Hawaii is a great year-round destination, but the best weather is usually found in April, May, September and October. The winter months are wetter, and June to November is the hurricane season, although big storms are rare.
When is the best time to visit Hawaii?
- The best time to visit Hawaii when the weather is good: Hawaii has a warm climate all year round, with average maximum temperatures of 26 to 28 °C in winter and 29 to 31 °C in summer.The winter months tend to be wetter, while the hurricane season runs from June to November (but big storms are rare here). Surfing waves are bigger in winter, especially on the northern coasts of the islands. The most consistent weather is generally found in April, May, September and October.
- Best time to surf: The best time to surf in Hawaii depends on the surfer’s skill level.The largest waves tend to hit the northern shores of all the islands in winter, from November through March, especially in December and January, and particularly on the north coast of Oahu. This is the best time for professionals, experienced surfers and spectators. Beginning surfers will want to stay on the south sides of the islands during the winter or travel in the summer months.
- Best time to swim and snorkel: Swimming and snorkeling are possible year-round in Hawaii, but during the summer months (May to September) the water is warmer, the waves are smaller and the skies are sunnier, making conditions ideal for these water activities.Kauai has the least reliable snorkeling because it tends to rain the most year round, which reduces visibility on the water.
- Best time to walk: Some of the most incredible hiking in the world can be found in Hawaii, especially on Kauai.Summers can be very hot here, so be sure to pack plenty of water and sunscreen, and plan to start your hike early in the morning, when the air temperature is cooler.
- Best time for whale watching: whales come down from Alaska to Hawaii every year during the winter, from December to April.The whales can be seen from the coast on each island, but tend to concentrate between the western coast of Maui and the neighboring islands of Molokai and Lanai.
- Best time to see the volcano: Kilauea on the Big Island has been erupting non-stop since 1983, sometimes in dramatic bursts and sometimes in lazy flows.Temperatures at the highest elevations are about 6-11 degrees Celsius colder than at sea level, with winter temperatures averaging 8-12 degrees Celsius. Summer (May to September) is the best time to visit the volcano while it’s still warm.
- Best time to fish: Fishing is a year-round activity in Hawaii, with different fish biting at different times on different islands.(Except for sharks: you can always find sharks.) In general, in the winter you can see a lot of striped marlin, snapper, skipjack and bigeye; and there is also a good chance to see a whale while you are away. spring offers more mahi mahi, yellowfin and blue marlin. summer finds yellowfin and large blue marlin, along with ono and skipjack. autumn sees lots of billfish, all varieties of marlin, mahi mahi and giant jacks.
- The best time to watch the stars on Mauna Kea: similar rules apply to visiting Mauna Kea as to visiting Kilauea.For visibility, the best time of the month to see stars is during a new moon. If you plan to use the world-class telescopes on the summit of Mauna Kea, remember to consider the elevation; at almost 4,200 meters, Mauna Kea’s oxygen level is low.It is strongly recommended that travelers stop halfway for one hour to acclimate and never ascend Mauna Kea within 24 hours of diving.
- Best time to ski/snowboard: Mauna Kea means «white mountain» in the Hawaiian language.The best time to ski/snowboard Mauna Kea is during February and March. there are no lifts or resorts, and you’ll need a 4-wheel drive vehicle, but the snow is said to be among the best in the world.
- Best time to discount: for discounted rates, it’s usually best to book in advance and schedule flights for mid-week.In general, the cheapest airfares and hotels can be found during the spring and fall months. late March to mid-June is generally a great time to find great rates, except during the last week of April, which is Golden Week, Japan’s best time to travel. later in the year, from September to mid-December, is also a great time to find deals, except during Thanksgiving week.June and July are usually less expensive than the expensive winter months, but they are more crowded; offers during this time tend to be rare and last minute.
- The best time to avoid crowds: the quietest month for tourists is November, with the exception of Thanksgiving week.May to the first week of June, September and October are also good times to avoid crowds.April can be quiet, except during Golden Week and during the years when Easter falls at the beginning of the month.
- The best time for a wedding: the summer months tend to be drier than the winter months, so planning a wedding from May to October means less chance of rain, although Kauai and Hilo almost always have some rain.the hurricane season usually runs from June to November, but big storms are rare.The best bet for a sunny wedding is May.
- Best time for inter-island cruises: the winter months, December to March, are the best time to watch whales from the side of your boat, but this is also the rainiest and most expensive time to visit.
- Best time to buy flights: Flight prices fluctuate dramatically. In general, booking one to four months in advance offers the best rates, with six weeks being the optimal time to find deals. Exceptions are when booking for Thanksgiving week and mid to late December. For these times, it is generally best to book as soon as tickets are available, up to eleven months out.

Although the rainy and dry seasons fall during the same time for both regions, Hilo and Volcano experience almost twice as much rain as Kailua-Kona during the wet season.The best surfing hits the east and west coasts during the winter, although the waves are smaller here than on the other islands; the best surfing months are between December and February. The high season and whale season (Kohala Coast and Hilo Bay) runs from late December to March, while the low season is during April and May and September to mid-December.
