When is the Best Time to Visit Hawaii?
Hawaii is a great year-round destination, but the best weather is usually found in April, May, September, and October. Winter months are rainier, and June through November is hurricane season – though big storms are rare. Winter also brings the islands’ largest surf swells, especially on north shore beaches. The quietest month for tourists is November.
- Best Time to Visit Hawaii for Good Weather: Hawaii has warm weather all year round, with average highs of 26-28ºC in the winter, and 29-31ºC in the summer. The biggest variables are rain and surf conditions. Winter months tend to be rainier, while hurricane season goes from June through November (but big storms are rare here). Surf swells are largest in winter, especially on the islands’ north shores. The most consistently good weather is usually found in April, May, September, and October.
- Best Time to Book Hotels for Hawaii: The Best Hotels in Hawaii and the Best Hotels for Families in Hawaii get booked early – especially for July, August, late December, and early January. Try to reserve rooms at least three months in advance.
- Best Time for Surfing: The best time for surfing in Hawaii depends on the skill level of the surfer. The biggest waves tend to hit the north shores of all islands in winter, from about November through March – especially in December and January, and particularly on Oahu’s North Shore. This is the best time for pros, experienced surfers, and spectators. Beginning surfers will want to stick to the south sides of the islands during winter, or travel in the summer months. Waves are especially calm from May through September.
- Best Time for Snorkeling and Swimming: Great swimming and snorkeling are possible year-round in Hawaii, but during summer months (May through September) water is warmer, waves are smaller, and skies are sunnier, making conditions ideal for these water-based activities. Big Island and Maui tend to have the best snorkeling because their snorkel spots are affected less by trade winds from the east. Kauai has the least reliable snorkeling because it tends to rain more year-round, reducing visibility in the water.
- Best Time for Hiking: Some of the world’s most amazing hikes are found in Hawaii, especially on Kauai. Though hiking can be done year round, summer is usually best, because there are more daylight hours and the trails tend to be drier. Summers can get very hot here, so be sure to pack plenty of water and sunscreen, and plan on beginning your hike early in the morning, when the air temperature is cooler.
- Best Time for Whale Watching: Whales head down from Alaska to Hawaii every year for the winter, from December through April. The peak time for sightings runs from late February through early March, after the calves are born. Whales can be spotted from the coast on every island, but tend to concentrate between Maui’s western shores 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. There is no certain time of year that sees more or less lava than any other. The main factor in choosing when to visit is the weather. Temperatures at higher elevations are about 6-11 Celsius degrees cooler than at sea level with winter temperatures averaging 8-12ºC. Summer (May through September) is the best time for visiting the volcano while staying warm.
- Best Time for Fishing: Fishing is a year-round activity in Hawaii, with different fish biting at different times off different islands. (Except sharks – you can always find sharks.) Generally, winter sees lots of striped marlin, snapper, skipjack, and bigeye tuna; and there’s a good chance of spotting a whale while you’re out, too. Spring offers more Mahi mahi, yellowfin, and blue marlin. Summer finds jumbo-sized yellowfin and blue marlin, along with ono and skipjack. Fall sees lots of billfish, all varieties of marlin, mahi mahi, and giant trevally.
- Best Time for Stargazing on Mauna Kea: Similar rules apply for visiting Mauna Kea as to visiting Kilauea. Colder winter temperatures mean that summer months are best for keeping warm. For visibility, the best time of month to see stars is during a new moon. If you plan to utilize the world-class telescopes on Mauna Kea’s summit, remember to keep elevation in mind; at nearly 4200 meters up, Mauna Kea’s oxygen level is low. It is highly recommended that travelers pause halfway up for an hour to acclimate and that they never ascend Mauna Kea within 24 hours of scuba diving.
- Best Time for Skiing/Snowboarding: Mauna Kea means “white mountain” in the Hawaiian language. There is snow here year-round, though its consistency varies. The best time for skiing or snowboarding 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 worldwide.
- Best Time for Discounts: For discounted rates, it’s usually best to book early and schedule flights for mid-week. In general, the cheapest rates on flights and hotels can be found during the spring and fall months. Late March through mid-June usually finds great rates, except during the last week in April, which is Golden Week, Japan’s peak travel time. Later in the year from September through mid-December is also a fantastic time to find deals, except during the week of Thanksgiving. June and July are usually less expensive than the pricey winter months, but are more crowded; deals during this time tend to be both rare and last minute.
- Best Time for Avoiding Crowds: The quietest month for tourists is November, with the exception of Thanksgiving week. May through the first week of June, September, and October are also great times to avoid crowds. April can be quiet, except during Golden Week and during the years that Easter falls at the beginning of the month.
- Best Time for a Destination Wedding: Summer months tend to be drier than winter months, so planning a wedding for May through October means less chance of rain, though Kauai and Hilo nearly always have some rain. Hurricane season generally goes from June through November, but big storms are rare. The best bet for a sunny wedding is May.
