If you are dreaming of trading freezing temperatures, snow-covered roads, and heavy winter coats for warm beaches and tropical sunshine, Hawaii in the winter can be an incredible escape. But just how warm is Hawaii during the winter months?
The good news is that Hawaii in the winter temperature range remains pleasantly warm compared with most of the continental United States. At sea level, Hawaii's average daytime winter temperature is around 78°F (25.6°C), with nighttime temperatures generally about 10 degrees cooler.
Winter does bring some changes, however. Cooler evenings, increased rainfall, larger ocean swells, and significant differences between sunny coastal areas and higher elevations can all affect what visitors experience. Understanding Hawaii's winter weather can make it much easier to decide what to pack, where to stay, and which activities to plan.
Hawaii generally recognizes two primary seasons: summer (kau), from May through October, and winter (hoʻoilo), from November through April. Unlike destinations with four dramatically different seasons, Hawaii experiences relatively small temperature changes throughout the year.
According to Hawaii's official tourism website, average daytime temperatures at sea level are approximately 78°F during winter, compared with about 85°F during summer. Nighttime temperatures are typically around 10°F cooler.
For travelers visiting in December, January, or February, that generally means plenty of weather suitable for beaches, hiking, sightseeing, snorkeling, and other outdoor activities.
January and February are among the cooler months. Typical daytime highs across popular coastal destinations are often in the upper 70s to low 80s, while nighttime temperatures can fall into the 60s.
For perspective, Honolulu averages around 81°F for the daytime high and 67°F for the nighttime low in both January and February.
Along the coast, "cold" is relative.
A morning temperature in the upper 60s might feel chilly to a Hawaii resident, but visitors arriving from snowy climates may find it extremely comfortable. During the afternoon, sunshine can quickly make temperatures in the upper 70s or low 80s feel much warmer.
Elevation is where things change dramatically.
Hawaii contains numerous microclimates because of its mountains, trade winds, and volcanic geography. Visitors can encounter warm beaches, tropical rainforests, dry landscapes, and genuinely cold alpine conditions during the same vacation.
This is particularly important on Maui and Hawaii Island. Visiting the summit of HaleakalÄ on Maui or high-elevation areas around Mauna Kea on Hawaii Island is nothing like spending the afternoon on the beach.
Temperatures at high elevations can become extremely cold, especially overnight and around sunrise. Winter snow can even occur on Hawaii's highest volcanic summits.
So, while you probably won't need a winter jacket for Waikiki or Wailea, warm layers can be essential for high-elevation adventures.
Yes. Winter is generally considered Hawaii's wetter season.
However, that does not mean visitors should expect nonstop rain throughout their vacation. The National Weather Service notes that winter weather can become more unsettled as storm systems and cold fronts reach the islands. At the same time, normal trade-wind conditions still occur frequently, bringing sunshine mixed with relatively brief showers.
Where you stay also makes a major difference.
Hawaii's mountains create significant differences between windward and leeward areas. Windward areas generally receive more clouds and rainfall, while many leeward resort areas tend to be sunnier and drier.
For example, on Maui, conditions around Kapalua or HÄna can be very different from those around KÄ«hei and Wailea on the same day.
That variety is part of Hawaii's tropical climate. A rainy morning doesn't necessarily mean an entire day of activities needs to be canceled.
The Pacific Ocean surrounding Hawaii plays a major role in keeping the islands' temperatures relatively stable.
According to the National Weather Service, sea surface temperatures around Hawaii generally reach their annual low of approximately 73°F to 74°F in late February and March, compared with around 80°F near their early-fall peak.
For many visitors, the ocean is still comfortable enough for swimming, snorkeling, surfing, and other water activities during winter.
Ocean conditions, however, deserve just as much attention as ocean temperature.
Winter produces some of Hawaii's largest surf, particularly along exposed north-facing shores. Hawaii's official tourism website describes winter as the heart of the islands' surf season, with large and consistent swells attracting experienced surfers.
Always check local ocean conditions and posted warnings before entering the water.
Temperature is only one reason travelers choose Hawaii during winter.
December through the winter months combines warm tropical weather with several seasonal experiences that aren't available year-round. Most notably, winter falls within Hawaii's humpback whale season, making it an especially exciting time for visitors interested in whale watching.
Winter is also an excellent season for hiking, sightseeing, scenic drives, ziplining, cultural experiences, and exploring Hawaii's diverse landscapes without the hottest temperatures of the year.
