What are the ABC Islands, and why do they lie outside the hurricane belt?
Aruba, Bonaire and Curaçao form the southernmost island group of the Caribbean, at around 12 to 13° north latitude and only 30 to 80 kilometres off Venezuela. This location puts them so close to the equator and so close to the South American mainland that hurricanes almost never form there or pass through — unlike further north in the Caribbean, hurricane season is barely felt here.
The Atlantic hurricane season, as defined by NOAA (National Hurricane Center), runs from 1 June to 30 November. According to NHC climatology, tropical cyclones usually form between 5 and 30° north latitude and generally track westward from there; but the actual core zone of storm formation lies considerably further north and east than the ABC Islands.
The physical reason why cyclones essentially never form right at the equator is the Coriolis force: it deflects air masses and produces a hurricane's characteristic rotation, but is zero at the equator and, according to NOAA's research division AOML, only becomes strong enough at around 300 miles (just under 500 km) from the equator. The ABC Islands, at over 1,300 km from the equator, are clearly beyond this threshold, but they sit at the very outer, south-westernmost edge of the whole storm-formation zone, right off the South American mainland.
What 'outside the hurricane belt' means in concrete terms is shown by an analysis of historical NOAA best-track data: in 168 years of records, not a single hurricane has made direct landfall on Aruba; the closest storm centres passed the island at a distance of 24 to 50 km, most recently a category-2 system in 1892. A hit is therefore not ruled out, but it remains statistically the exception.

How do Aruba, Bonaire and Curaçao differ from one another?
Aruba is the most heavily developed of the three for tourism, with wide sandy beaches and large resorts; Curaçao is the largest and culturally most diverse, with the UNESCO World Heritage city of Willemstad; and Bonaire is the smallest and least built-up, focused almost entirely on diving and nature conservation.
| Island | Area | Character | Currency | Own page |
|---|---|---|---|---|
| Aruba | 193 km² | resorts, wide beaches, windsurfing, carnival | Aruban florin (AWG) | yes |
| Curaçao | 444 km² | UNESCO old town Willemstad, shore diving, national parks | Caribbean guilder (XCG) | yes |
| Bonaire | 288 km² | marine national park, diving, little mass tourism | US dollar | not a separate page |
Since the dissolution of the Netherlands Antilles in 2010, Bonaire has been a special municipality of the Netherlands, not an independent country like Aruba and Curaçao, and since 2011 has therefore used the US dollar instead of its own Caribbean currency. This ties the island more closely to the European mother country than its two neighbours.
The linguistic difference shows even in the spelling: Aruba writes its creole language Papiamento with an etymological spelling close to Spanish and Portuguese, while Curaçao and Bonaire write Papiamentu phonetically – the same word for 'knife' becomes 'cuchiu' on Aruba and 'kuchú' on Curaçao and Bonaire.
The three islands also differ touristically: Aruba mainly attracts beach holidaymakers and families from the US and Latin America, Curaçao a mix of culture and diving travellers, while Bonaire caters almost exclusively to an international audience of experienced divers who can do without nightlife and large resorts.

When is the best time to visit the ABC Islands?
All three islands show a dry climate year-round with highs around 29 to 32 °C and little rain; the driest months are January to September, while October to December bring somewhat more rainfall. There is virtually no rainy-season pattern like elsewhere in the Caribbean.

Because hurricane season has almost no impact here, there is no pronounced storm-related low season as in the rest of the Caribbean; travellers choose their months based more on wind, water temperature or price.
The north-east trade wind blows almost year-round on all three islands, but is strongest between December and July – this makes Aruba in particular a reliable windsurfing and kitesurfing destination, while the sheltered south-west coasts of Curaçao and Bonaire offer calmer diving water.
Season makes almost no difference to water temperature: it stays between roughly 26 and 29 °C year-round, so diving and snorkelling are possible without a wetsuit at any time. Those looking for especially calm, wind-free days, for example for relaxed snorkelling or boat trips, have the best chances between August and November.

What distinguishes Aruba, Bonaire and Curaçao?
Aruba scores with long sandy beaches, Arikok National Park and a dense range of resorts; Curaçao with colourful Willemstad and reefs accessible directly from shore; Bonaire with one of the strictest marine protected areas in the Caribbean and dive sites reachable practically without a boat.
Aruba: beaches, wind and resorts
Aruba is the westernmost and most heavily developed of the three islands for tourism, with Palm Beach and Eagle Beach as hotel hubs and Arikok National Park, which protects almost 18 percent of the island as a desert and cave landscape.
The capital, Oranjestad, is also a cruise port; the former refinery town San Nicolas in the southeast has developed into an address for street art. Aruba has the largest hotel supply of the three islands and the best connections to North America.
Curaçao: World Heritage old town and shore diving
Curaçao is the largest of the three islands at 444 km² and stands out for the old town of Willemstad, listed as UNESCO World Heritage since 1997, and for reefs that are accessible directly from the beach in many spots.
Outside Willemstad, Christoffel Park in the northwest and the wave-battered Shete Boka National Park on the north coast shape the landscape; the uninhabited outlying island Klein Curaçao can be reached by boat as a day trip.
Bonaire: marine conservation instead of mass tourism
Bonaire, the smallest of the three islands with around 26,500 inhabitants, has no dedicated editorial page in this database, but touristically belongs inseparably to the ABC Islands: almost the entire coastline has been protected for decades as the Bonaire National Marine Park, with a strict anchoring ban and more than 350 fish species. The capital Kralendijk is the starting point for shore-diving tours, where divers carry their gear straight from the car into the water.
Unlike Aruba and Curaçao, Bonaire is not an independent island nation but has, since 2010, been a special municipality of the Netherlands – more directly tied to The Hague than its two neighbours, which also shows in the legal framework for nature conservation.
Those who can only choose one of the three islands usually orient themselves by the focus of the trip: Aruba for beach and family holidays, Curaçao for a mix of culture and water sports, Bonaire for concentrated diving without a big supporting programme. Anyone wanting to see all three should not leave the order to chance, but deliberately place Bonaire's leaner infrastructure at the end of the trip.

