    Hawaii Weather for January 2021

    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.

    Things to do in Hawaii in January

    USS Arizona Memorial

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.