Surfers have another reason to visit: winter brings powerful swells to Hawaii's famous north-facing surf breaks.
The trade-off is that winterâparticularly the holiday periodâis a popular travel season. Travelers may encounter higher demand for airfare, accommodations, rental cars, and popular activities.
Packing for a Hawaii winter vacation usually doesn't require an entirely different wardrobe from a summer trip.
Shorts, T-shirts, swimsuits, sandals, sun protection, and lightweight clothing will still be useful for most days. However, adding a light sweater, sweatshirt, or rain jacket is a smart idea for cooler mornings, evenings, rainy weather, and higher elevations.
If you're planning a HaleakalÄ sunrise or another high-elevation excursion, bring genuinely warm layers rather than relying solely on beach clothing.
It is also smart to pack based on your planned activities instead of looking only at Hawaii's average temperature. A traveler spending a week at a beachfront resort will have very different clothing needs from someone planning rainforest hikes and summit adventures.
For many travelers, absolutely.
Hawaii's winter temperatures provide an appealing balance: warm enough to enjoy the beach and ocean but generally cooler than the hottest months of the year. There may be more rain, particularly in windward areas, but sunny weather remains common.
The combination of roughly upper-70s to low-80s coastal daytime temperatures, warm ocean water, whale season, dramatic winter surf, lush scenery, and outdoor activities makes winter one of Hawaii's most distinctive seasons.
If your idea of winter involves escaping freezing temperatures without giving up outdoor adventures, Hawaii is difficult to beat.
For current forecasts and additional trip-planning information, these resources can help:
What is the average temperature in Hawaii in the winter?
At sea level, Hawaii's average daytime winter temperature is approximately 78°F (25.6°C). Nighttime temperatures are generally about 10°F cooler.
How cold does Hawaii get in December?
Coastal areas generally remain warm during December, with daytime temperatures commonly reaching the upper 70s or low 80s. For example, Honolulu's normal December high is around 82°F.
Is Hawaii warm enough to swim in the winter?
Yes. Many visitors swim, snorkel, surf, and participate in other ocean activities throughout winter. Sea surface temperatures around Hawaii reach their coolest levels around 73°F to 74°F in late February and March.
What is the coldest month in Hawaii?
February and March tend to be Hawaii's coolest period because the surrounding Pacific Ocean takes time to cool after summer.
Does Hawaii get snow during the winter?
Snow is possible at the highest elevations, particularly on Hawaii Island's tallest volcanic summits. Coastal resort areas do not experience snowy winter conditions.
Is Hawaii rainy during the winter?
Winter is Hawaii's wetter season, but rain varies considerably by island, elevation, and whether you are staying on the windward or leeward side. Rain does not necessarily last all day, and sunny periods are common even during winter.
Is December, January, or February better for visiting Hawaii?
All three can be excellent months. December offers holiday travel and warm weather, while January and February generally bring slightly cooler temperatures and remain excellent months for seasonal activities such as whale watching.
What clothes should I wear in Hawaii during winter?
Light summer clothing is appropriate for most coastal areas during the day. Bring a light jacket or sweatshirt for evenings, rain protection for changing weather, and significantly warmer clothing if visiting high-elevation locations such as HaleakalÄ.
Is Maui warm in the winter?
Yes. Maui's coastal resort areas remain pleasantly warm throughout winter. Conditions vary considerably around the island, however, because elevation and geography create distinct microclimates.
Is it better to visit Hawaii in winter or summer?
It depends on your priorities. Winter offers slightly cooler temperatures, whale watching, powerful surf, and lush landscapes, while summer typically brings warmer temperatures and generally more consistent dry-season conditions.

When people imagine Hawaii, they think of palm trees, warm trade winds, turquoise water, and lava-formed coastlines. Very few expect to see snow. Yet every winter, snow on Mauna Kea transforms the summit of Hawaiiâs tallest mountain into a surreal alpine landscape rising above tropical beaches. This rare and striking phenomenon is one of the most fascinating natural contrasts on Earthâand a powerful reminder of Hawaiiâs geographic and climatic extremes.
Located on the Big Island, Mauna Kea stands 13,803 feet above sea level, making it the highest point in the Hawaiian Islands. Because of its immense elevation, Mauna Kea regularly experiences winter conditions that rival mountain ranges on the mainland, despite sitting in the middle of the Pacific Ocean.
