While Hawaii never experiences harsh winter cold, December brings moderate trade winds, slightly higher rainfall on some shores, and comfortable temperatures that still suit sun-filled days. The following sections break down what to expect, how to plan, and how prices and conditions compare during this popular visiting period.

December Temperature Comfort Across the Islands
December temperatures in Hawaii remain mild to warm, with daytime highs hovering in the upper 70s to low 80s Fahrenheit. Nighttime lows rarely drop below 68°F, which means light layers or a thin top are usually enough for evening outings.
Trade winds provide a cooling effect, especially on exposed coasts, while sheltered bays and inland valleys feel warmer. These conditions make sightseeing, hiking, and city walks comfortable without the intense summer heat.
Compared to the busy November period, December sees slightly more variable weather as Pacific storm systems approach. Yet most days still offer plenty of sunshine, and sudden rain showers tend to pass quickly rather than lingering all day.
Rainfall Patterns and Which Coasts Stay Drier
Rainfall in December is moderate and region-specific, with windward coasts receiving more showers than leeward sides. North and east facing slopes see greener landscapes, while south and west shores usually stay sunnier and drier.
On Oahu, the Waianae Coast is notably drier, while the windward north shore may experience brief showers. Maui’s leeward southwestern areas, including resort zones around Wailea, often enjoy clearer skies compared to Hana’s lush, rainier route.
Travelers who plan outdoor activities in the afternoons, when showers are less likely, generally find good conditions. Packing a lightweight rain jacket or travel umbrella provides flexibility without weighing down your luggage.
Ocean Conditions and Water Activity Viability
Ocean conditions in December remain inviting for swimmers, surfers, and snorkelers, with water temperatures in the mid 70s Fahrenheit. Seasonal swells increase wave height on certain shores, creating excellent conditions for experienced surfers while challenging novice paddlers.
South shore breaks on Oahu, west shore beaches on Maui, and Kona side of the Big Island typically offer the most consistent rides and clearest underwater visibility. Strong rip currents are possible, so checking local beach reports and swimming at lifeguarded areas is essential.
For families and casual swimmers, choosing calm bays and resort beaches with gentle slopes minimizes risk. Wearing reef-safe sunscreen and respecting marine life ensures that water activities remain enjoyable and sustainable.
Crowds, Events, and Island Atmosphere in December
December is a high demand month because of holiday travel, leading to fuller resorts, longer check in lines, and more crowded popular attractions. Early reservations for tours, car rentals, and restaurants help reduce wait times and secure preferred time slots.
The holiday season also brings special events, including festive markets, illuminated displays, and cultural performances on several islands. Travelers who seek a balance of celebration and relaxation can plan around parade schedules and local gatherings.
Choosing less visited islands or staying in neighborhood accommodations slightly away from resort hubs can restore a sense of space. Midmonth dates just before Christmas and after New Year’s often present a sweet spot for fewer crowds and reasonable weather.
Planning Your December Hawaiian Escape
- Confirm flights and accommodations early to secure better options and pricing.
- Check daily weather and surf forecasts for your specific destination and activities.
- Pack light layers, water resistant outerwear, reef-safe sunscreen, and a reusable water bottle.
- Reserve rental cars, tours, and popular restaurants at least a few weeks in advance.
- Balance itinerary with a mix of leeward beaches, cultural sites, and flexible outdoor time.