- Best Time for Inter-Island Cruises: Winter months, December through March, are the best times to spot whales off the sides of your ship, but this is also the rainiest and most expensive time to visit. The best time for cruise deals is between Thanksgiving and mid-December. A greater variety of boats can be found in April, September, and October.
- Best Time for Buying Airline Tickets: Prices for flights fluctuate dramatically. Generally, booking one to four months in advance offers the best rates, with six weeks out being the optimal time for finding deals. Exceptions are when booking for Thanksgiving week and mid to late December. For these times, it’s usually best to book as soon as tickets are available, up to eleven months out.
When To Visit The Hawaiian Islands
The Best Time to Visit Oahu
The best months to visit Oahu are April (the first 3 weeks), May, September, and October for great weather, fewer crowds, and fair rates. Oahu’s temperatures range from 26°C to 31°C all year long, with hot summers (June through October) and pleasant winters (mid-December through late March). There is not much weather variation in the lower altitudes where all beaches and most hotels are; higher elevations inland are cooler and rainier. Rain typically falls overnight. December through February is the rainiest time of year, while June through August is the driest. Early August through early November sees the warmest ocean temperatures, and mid-January through mid-April has the coldest. November through March sees monster waves hitting the north shore, attracting the huge surfing tournaments. The best time for surfers is from March through May, when the waves are still large, but the beach is less crowded. High season coincides with whale season (off the southern coast) from December through March, with high room and flight rates. Low season runs from April through mid-June (except the last week in April, which is Golden Week in Japan and brings large crowds to Honolulu) and September through early December with better rates and fewer travelers.
The Best Time to Visit Maui
The best months to visit Maui are April, May, September, and October. Maui’s daily highs range from the 27°C to 31°C year round, warmer in summer and cooler in winter, but only slightly. The west coast is generally warm, sunny, and dry, while the eastern Maui rainforest is slightly cooler with light rainfall in the late afternoons or overnight. Early June through late October is the driest time of year. November through March sees increased chances of light, brief showers. August through October sees the warmest ocean temperatures, while January through March has the coldest. The biggest surf hits the northern shore from mid-November through early February. December through March is both high season and whale-watching season (whales usually stick to the west coast), with the biggest crowds and the highest room rates. The low season falls from April through mid-June and September through mid-December, with fewer crowds and better rates.
Best Time to Visit Kauai
The best months to visit Kauai are April, May, August, and September for the best weather, lower rates, and smaller crowds. Kauai is the rainiest of the main Hawaiian Islands overall, but its microclimates differ drastically. The northern and eastern beaches (Princeville to Lihue) see regular rains, while the southern beaches near Po’ipu tend to be sunnier, and the western side all around Waimea Canyon is a desert. Mt. Waialeale, near the center of the island, is among the rainiest places on earth. Overall, year-round highs average from 27°C to 29°C, hottest from July through October and coolest from December through March. Brief rains are likely throughout the year, though late May to late September is the driest. Early August through late October sees the warmest ocean temperatures, while mid-January to mid-April is the coldest. November through February sees the largest waves on the north shore. High season and whale season (all around the island) run from mid-December through March; low season runs from April through early June and from September through early December.
Best Time to Visit the Big Island
The best months to visit the Big Island are mid to late-April, May, September, and October for the best combination of great weather, cheaper rates, and fewer people. The Big Island is huge, twice the size of all the other islands put together, with 8 entirely different climate zones. Most travelers only need to worry about 2 areas: Kailua-Kona in the west (hot, muggy, dry) and Hilo and Volcano in the east (warm, muggy, wet – Hilo is the wettest U.S. city). Temperatures are fairly constant throughout the year, with highs in between 27°C to 31°C in Kailua-Kona and highs between 26°C to 28°C in Hilo and Volcano. March and April are the rainiest months in both regions, while mid-May to late July are the driest. Though rainy and dry seasons fall during the same time for both regions, Hilo and Volcano experience almost double the rain of Kailua-Kona during the wet season. Ocean temperatures for both regions are almost exactly the same as one another; August through October is the warmest, while February and March are the coolest. The best surf hits the east and west shores during the winter, though waves are smaller here than on the other islands; the best surfing months are between December and February. High season and whale season (Kohala Coast and Hilo Bay) run from late December through March, while the low season is during April and May and from September through mid-December.
Hawaii Travel Seasons
- High Season (December – March): December through March is Hawaii’s high season, especially around the Christmas and New Year holidays. Flights, hotels, and cars will be at their most expensive this time. Hotels often require longer minimum stays, greater deposits, and have stricter cancellation policies around the holidays. Rental cars can sell out well in advance. Plan well and book early for peak season travel.
