December in Hawaii, guys, is like hitting the jackpot! You're escaping the frosty clutches of winter for a tropical paradise. But what exactly does the weather in Hawaii look like in December? Let's break it down, so you know exactly what to pack and what kind of sunshine-filled adventures await you.

Overview of Hawaii's December Climate

So, you're dreaming of a Hawaiian Christmas? Smart move! December is technically part of Hawaii's wet season, but don't let that scare you off. The rainfall is usually pretty manageable, and you'll still see plenty of glorious sunshine. Think of it as a refreshing break from the warmth. The temperatures are comfortably warm, not scorching hot, making it perfect for exploring the islands, hitting the beaches, and enjoying outdoor activities without melting into a puddle. This is the sweet spot, my friends!

Temperature Averages

Let's get down to the nitty-gritty: temperatures. In December, you can expect average daytime temperatures to hover around the mid-70s to low 80s Fahrenheit (that's about 24-28 degrees Celsius for our international friends). Evenings cool down a bit, usually dropping to the mid-60s to low 70s Fahrenheit (around 18-23 degrees Celsius). This means you can leave your heavy winter coats at home, but packing a light jacket or sweater for the evenings is a smart idea. You'll be thanking yourself when you're sipping cocktails under the stars!

Rainfall Expectations

Okay, let's talk about rain. December does see an increase in rainfall compared to the summer months. However, it's not like you'll be stuck indoors your entire vacation. The rain tends to come in short bursts, often in the late afternoon or evening. Plus, different islands and even different sides of the same island can experience vastly different rainfall amounts. The windward (eastern) sides of the islands generally get more rain than the leeward (western) sides. So, if you're really concerned about rain, consider staying on the leeward side. Don't forget to pack a light rain jacket or umbrella, just in case. Being prepared is always a good move!

Ocean Conditions

For all you water lovers out there, the ocean in December is still very inviting. The water temperature usually stays around 75 degrees Fahrenheit (24 degrees Celsius), which is perfect for swimming, snorkeling, and surfing. However, December is also the start of the North Shore's big wave season. So, if you're planning on surfing, be sure to check the conditions and stick to beaches that are appropriate for your skill level. And always, always respect the ocean!

Island-by-Island Breakdown

Because each island has its own unique microclimate, let's take a quick look at what you can expect on some of the major Hawaiian islands in December.

Oahu

Oahu is a popular choice, and for good reason! In December, you can expect average high temperatures in the low 80s Fahrenheit and lows in the mid-60s. Rainfall is moderate, with the windward side (Koolau mountains) seeing more rain than the leeward side (Waikiki). The North Shore is where the big wave surfing action is at, so be cautious if you're not an experienced surfer. Waikiki offers calmer waters that are perfect for swimming and other water activities.

Maui

Maui, the "Valley Isle," boasts similar temperatures to Oahu in December. Expect average highs in the low 80s Fahrenheit and lows in the upper 60s. Rainfall is also moderate, but the western side of the island (like Kaanapali and Lahaina) tends to be drier than the eastern side (like Hana). The Road to Hana can be particularly rainy, so be prepared if you're planning a drive. The south and west coasts usually offer calmer ocean conditions for swimming and snorkeling.

Kauai

Kauai, the "Garden Isle," is known for its lush greenery, which means it gets its fair share of rain. December is one of the wetter months on Kauai, especially on the North Shore (around Princeville and Hanalei). However, even with the rain, Kauai is still incredibly beautiful. The South Shore (Poipu) tends to be drier and sunnier. Temperatures are similar to the other islands, with average highs in the low 80s Fahrenheit and lows in the mid-60s. Be sure to check the weather forecast before heading out on any hikes, as trails can become slippery after rain.

Big Island (Hawaii Island)

The Big Island is the most diverse in terms of climate. Because of its size and varying elevations, you can experience everything from tropical rainforests to volcanic deserts. In December, the Kona side (west) is generally sunny and dry, while the Hilo side (east) is wetter. Temperatures range from the low 80s Fahrenheit on the coast to much cooler temperatures at higher elevations, like Volcanoes National Park. If you're planning on visiting the summit of Mauna Kea, be prepared for freezing temperatures and even snow!

Activities to Enjoy in December

Despite being the wet season, December in Hawaii offers a plethora of activities to enjoy.

  • Whale Watching: December marks the beginning of whale watching season in Hawaii. Humpback whales migrate from Alaska to breed and give birth in the warm Hawaiian waters. You can take a whale watching tour from any of the major islands.
  • Surfing: As mentioned earlier, December is prime time for big wave surfing on the North Shore of Oahu. If you're not a pro, you can still enjoy surfing at more beginner-friendly beaches.
  • Hiking: Hawaii offers incredible hiking trails, ranging from easy coastal walks to challenging mountain treks. Just be sure to check the weather forecast and be prepared for rain.
  • Snorkeling and Diving: The ocean is still warm and inviting in December, making it a great time for snorkeling and diving. You can explore vibrant coral reefs and encounter a variety of marine life.
  • Cultural Events: December is a festive time in Hawaii, with various cultural events and celebrations taking place. Check out local events calendars for festivals, parades, and holiday celebrations.
  • Relaxing on the Beach: Of course, you can't go to Hawaii without spending some time relaxing on the beach! Even with the occasional rain shower, there will be plenty of sunny days to soak up the rays.
