Dreaming of a December escape to Hawaii? The Aloha State offers a tropical paradise, but understanding the weather nuances is key to planning the perfect trip. While Hawaii boasts consistently warm temperatures year-round, December brings its own unique weather characteristics. Let's explore what you can expect.

December's Average Temperatures:

Across the Hawaiian Islands, December delivers average highs ranging from the mid-70s°F (low 20s°C) to the low 80s°F (high 20s°C). The average lows generally hover in the 60s°F (mid-teens°C). This means pleasant daytime temperatures perfect for outdoor activities, and comfortable evenings that might require a light jacket, especially at higher elevations.

Rainfall:

Rainfall in Hawaii varies significantly by island and location. December falls within Hawaii's wetter season, particularly on the windward (eastern) sides of the islands. However, this doesn't mean constant downpours. Instead, expect short bursts of rain interspersed with sunny periods. The leeward (western) sides usually experience drier conditions.

• Example: Maui, for instance, often sees more rainfall on its eastern slopes (Hana) compared to its western (Kaanapali) coast during December. This is due to the prevailing trade winds pushing moisture up the mountains.

Ocean Temperatures:

Ocean temperatures remain comfortably warm in December, generally ranging from the mid-70s°F (low 20s°C) to the low 80s°F (high 20s°C). This makes swimming, snorkeling, and other water activities enjoyable.

Specific Island Considerations:

While the general trends are similar, each Hawaiian island possesses its own microclimates.

• Kauai: Expect lush greenery and potential for heavier rainfall, especially in the north.
• Oahu: Offers a diverse range of weather, from sunny beaches to rainier mountain areas.
• Maui: Presents a contrast between drier west and wetter east sides.
• Big Island: Due to its size and varied elevations, the Big Island experiences diverse weather patterns, from sunny beaches to snow atop Mauna Kea (though snow is less likely in December).

Additional Factors:

• Altitude: Higher elevations, like those found on Haleakala (Maui) or Mauna Kea (Big Island), experience significantly cooler temperatures.
• Trade Winds: The consistent trade winds can bring refreshing breezes, but they also influence rainfall patterns.
• Microclimates: Even within a single island, you can encounter vastly different weather conditions depending on location and elevation.

Packing Recommendations:

Pack light clothing suitable for warm weather, but also include a light jacket or sweater for cooler evenings or higher elevations. Don't forget swimwear, sunscreen, a hat, and rain gear.

In Conclusion:

December in Hawaii offers a wonderful escape from colder climates. While rainfall is more likely than during the drier months, the overall weather remains pleasant and conducive to a wide variety of activities. By understanding the nuances of each island's weather patterns and packing accordingly, you can ensure a memorable and enjoyable Hawaiian holiday. Remember to check specific weather forecasts closer to your travel dates for the most accurate information. Enjoy your trip!
