Whale Watching and Kitesurfing: Seasonal Activities

Whale watching and kitesurfing are big in the Cook Islands. The whale watching season, from June to October is a seasonal activity that attracts visitors from around the world. During this time humpback whales migrate to the islands’ waters and you can see these magnificent creatures up close.

The Cook Islands have a tropical climate with two main seasons: dry and wet. The shoulder season, from April to June and September to December has pleasant weather, lower prices and fewer crowds. While the weather is good all year round, each season has its own experience for visitors.

Dry Season: April to November

The dry season, from April to November is the best time to visit the Cook Islands. During these months the weather is warm but not too hot, 77°F to 84°F (25°C to 29°C). This is the best time for beach time, snorkeling and exploring the islands without the humidity and rain of the wet season.

The driest months—July, August and September are the most popular with tourists from Australia and New Zealand and those looking to escape the cold. This is the peak season, so the islands will be busier especially in the popular spots like Aitutaki and Rarotonga. The Cook Islanders are used to the influx of tourists during this time and the islands are alive with events, cultural shows and festivities.

Wet Season: December to March

From December to March the Cook Islands have the wet season with more rain, higher humidity and more cyclones. Daytime temperatures during this time can still be warm, 77°F to 86°F (25°C to 30°C) but the rain can come in bursts and some outdoor activities are less predictable.

Although it’s the low season the wet season can still be a good time to visit the Cook Islands. Fewer tourists means the beaches, including the famous One Foot Island in Aitutaki Cook Islands are often empty, so you can have a peaceful and more secluded experience. The rain comes in short bursts so there’s plenty of sunshine in between. If you want to explore the island’s interior or do the famous Cross Island Trek on Rarotonga the wet season’s green landscape makes for great hiking.

If you’re a marine life lover this is the best time to visit the Cook Islands for whale encounters.

Kitesurfing Season: May to October

The Cook Islands, especially Muri Lagoon on Rarotonga are a kitesurfers paradise. The trade winds blow steadily from May to October so this is the best time to catch some air.
