedules may vary. Flights and boat services do not always run daily, so check connections carefully and leave some flexibility between islands. A travel specialist can help combine accommodation and transfers into a practical September itinerary.

Choose Bonaire for underwater adventures, Sint Eustatius for heritage and volcanic landscapes, and Saba for walking and dramatic scenery. Together, they offer a Caribbean holiday that feels personal, uncrowded and refreshingly different. September could be the perfect time to discover them before the busier winter season begins.
