August is one of the coolest times of the year on the island. Daily average temperatures in this month range from a high of 25C (75F) to a low of 20C (68F), with an overall average of 23C (73F). These temperatures are similar to those in places such as Tahiti and Samoa. The average sea temperature in Rarotonga is 25C (77F) in August, some of the coolest temperatures all year but still suitable for water activities in the island's lagoon.

Sunshine Hours

You'll see the year's highest levels of sunshine in August with an average of 11 hours a day, just under the highs of 12 daily hours in September and October. While some clouds will hang over the centre of the island, the cover is minimal in August. 


August falls in the middle of Rarotonga's dry season (from June to October), so you can expect sunny skies if you arrive in this month. August has an average of 15 rainy days with an overall average rainfall of 70mm. The precipitation occurs during brief shows in the afternoons.


August is the least humid month on the island. The average relative humidity is 80%, with humidity of around 81% in the mornings and 72% in the evenings. 

Sunrise and Sunset

The duration of daylight is constantly increasing in August. On August 1, the sun comes up at 7:10 am and sets at 6:20 pm, giving the island 11:10 hours of daylight. On August 31, sunrise happens at 6:49 am and sundown takes place at 6:29 pm, with 11:40 hours of total daylight.

Wind Speed

You can expect moderate winds of 5.2 m/s in July, thanks to the trade winds that blow in from the east from May to October.

Extreme Weather

Falling outside the South Pacific's cyclone season that spans from November to April, August has little chance of seeing a major storm. The Cook Islands are less likely to get hit by tropical cyclones compared to countries such as New Zealand and Papua New Guinea. On the rare occasions that tropical cyclones hit Rarotonga, they can bring winds of up to 55 m/s (124 mph) and cause severe flooding.

Things to do in Rarotonga in August

Explore Rarotonga by Bike

Understandably, most visitors to Rarotonga focus on activities around its famed lagoon. But don't forget about land exploration. One of the best ways to traverse the island's diverse terrain is by bike. From easygoing rides around the island to plunging into adventure off-road, bicycle tours accommodate the wishes and skill levels of most riders. Hop on a bike and roll along ancient trails, through sweeping valleys and across wide plantations.

Take a Trip to the Highlands

While today most of Rarotonga's population lives along the coast, people in ancient times settled in the safer highland areas. Climb aboard an open-air transport to visit long-lost villages. Enjoy demonstrations of traditional cooking and coconut husking. Learn about the navigational stones used by ancient seafarers and visit gardens where ritual and medicinal plants grow. Cruise through the verdant valleys of Avatiu and up to lookout points with panoramic ocean views.

Head to the Harbours

In contrast to the serene snorkelling spots on Rarotonga's southern shore, the north side of the island is home to iconic ports. The Avatiu Harbour is a bustling hub where cruise ships dock, boat tours depart and fishing charters head out for deep-sea excursions. You'll also find a semi-submersible tour to a century-old shipwreck. Nearby Avarua Harbour offers a more relaxed scene. The inlet is home to a few restaurants that serve traditional seafood dishes with views of small fishing boats bringing in daily hauls.

Escape to Muri Beach

If you visit Rarotonga, you'll almost surely make it to Muri. With lagoon waters that are protected by a reef and picturesque coastal islets, Muri Beach is a base for the majority of the island's water activities. It's where you can hire a kayak or stand-up paddleboard, kite-surf and take a tour on a glass-bottom boat. Resorts that range from upscale to affordable offer beachfront infinity pools for spending idyllic seaside days. Stroll white-sand beaches that are backed by palm trees and swim in Muri's calm lagoon waters.