How can the ABC Islands be connected with one another?
Aruba, Bonaire and Curaçao are linked by several daily short-haul flights, so two or all three islands can be combined in a single trip. There is no ferry connection between the islands; switching between them is done exclusively by plane.
According to flight schedules, Aruba has nonstop connections to both Curaçao and Bonaire, so a round trip across all three islands can be planned entirely without a detour via a mainland destination.
A classic two-island route combines Aruba with Curaçao and, at four to five days per island, takes around ten days; those wanting to see all three islands should plan at least four to five additional days for Bonaire, given its infrastructure focused on diving.
| Route | Duration | Focus |
|---|---|---|
| Aruba + Curaçao | 9–12 days | beach, windsurfing, old town, shore diving |
| Curaçao + Bonaire | 9–12 days | diving, culture, national parks |
| Aruba + Bonaire + Curaçao | 14–18 days | a full overview of all three islands |
All day figures are editorial guidelines, not guaranteed trip lengths; flight schedules between the islands change seasonally.
For a two-island route, it is usually best to arrive on Aruba or Curaçao, since both are reachable nonstop from Amsterdam, followed by a short-haul flight to the second island; Bonaire thus becomes the actual endpoint of a round trip, not the starting point for arrival from Europe.

How do you get to the ABC Islands?
Aruba and Curaçao each have a nonstop connection to Europe via Amsterdam, while Bonaire can only be reached from Europe with a change of plane; from North America there are considerably more direct flights to all three islands, especially from Miami.
| Island | Airport | Nonstop from Europe | Nonstop from North America |
|---|---|---|---|
| Aruba | Queen Beatrix International (AUA) | Amsterdam (KLM) | over a dozen US cities, Toronto, Montreal |
| Curaçao | Curaçao International, Hato (CUR) | Amsterdam (KLM, Corendon, TUI fly) | Miami, Newark, Atlanta |
| Bonaire | Flamingo International (BON) | none, connection required | Miami, Newark, Houston |
Travellers from Asia, Africa, the Middle East or Oceania generally connect via Amsterdam or a North American hub such as Miami; the ABC Islands cannot be reached nonstop from there.
All three islands lie in the UTC−4 time zone with no daylight saving, so the time difference to Central Europe varies between five and six hours depending on European winter or summer time.

What applies for entry and health on the ABC Islands?
Swiss, German and Austrian citizens can enter all three islands visa-free for tourist stays of up to 90 days, but must fill out a separate digital entry card for each island: the ED-Card for Aruba, the DI-Card for Curaçao, and a comparable online registration for Bonaire. Health-wise, the picture is the same across all three islands: no malaria risk, but a year-round dengue, chikungunya and Zika risk from mosquitoes.
A yellow fever vaccination is not medically required on any of the three islands, but is required for anyone who left or transited a country with a yellow fever risk within the previous six days. healthytravel.ch recommends hepatitis A for all travellers on all three islands, and hepatitis B for risk groups.
The relevant authorities are the FDFA, the Federal Foreign Office and the BMEIA, as well as each island's own immigration authority. Different rules apply for other nationalities.
Basic medical care is solid on all three islands, but patients are frequently flown between the islands or to the United States for specialised treatment; travel health insurance with an evacuation clause is advisable on all three islands.

What does a trip to the ABC Islands cost, and which currencies apply?
All three islands have different currencies – the Aruban florin, the Caribbean guilder, and the US dollar on Bonaire – but the US dollar is additionally widely accepted everywhere, so currency exchange is rarely necessary. Price-wise, all three islands rank among the pricier Caribbean destinations.
Aruba tends to be considered the most expensive of the three islands, mainly because of the large hotel zone at Palm Beach; Curaçao is usually slightly cheaper, while Bonaire is also in the upper price bracket because of its limited supply of dive resorts.
Credit cards are common in hotels and larger restaurants on all three islands; on Bonaire, a cash reserve is advisable outside Kralendijk, since the business network is smaller than on Aruba or Curaçao.
In addition to accommodation costs, tourist-specific fees apply on all three islands, such as national park entry fees or a per-stay environmental levy; the exact amount changes frequently and should be checked before booking.
What culture connects the ABC Islands?
Papiamento or Papiamentu is the connecting cultural element of all three islands, one of the few creole languages in the world with official language status, blending Spanish, Portuguese, Dutch and West African roots.
Carnival is the biggest annual festival on all three islands, with its own parades, music competitions and the traditional burning of a symbolic figure at the close; the exact dates and customs differ from island to island in detail, but the basic pattern of weeks of preparation followed by a big closing parade is the same.
As part of the Kingdom of the Netherlands, all three islands also share the holiday for Dutch King's Day, while at the same time celebrating a pronounced local pride that clearly differs from the European part of the country in music, cuisine and language. Musically, tumba and kaha di orgel shape carnival, while in the kitchen, stuffed cheese, pastechi pastries and stews appear in similar forms on all three islands.