The reason snow on Mauna Kea occurs lies almost entirely in elevation and atmospheric physics. As air rises, it cools. Temperatures drop roughly 3.5°F for every 1,000 feet gained in altitude. While coastal Hawaii may sit comfortably in the 70s or 80s, the summit of Mauna Kea can dip well below freezing during winter storms.
Between December and March, cold fronts from the North Pacific occasionally reach the Big Island. When enough moisture and cold air coincide, precipitation falls as snow rather than rain at the summit. These snowstorms can blanket the upper slopes, turning a volcanic landscape into a snow-covered plateauâsometimes deep enough to temporarily close summit access roads.
Snowfall on Mauna Kea is not a daily or even weekly occurrence, but it is a consistent seasonal event. Most years see multiple snowfalls, ranging from light dustings to heavy storms. Some winters bring dramatic accumulations that linger for days or even weeks, depending on sun exposure and temperatures.
While snow is most common in mid-winter, it has been recorded as early as October and as late as May. The variability adds to the mystique of snow on Mauna Kea, making each event feel rare and special, even though it happens regularly by climatological standards.
For Native Hawaiians, Mauna Kea is not just a mountainâit is a sacred place, deeply tied to genealogy, cosmology, and spiritual practice. Snow, known in Hawaiian as hauÊ»oliÊ»oli or hau kea, appears in ancient chants and legends describing the summit as a realm of the gods.
Historically, snow from Mauna Kea was gathered and transported to aliÊ»i (chiefs) as a symbol of prestige and sacred power. The presence of snow reinforced the mountainâs status as a bridge between the heavens and the earth. Today, the appearance of snow continues to hold cultural meaning, reminding residents and visitors alike that Mauna Kea is a place deserving of reverence and respect.
Another reason snow on Mauna Kea captures global attention is the presence of world-class astronomical observatories at the summit. Mauna Keaâs high elevation, dry air, and minimal light pollution make it one of the best stargazing locations on Earth.
Snowfall occasionally interrupts operations, coating telescopes and access roads, but it also highlights the extreme environment in which these scientific instruments operate. Images of snow-covered observatories against a backdrop of blue Hawaiian sky often go viral, surprising viewers who never associated Hawaii with winter weather.
Witnessing snow on Mauna Kea can be unforgettable, but it requires careful planning and respect for safety. Winter conditions can make the summit hazardous, with icy roads, low visibility, and rapidly changing weather. Access to the summit is frequently restricted during snowstorms, and four-wheel drive vehicles are required even in clear conditions.
Many visitors choose to stop at the Mauna Kea Visitor Information Station, located at 9,200 feet, where snow is sometimes visible higher up without the risks of summit travel. Whether you reach the summit or not, seeing snow on Mauna Kea from below is still a remarkable experienceâespecially when the coastline remains warm and sunny.
What makes snow on Mauna Kea so captivating is the contrast it creates. Few places on Earth allow you to swim in the ocean, hike through lava fields, and see snow-covered peaks all in a single day. This striking diversity is part of what makes the Big Island unique, and Mauna Kea stands at the center of that experience.
The mountainâs snow serves as a reminder that Hawaii is far more than beachesâit is a land of extremes, shaped by volcanic forces, atmospheric dynamics, and deep cultural history.
Snow on Mauna Kea is one of Hawaiiâs most extraordinary natural phenomenaâa fleeting yet powerful example of how elevation, climate, and culture converge atop the tallest mountain in the islands.
Does it really snow on Mauna Kea every year?
Yes. Snow on Mauna Kea occurs almost every year during the winter months, although the amount and duration vary depending on weather patterns.
What months can you see snow on Mauna Kea?
Snow is most common from December through March, but it has been recorded as early as October and as late as May in colder years.
Is Mauna Kea the only place in Hawaii that gets snow?
Mauna Kea receives the most snow, but nearby Mauna Loa can also experience snowfall at high elevations during strong winter storms.
Can visitors drive to see snow on Mauna Kea?
Sometimes. Summit access may be closed during snow or icy conditions. Visitors should always check road conditions and heed safety warnings before attempting the drive.
How cold does it get when there is snow on Mauna Kea?
Temperatures at the summit can drop well below freezing, especially at night, creating icy and potentially dangerous conditions.
Why is snow on Mauna Kea so surprising?
Because Hawaii is associated with tropical climates, many people are unaware that its tallest mountains rise high enough to support snow and winter weather.
