What's the weather Like in Rarotonga in January


With temperatures just slightly lower than those in February and March, January is one of the warmest times of the year. Daily average temperatures in January range from a high of 28C (82F) to a low of 24C (75F), with an overall average of 26C (79F). These temperatures are somewhat lower than other South Pacific locales such as Tuvalu and the Solomon Islands. The average sea temperature in Rarotonga is 28C (82F), making the water quite comfortable for the popular swimming, snorkelling and scuba diving that's found in the tranquil lagoon encircling Rarotonga's shores.      

Sunshine Hours

You'll see the years lowest levels of sunshine in January with an average of 7 hours a day, contrasted by the highs of 12 daily hours in September and October. The rain clouds that hang over the centre of the island for much of the year are more pronounced in January.  


January falls in the middle of Rarotonga's wet season (from November to May), so prepare for some precipitation if you visit during this month. In close competition with February and March for the wettest month of the year, January has an average of 19 rainy days with an overall average rainfall of 190mm. However, you can almost always count on sunny skies in the mornings with cooling downpours in the afternoons that arrive suddenly and recede just as quickly.


Be prepared for some muggy weather in January, the most humid month on the island. While average temperatures don't vary greatly from month to month, fluctuations in humidity make them feel as if they do. The average relative humidity in January is 85%, with humidity of around 89% in the mornings and 77% in the evenings. In short, January can feel hot, though the heat is offset by cooling rains.

Sunrise and Sunset

In January, the duration of daylight is constantly decreasing. On January 1, the sun rises at 6:00 am and sets at 7:24 pm, creating 13:24 hours of daylight. On January 31, with the shortest daylight of the month, daybreak happens at 6:21 am and sundown takes place at 7:23 pm, with 13:02 hours of total daylight.

Wind Speed

You can expect moderate winds of 4 m/s in January, which is about the strength of the light breeze you'll experience for most of the year.

Extreme Weather

January falls in the middle of the South Pacific's cyclone season from November to April. However, the Cook Islands are less likely to get hit by the tropical cyclones that are more apt to strike locations such as Fiji and Papua New Guinea. Strong storms that do hit Rarotonga can bring winds of up to 55 m/s (124 mph) and cause massive flooding, but these instances are rare.

Things to do in Rarotonga in January

Paddling a kayak

Paddling a kayak is one of the most-popular ways to explore Rarotonga's famed tropical lagoon. Steeped in Polynesian tradition, outrigger canoes have graced these shores for centuries. Glide through the sheltered turquoise waters to explore uninhabited islets and find a secluded spot for snorkelling or a picnic. Hire a glass-bottom kayak to view the colourful marine life that teems beneath you on your nature escape. When the afternoon winds pick up, the lagoon is also great for sailing and kite surfing.

Punanga Nui Cultural Market

If you're up to explore the local scene on land, head over to the Punanga Nui Cultural Market. Vendors offer the freshest fare and most unique artisan works at the bustling waterfront hub. Delight in Polynesian classics such as ika mata (fish marinated in coconut and lime), steamed taro leaves or a poke bowl with banana and arrowroot. Enjoy live music as you browse an assortment of handcrafted art. To really live like a local, you might even consider getting a tattoo. The area's tribes have long practised the art and the Polynesian term "tatau" gives us the English word we use today. You can find skilled tattoo artists who continue the custom with elaborate traditional designs. Later, catch a rugby match. The sport is wildly popular on Rarotonga. 

Te Rua Manga

Known as "The Needle", the most-iconic mountain peak on the island is the pointy spire of Te Rua Manga. You can go on a hike that brings you close to the scenic summit and take some inspiring photos that are sure to impress on Instagram. The trek begins in open fields, progresses through dense jungle terrain and passes a gentle stream. While reaching the summit is a difficult ascension that's best left to experienced climbers, those who make the attempt are rewarded with magnificent views of the coast and jungle canopy.