- Low Season (April through mid-June, September through mid-December): Spring and fall are the low seasons for travel in Hawaii, from April through mid-June (except the last week in April), and from September through mid-December (except for Thanksgiving week). Flights, hotels, and cars are less expensive, while beaches and attractions are less crowded.
- Summer (Mid-June through August): From mid-June through the end of August, family travel season is in full swing in Hawaii. Prices tend to be less expensive than during the winter months, but beaches and attractions will be more crowded. Fewer deals are available during the summer, especially in August, and the rare ones tend to be last minute.
Hawaii Weather by Month
Temperatures in Hawaii are warm all year long. Rain is more common in the winter months of November through March, with the rare big storm seen during the June to November hurricane season. Brief and light showers occur regularly everywhere. Kauai and the Hilo side of Big Island are the wettest areas, while West Maui and Big Island’s Kona coast are the hottest and driest. Surf is bigger and rougher in the winter, especially on the islands’ northern shores.
- Hawaii Weather in January: January is one of the cooler months of the Hawaiian year, with temperatures as low as 20ºC. Rain is likely, but not heavy. The north shores will see their most enormous waves during this month, with large swells in the west, too. It’s a good idea to bring a light jacket or dress in layers for evenings or for visiting high elevations. (Average high 26ºC, average rainfall 78mm, Honolulu average water temperature 24.7ºC.)
- Hawaii Weather in February: Average temperatures in February are the same as January, around 20-26ºC, but rain is a little heavier. Huge wages continue to hit the north and western shores. A light jacket and clothes that dry quickly are advised this time of year; whale watching excursions sometimes get splashy. (Average highs 26ºC, average rainfall 90mm, Honolulu average water temperature 24.4ºC.)
- Hawaii Weather in March: March temperatures remain the same as in February, with just a little less rain. Northern swells are still quite large but not the monsters of winter. Western waves may be a little bigger than those up north. (Average highs 26ºC, average rainfall 88mm, Honolulu average water temperature 24ºC.)
- Hawaii Weather in April: Temperatures hold steady from March to April, but rain drops off significantly. Layers are still a good idea, but rain gear can be left behind. Waves on all coasts in April range from flat to medium in size, and the water’s starting to warm up. Great time for snorkeling. (Average highs 26ºC, average rainfall 52mm, Honolulu average water temperature 25ºC.)
- Hawaii Weather in May: May is one of the sunnier and drier months of the year, and temperatures continue to heat up. Surf is still small to medium in most places, with warm ocean temperatures. This is considered one of the best months to visit Hawaii for outstanding weather conditions. (Average highs 27º, average rainfall 38mm, Honolulu average water temperature 25.5ºC.)
- Hawaii Weather in June: Gorgeous, sunny, and dry. June sees surf picking up on the south shores, while north shore waves disappear entirely. Ocean temperatures are incredibly comfortable beginning this time of year. (Average highs 28ºC, average rainfall 43mm, Honolulu average water temperature 26ºC.)
- Hawaii Weather in July: High temperatures hold steady in July, with a little more rain than in June. South swells reach their peak, bringing in some big waves. A jacket is still useful this time of year if visiting Haleakala Crater or taking a helicopter tour. (Average highs 28ºC, average rainfall 57mm, Honolulu average water temperature 26ºC.)
- Hawaii Weather in August: In August temperatures reach their upper limits, and rainfall is at its yearly low. Northern surf is still flat, while southern swells are large, and west and east waves are picking up in size. (Average temperature 29ºC, average rainfall 34mm, Honolulu average water temperature 26.5ºC.)
- Hawaii Weather in September: September has the warmest water temperatures of the year in Hawaii, while waves are medium to large on all shores. Air temperatures hold hot and steady. This is one of the rainier summer months, though there’s still not as much rain as is seen in the winter. (Average temperature 29ºC, average rainfall 61mm, Honolulu average water temperature 27ºC.)
- Hawaii Weather in October: October is the last really warm month here, though the rains are beginning to pick up. Waves on the south and east begin to subside, and the north and western swells begin to ramp up for winter. A rain jacket or umbrella may be useful if visiting during this time of year. (Average temperature 29ºC, average rainfall 80mm, Honolulu average water temperature 26.5ºC.)
- Hawaii Weather in November: This is the rainiest month in Hawaii by far, seeing three times as much precipitation as in May or August. Bring an umbrella, and plan some rainy day activities in case of a downpour. Water and air temperatures are still very comfortable, and north and western waves are large again, to the delight of many a surfer. (Average temperature 27º, average rainfall 124mm, Honolulu average water temperature 26ºC.)
- Hawaii Weather in December: In December, air temperatures reach their winter lows, which generally hold steady throughout the coming months. Water temps are still comfortable, though not quite balmy. Southern waves flatten out entirely, while western and especially northern surf grows bigger. The first whales of the season should be showing up now. (Average temperature 26ºC, average rainfall 87mm, Honolulu average water temperature 25ºC.)
