What's the weather like in Hawaii in January

January offers the coldest weather of the year across the Polynesian islands of Hawaii. But that doesn't mean the climate is ever chilly.


In fact, average temperatures are still a very warm 23°C at this time of the year, with the warmest part of the day usually reaching a peak of up to 26°C.

As January is part of the wet season in this part of the United States of America, there are many days when there will be some rain. However, it is by no means the wettest month of the year, which is usually November. Instead there will be an average of 78mm of precipitation spread over approximately 18 days.


The most significant rainfall is always likely to fall in the north and the east of the Islands, which means that, even when it is raining in the north of the Island, the south can still be very dry. And even if the weather in your area is wet, most of the rain will occur at night and any daytime rain is likely to be no more than a short lived shower.

Sea Temperature

Thanks to the cooler air temperatures and the rain over November and December, sea temperatures in January are likely to be slightly cooler than they are in the warmest parts of the year. And though the average temperature is still a very welcoming 25°C in January, this slightly cooler turn ensures there are plenty of big swells and tubes for the most avid surfers.

Sunshine Hours

At night time, temperatures will drop, usually to an average low of approximately 20°C, which ensures anyone trying to get away from the cold weather back home will be more than satisfied. And with an average of eight hours of daily sunshine across the archipelago, Hawaii in January is a wonderful place to be.

Set directly on the beach, even if the waves are too rough, the onsite pool provides the perfect place to cool down and relax. And though it is not the most economical place to stay on the island, for those that have the budget, this is a treat that shouldn't be missed.

Honu Kai B&B

Situated on the main island of Hawaii, the Honu Kai B&B offers an alternative type of accommodation on the islands. Located just a few minutes' walk from the lively town of Kailua Kona, this family run accommodation makes everyone feel at home. The house itself offers four beautifully maintained bedrooms, all with their own private facilities. And from every room there is a breath-taking view over the lush tropical rainforest.

Bars and Restaurants

Keoki's Paradise

For anyone staying or visiting Kauai, Keoki's Paradise is the spot for a great night out. Though the venue is actually part of the shopping plaza, the tropical atmosphere paves the way for a beautiful open air setting. Choose from the fully seated restaurant area for a full meal or the funky bar to enjoy the nightlife. A wide selection of dishes usually includes a choice of up to four different types of fresh fish, all of which are cooked to perfection. And even though booking is essential in January, prices are still very reasonable. Make sure you leave room for the Hula Pie at the end of the meal. No one should leave Keoki's without it.

Mai Tai Bar

For locals on the main island of Hawaii, the Mai Tai Bar at the Royal Hawaiian Hotel is considered the birthplace of the Mai Tai, so it would be a shame not to go and try this delicious drink at its best. Situated next to the beautiful sands of Waikiki Beach, this is a wonderful place to sit and unwind after a 'hard day' sightseeing. Relax and listen to the live local music performed every night of the week and soak in the elegant atmosphere. Heads of state, international celebrities and some of the world's wealthiest people frequent the Mai Tai Bar, so you never know who you might meet.

Mama's Fish House

On Maui, there's nowhere better to get a true taste of Hawaii than at Mama's Fish House. Famous for serving the freshest food with the best flavours, prices do reflect the popularity of the restaurant, but they are always worth paying. The service is impeccable and the waiters are always on hand to make their recommendations. They will even provide guidance on the best drinks to go with the meal. And though booking is always recommended, if you arrive early enough there should always be somewhere to sit. To accompany the most perfect fine dining experience, Mama's offers a breath-taking view over the ocean. This ensures everyone that comes to Mama's Fish House, definitely wants to come back.

Things to do in Hawaii in January

USS Arizona Memorial

No one should visit Hawaii without a trip to the USS Arizona Memorial. As one of the most popular tourist spots in the region, the memorial is free to visit and provides a truly emotional insight into the Pearl Harbour attack. Boats run regularly to take all visitors to the island. And after a short introduction there is a 20 minute video that provides all the most important information on the site before the visit takes place. Often there is the opportunity to meet individuals who survived the attack and gain a first-hand account of everything that happened. Just make sure you take a second to absorb the atmosphere in this incredible location to truly appreciate all that happened there.

Summit of Mauna Kea

For a trip that is truly breath-taking book an excursion to the summit of Mauna Kea on the island of Hawaii. Visitors are taken from their chosen pick up points to a dining location at the Mauna Kea visitors centre before taking the final trip up to the top. See the observatories at the summit of this dormant volcano that are taking in all that changes in the night sky, before watching the sun set from the perfect vantage point. The guides are fully rehearsed in the history and detail of the area, to ensure everyone makes the most from their trip. In January, there may even be a little snow right at the top. It's a fabulous way to spend time.
