Thanks to their tropical, oceanic climate, the Cook Islands enjoy pleasant temperatures all year round. On the other hand, there are wet and dry seasons. Depending on the season, rain can be abundant or the price of a trip can rise sharply. Discover the best time to visit the Cook Islands for an unforgettable vacation.

Visiting the Cook Islands During the Wet Season

Southern Summer: More Demanding Climatic Conditions

From November to early April, the Cook Islands experience a significantly warmer and, above all, much wetter period. This season is characterized by high temperatures, up to 31°C, and high humidity, with rains that are often brief but repeated and torrential. Weather changes are continuous, so it’s unlikely to escape the daily downpour. The sun shines, but the heat no longer evaporates at night: the air can quickly become stifling. The climax occurs in January and February.

The austral summer is also cyclone season. These more or less violent hurricanes strike the Cook Islands fairly frequently. They can have devastating effects, as was the case in 2005 when the archipelago was hit by five cyclones in almost a month. The tenfold force of the winds, deep tides and powerful waves ravaged crops, housing and infrastructure on many islands, including Rarotonga. Unfortunately, the phenomenon is becoming more widespread as a result of climate change.

A trip Away From the Tourist Circuit

The wet season is not the ideal time for a first trip to the Cook Islands. But there are a few consolations. Firstly, the period from January to March is an off-season for tourism. The low number of visitors means a considerable drop in the price of flights and, above all, accommodation. By avoiding vacation periods, it’s even possible to save large sums and enjoy the best hotels in Rarotonga at the same time.

An alternative in-between time would be to visit the Cook Islands in November. Fewer international visitors visit the archipelago, and you’ll have the impression of having beaches all to yourself. The waters are always warm, making for pleasant swimming and water sports. You’ll also discover a more authentic, less touristy way of life. At the end of the month, the unmissable Vaka Eiva competition takes place. For a whole week, crews from all over extended Polynesia compete in good-natured outrigger va’a canoe races.

Visiting the Cook Islands in the Dry Season

Snorkeling in the Cook Islands

June to September: the Beautiful Southern Winter

From May onwards, temperatures drop significantly, reaching an average of 25°C in July and August. The waters of the lagoons remain warm enough for snorkeling. Nights are also cooler, so you can sleep peacefully. Above all, the season is characterized by a drop in rainfall, still present but much more spaced out. As a result, humidity levels drop. The climate is ideal for island vacations.

July and August are the best time to visit the Cook Islands. It’s also high season for tourism, with international visitors arriving on Rarotonga and Aitutaki. Daily life is punctuated by numerous cultural events, while the tourist offer diversifies with mountain hikes and whale-watching. Overcrowding, however, is driving up accommodation prices. On the other hand, immersion can seem less complete, especially on the archipelago’s most popular islands. Leaving in September and October is a very satisfactory intermediate solution. You’ll enjoy more peace and quiet, lower prices and the same quality of service.

Te Maeva Nui Celebrations

From late July to August 4, the Cook Islands celebrate their autonomy with major cultural, sporting and political festivities. The local heritage is sublimated in a child-friendly atmosphere. The whole population is involved, especially the youngest. The arts and customs of the archipelago are showcased through dance, music, song and traditional crafts, as well as the promotion of the Maori language of the Cook Islands.

Hundreds of outer islanders converge on Rarotonga for the week-long national holiday, as do many international visitors, proof that the event is gaining in notoriety. Hotels and guesthouses are often fully booked, so travel plans for this time of year must be made well in advance. Nevertheless, the Te Maeva Nui celebrations are an essential part of the Cook Islands’ cultural calendar. As such, the 60th edition in 2025 promises to be grandiose!

Best Time to Visit the Cook Islands for You

July and August are the ideal time to visit the archipelago, with its highly satisfying cultural offerings and quality of accommodation. For greater tranquility without any loss of quality, you’ll want to leave in September or October. For a first trip to the South Pacific, it’s best to avoid the period from December to April. However, the southern summer also has its advantages: the beaches on the Cook Islands are sunny, the water temperature is deliciously warm and prices drop significantly.
