The mild temperatures prevalent in Kauai during December contribute significantly to the island’s appeal as a vacation destination. This comfortable climate enhances the visitor experience, allowing for a wide range of activities and providing a pleasant contrast to colder climates elsewhere.
2. Increased Rainfall
December marks the transition into Kauai’s wetter season. Increased rainfall significantly influences the island’s landscape and visitor experience. The higher precipitation results from shifting weather patterns, including the movement of the Pacific subtropical high-pressure system and trade winds. This shift allows more moisture-laden air to reach the island, leading to greater cloud cover and more frequent rain showers. The mountainous terrain of Kauai also plays a crucial role. Orographic lift, where air is forced upwards by mountains, causes cooling and condensation, further enhancing rainfall, particularly on the windward (north and east) sides of the island.
This increased rainfall contributes to Kauai’s renowned lush vegetation, replenishing rivers and waterfalls. The enhanced flow of water creates spectacular sights, such as the cascading waterfalls of the N Pali Coast, which become even more dramatic during this period. However, heavier rainfall can also lead to occasional trail closures and disruptions to outdoor activities. For instance, the Kalalau Trail, a popular hiking destination, may experience temporary closures due to flooding or landslides. Understanding this increased precipitation allows visitors to prepare accordingly, packing appropriate rain gear and adjusting itineraries based on weather conditions.
Increased rainfall is an integral component of Kauai’s weather in December. While it contributes to the island’s vibrant beauty, it also presents practical considerations for visitors. Recognizing the influence of orographic lift and shifting weather patterns helps one appreciate the dynamic interplay of climate and geography that shapes the island’s environment during this time of year. Planning with awareness of potential weather disruptions allows travelers to adapt and maximize their Kauai experience.
3. Higher Humidity
Higher humidity is a defining characteristic of Kauai’s weather in December, coinciding with the start of the wetter season. Understanding its implications is crucial for visitors to prepare adequately and manage expectations regarding comfort and outdoor activities.
-
Increased Moisture Content
The air holds a noticeably greater amount of moisture during December, resulting in a humid atmosphere. This increased moisture content contributes to the perception of “stickiness” and can make physical exertion feel more strenuous. Visitors from drier climates may find this humidity level more pronounced.
-
Impact on Perceived Temperature
High humidity can make the air feel warmer than the actual temperature, as the body’s ability to cool itself through evaporation is reduced. This can lead to discomfort, especially during physical activity. It’s crucial to stay hydrated and take breaks in shaded areas to mitigate the effects of the humidity.
-
Influence on Rainfall
The increased moisture in the air contributes to the higher likelihood of rainfall. While showers can be refreshing, they can also disrupt planned outdoor activities. Checking weather forecasts regularly and having alternative plans is advisable.
-
Mold and Mildew Growth
The humid environment can promote the growth of mold and mildew. This is especially noticeable in areas with limited ventilation. Accommodations often utilize dehumidifiers to counteract this issue. Visitors should be mindful of this and choose accommodations accordingly.
Higher humidity is an inescapable element of Kauai’s December weather. Recognizing its influence on perceived temperature, rainfall patterns, and potential mold growth allows visitors to prepare effectively, pack appropriate clothing, and manage expectations for outdoor activities. This awareness contributes to a more comfortable and enjoyable experience despite the increased moisture in the air.
4. Stronger Surf
Stronger surf is a hallmark of Kauai’s north shore during December. This seasonal shift in wave patterns results directly from the influence of winter storms in the North Pacific. These storms generate large swells that travel thousands of miles across the open ocean, eventually reaching the Hawaiian Islands. Kauai’s northern exposure makes its coastline particularly susceptible to these powerful waves. The resulting surf can reach impressive heights, transforming typically calm waters into a surfer’s paradise. This phenomenon is a significant component of Kauai’s weather in December, impacting not only ocean conditions but also coastal activities and safety considerations.
The large waves draw experienced surfers from around the globe, seeking challenging breaks and thrilling rides. World-renowned surf spots like Hanalei Bay become focal points for this activity. However, the powerful surf also presents hazards for less experienced swimmers and ocean-goers. Strong rip currents and shorebreaks become more prevalent, increasing the risk of accidents. Heed warnings from lifeguards and exercise caution near the waterline. Understanding the dynamics of these larger waves allows visitors to appreciate the power of the ocean while prioritizing safety. For example, observing the surf from a safe distance offers an exhilarating spectacle without requiring direct interaction with the powerful waves.
Stronger surf, driven by distant North Pacific storms, is a defining feature of Kauai’s December weather. This dynamic element underscores the island’s connection to the broader oceanic environment and its influence on coastal conditions. Recognizing the implications for both experienced surfers and casual beachgoers allows informed decision-making, balancing the allure of the powerful waves with essential safety precautions. This awareness ensures a more comprehensive understanding of the island’s dynamic weather patterns and their practical impact on the coastal environment during this time of year.

Wailua Falls, for instance, becomes even more spectacular during this period. This enhanced flow also benefits the surrounding vegetation, providing essential hydration.
-
Flourishing Tropical Flora
The abundant moisture revitalizes Kauai’s diverse plant life. Native species like the hia lehua, with its vibrant red blossoms, flourish under these conditions. The increased rainfall promotes growth and flowering, resulting in a more colorful and vibrant display of tropical flora across the island.
-
Impact on Hiking Trails
The lush vegetation bordering hiking trails creates a more immersive experience. The vibrant foliage enhances the natural beauty of the surroundings, enriching the journey for hikers. However, increased growth can also encroach on trails, requiring occasional maintenance and potentially affecting accessibility.
-
Microclimate Variations
The interplay of rainfall and vegetation contributes to microclimate variations across the island. Areas with denser vegetation may experience slightly cooler temperatures and higher humidity than more exposed regions. These localized differences further enhance the diversity of Kauai’s natural environment.
The lush vegetation characterizing Kauai in December is a direct consequence of the increased rainfall. This heightened verdancy contributes significantly to the island’s scenic beauty, impacting everything from the drama of its waterfalls to the vibrancy of its flora.

Increased Competition for Accommodations and Resources
Higher demand during peak season often leads to limited availability and increased prices for accommodations, rental cars, and popular tours. Booking well in advance becomes essential to secure desired choices and manage travel budgets effectively. Last-minute bookings often come at a premium or may be unavailable altogether.
-
Impact on Popular Attractions and Activities
Popular sites, such as the Na Pali Coast, Waimea Canyon, and Poipu Beach, experience significantly higher visitor traffic during December.
