what is the weather in hawaii in december

Hawaii in December offers a fantastic escape from the winter blues. But what can you expect weather-wise? This guide will break down the typical conditions across the islands, helping you plan your perfect Hawaiian getaway. Forget shoveling snow – let's dive into sunshine!

Hawaii's December Weather: Averages and Expectations

December falls squarely within Hawaii's dry season, bringing generally sunny skies and pleasant temperatures across the archipelago. However, microclimates mean conditions can vary significantly between islands and even within the same island.

Temperature Ranges

Expect average daily highs in the low 70s (°F) and lows in the mid-60s (°F) across most of the islands. Maui and the Big Island tend to be slightly warmer, while Kauai and parts of Oahu may experience slightly cooler temperatures, especially at higher elevations. Nights are generally comfortable, rarely dipping below 60°F.

Rainfall

Rainfall is generally low in December, making it an ideal time for outdoor activities. However, the islands’ mountainous terrain can lead to localized showers, particularly in the afternoon. The windward (east-facing) sides of the islands tend to receive more rain than the leeward (west-facing) sides.

Sunshine

December boasts abundant sunshine across all Hawaiian islands. You can anticipate plenty of opportunities for soaking up the rays on the beach or exploring the stunning landscapes. Be sure to pack sunscreen!

Island-Specific December Weather Details

While the overall pattern is similar, each island has its nuances:

Oahu

Oahu, home to Honolulu, experiences relatively consistent weather in December. Expect warm, sunny days with occasional afternoon showers, particularly in the mountains. The beaches enjoy plenty of sunshine.

Maui

Maui offers similar temperatures to Oahu but often sees less rainfall. The dry western side of the island, particularly Kaanapali and Wailea, basks in almost constant sunshine. The eastern side, however, can experience more rain.

Kauai

Kauai, known as the "Garden Isle," enjoys lush greenery even in December. While generally sunny, it's also more prone to showers than other islands, particularly on the windward (east) side.

Big Island (Hawaii)

The Big Island, the largest of the Hawaiian Islands, has diverse microclimates. The Kona coast (west) remains mostly dry, while the Hilo side (east) often experiences more rainfall. Temperatures can vary depending on elevation, with higher altitudes significantly cooler.

What to Pack for a December Trip to Hawaii

Given the generally warm and dry conditions, pack light clothing such as shorts, t-shirts, sundresses, and swimwear. However, don’t forget a light jacket or sweater for cooler evenings or higher elevations. Rain gear, like a light raincoat or umbrella, is always a good idea, especially if you plan on exploring the rainier areas of the islands. Sunscreen, sunglasses, and a hat are essential for protecting yourself from the strong Hawaiian sun.

Beyond the Basics: Water Temperatures & Activities

December's ocean water temperatures are generally pleasant for swimming and other water activities, typically ranging from the mid-70s (°F) to the low 80s (°F). However, some areas might be slightly cooler, especially at higher elevations or after periods of rain. If you plan to surf, check water temperature reports before your session. December also provides excellent conditions for hiking, whale watching (humpback whales migrate to Hawaii during this time!), and other outdoor adventures.
