Hey guys! Planning a trip to Hawaii in December and wondering what the weather will be like? You've come to the right place! Let's dive into the details of Hawaii's December weather, including temperatures, what to expect, and how to pack, all while keeping it super casual and helpful.

Overview of Hawaii Weather in December

December in Hawaii is a sweet spot for many travelers. The islands are lush and vibrant, having transitioned from the drier summer months. You'll find that the weather is generally pleasant, with a mix of sunshine and occasional rain. The temperatures are mild, making it perfect for escaping colder climates. But what exactly does that mean in terms of degrees? Let’s break it down.

General Temperature Ranges

In December, you can typically expect daytime temperatures in Hawaii to range from the mid-70s to low 80s Fahrenheit (around 24-28 degrees Celsius). Evenings can be a bit cooler, dropping to the mid-60s to low 70s Fahrenheit (18-23 degrees Celsius). Of course, this can vary slightly depending on which island you visit.

Island-Specific Temperatures

  • Oahu: Expect daytime highs around 80°F (27°C) and nighttime lows around 68°F (20°C). Oahu tends to be a bit drier in December compared to some of the other islands.
  • Maui: Similar to Oahu, Maui sees daytime highs around 80°F (27°C) and nighttime lows around 68°F (20°C). West Maui might be slightly warmer and drier than East Maui.
  • Kauai: Known as the "Garden Isle," Kauai tends to be a bit wetter in December. Daytime highs hover around 78°F (26°C), and nighttime lows around 66°F (19°C).
  • Big Island (Hawaii Island): The Big Island is unique because its diverse geography leads to varied weather conditions. Coastal areas like Kona and Hilo will have daytime highs around 80°F (27°C), while higher elevations like Volcanoes National Park will be significantly cooler, sometimes dropping into the 50s Fahrenheit (10-15 degrees Celsius).

Ocean Temperatures

The ocean around Hawaii in December is usually around 75°F (24°C), which is perfect for swimming, snorkeling, and other water activities. No need for a wetsuit unless you plan on spending extended periods in the water or are particularly sensitive to cooler temperatures.

Rainfall Expectations

December falls within Hawaii's wet season, so expect some rain. However, it’s usually not constant downpours. Instead, you’ll likely experience short, tropical showers, often followed by sunshine. These showers are more frequent on the windward (east and north) sides of the islands. For example, Hilo on the Big Island is known for its rain, while Kona, on the leeward side, tends to be drier. Kauai, being the northernmost island, generally sees more rainfall in December than the others. Bottom line: pack a light rain jacket, but don’t let the thought of rain deter you. It’s part of what keeps Hawaii so green and beautiful!

What to Expect in Terms of Weather Conditions

Okay, now that we've covered the temperatures, let's chat about what else you can expect weather-wise in Hawaii during December. This includes sunshine, humidity, and the possibility of storms.

Sunshine and Cloud Cover

Even though December is part of the wet season, you'll still get plenty of sunshine. Typically, you can expect several hours of sunshine each day, especially on the leeward (west and south) coasts of the islands. Cloud cover can vary, but it's generally a mix of sunny skies and scattered clouds. Mornings often start clear, with clouds building up in the afternoon, sometimes leading to those brief showers we talked about. Don't forget your sunscreen, even on cloudy days – the Hawaiian sun is strong!

Humidity Levels

Hawaii is a tropical paradise, which means humidity is part of the deal. In December, humidity levels are generally high, often ranging from 60% to 80%. This can make it feel warmer than the actual temperature, so dress accordingly. Lightweight, breathable clothing is your best friend. Staying hydrated is also super important, so keep that water bottle handy.

Potential for Storms

While Hawaii doesn't typically experience hurricanes in December, tropical storms can occur. These are relatively rare, but it's always a good idea to stay informed. Keep an eye on the local weather forecasts and heed any warnings issued by authorities. Generally, even if a storm passes through, it doesn't last long, and the islands quickly return to their beautiful, sunny selves.

Microclimates

One of the coolest things about Hawaii is its microclimates. Each island (and even different parts of the same island) can have vastly different weather conditions. For example, you might be basking in sunshine on one side of Maui while it's raining on the other. The Big Island is especially diverse, with everything from tropical rainforests to arid deserts and even snow-capped mountains in winter. Take advantage of this diversity by exploring different regions – just be prepared for varying weather conditions.

Activities to Enjoy in Hawaii in December

Despite the chance of rain, December is still an awesome time to visit Hawaii. The weather is mild, the crowds are smaller than during the peak summer months, and there's plenty to see and do. Here are some activities you might enjoy:

Water Activities

The ocean is warm and inviting in December, making it perfect for all sorts of water activities. Snorkeling and scuba diving are popular, with clear visibility and abundant marine life. Surfing is also great, especially on the North Shores of islands like Oahu and Kauai, where the winter swells bring bigger waves. Paddleboarding and kayaking are other fun options, and you can even take a whale watching tour (humpback whales start arriving in Hawaii in November).

Hiking and Outdoor Adventures

Hawaii's lush landscapes are ideal for hiking and outdoor adventures. Explore trails in Volcanoes National Park on the Big Island, hike to waterfalls in Kauai's Na Pali Coast, or wander through the bamboo forests on Maui. Just be sure to wear appropriate footwear and check the weather forecast before you head out. A light rain jacket can also come in handy.

Cultural Events and Festivals

December is a festive time in Hawaii, with various cultural events and festivals taking place. Check out local Christmas celebrations, attend a Polynesian cultural show, or visit a farmers market to sample local produce. The Honolulu City Lights is a popular event on Oahu, featuring a dazzling display of Christmas decorations and lights.

Relaxing on the Beach

Of course, no trip to Hawaii is complete without spending some time relaxing on the beach. Even in December, you'll find plenty of sunny days perfect for lounging on the sand, swimming in the ocean, and soaking up the Hawaiian vibes. Some of the best beaches include Waikiki Beach on Oahu, Kaanapali Beach on Maui, and Poipu Beach on Kauai.
