This increased precipitation plays a vital role in the island’s ecosystem, rejuvenating the landscape and contributing to its lush, vibrant greenery.
-
Frequency and Intensity
Rainfall in December tends to occur in short, intermittent bursts rather than prolonged periods of heavy rain. These showers can vary in intensity, from light drizzles to more substantial downpours. The frequency and intensity can also fluctuate based on location; mountainous areas, particularly the slopes of Haleakal, typically experience more rainfall than coastal regions. Localized showers are common, meaning one area might experience rain while another remains dry.
-
Impact on Outdoor Activities
While increased showers might necessitate adjustments to outdoor plans, they rarely cause complete disruption. Carrying a light rain jacket or umbrella allows for continued exploration even during brief showers. Furthermore, the rain often enhances the beauty of certain natural attractions, such as waterfalls, which become more full and dramatic during this period. Hiking trails, while potentially muddy, offer a vibrant display of flora thanks to the increased moisture.
-
Road Conditions and Safety
Heavier downpours can occasionally lead to slippery road conditions, particularly in mountainous areas. Exercising caution while driving and staying informed about weather updates is advisable. Flash floods, while rare, are a possibility in certain areas during periods of intense rainfall. Adhering to safety guidelines and avoiding risky areas ensures a safe and enjoyable experience.

UV Index and Sun Protection
Even with periods of cloud cover, the sun’s intensity in Maui remains significant. Sun protection, including sunscreen, hats, and protective eyewear, is crucial throughout the day. The reflection of sunlight off the ocean and sand further amplifies its intensity. Awareness of the UV index and taking appropriate precautions helps prevent sunburn and ensures a comfortable and safe experience. This consistent approach to sun protection is essential for maximizing enjoyment of outdoor activities without compromising skin health.
In conclusion, while December in Maui doesn’t experience the constant sunshine of the drier months, the average 6-8 hours of sunshine per day offers ample opportunity to explore the island’s diverse landscapes and engage in a variety of activities.

6. Wind
Moderate trade winds are a defining characteristic of Maui’s weather in December, influencing temperatures, humidity, and overall comfort levels. These winds, predominantly from the northeast, provide a natural cooling effect, mitigating the warmth and humidity associated with the wetter season. The trade winds also play a significant role in shaping wave conditions for surfing and other water sports. Understanding their influence is crucial for a comprehensive understanding of December’s climate.
The trade winds’ impact extends beyond simple temperature regulation. They influence cloud formation and precipitation patterns, contributing to the localized nature of showers. Windward slopes, facing the northeast, tend to receive more rainfall, while leeward areas remain drier. This effect creates distinct microclimates across the island. For example, the slopes of Haleakal often experience cloudier conditions and increased precipitation due to the trade winds forcing moist air upwards, while the west coast enjoys sunnier, drier weather. This localized variation highlights the importance of considering wind patterns when planning outdoor activities.
In summary, the moderate trade winds represent a critical component of Maui’s December weather. Their influence on temperature, humidity, and precipitation patterns shapes the island’s microclimates and contributes significantly to the overall experience. Recognizing the role of these winds provides a nuanced understanding of Maui’s December climate, enabling visitors to anticipate conditions, plan activities strategically, and appreciate the dynamic interplay of natural forces shaping the island’s weather.
7. Evenings
Cooler evening temperatures are an integral component of Maui’s December weather, offering a welcome contrast to the daytime warmth. As the sun sets, temperatures typically drop into the 60s Fahrenheit (high teens to low 20s Celsius), creating a noticeable shift in the ambient environment. This transition influences attire choices, activity planning, and the overall perception of December’s climate. The drop in temperature results from the reduced solar radiation and the influence of the surrounding Pacific Ocean, which moderates temperature extremes. This diurnal temperature variation is a characteristic feature of Maui’s climate, particularly pronounced during the winter months.
The practical implications of cooler evenings are significant. While daytime activities might necessitate light clothing, evenings often require a light jacket or sweater, particularly at higher elevations or in areas exposed to the trade winds. Outdoor dining experiences become more comfortable, and evening strolls along the beach offer a refreshing change from the daytime heat. This temperature shift also influences accommodation choices; some visitors might prefer lodgings with air conditioning for optimal comfort during the warmer parts of the day and cooler evenings. For example, after a day spent swimming or hiking, the cooler evenings offer a pleasant opportunity to relax outdoors without overheating. This balance between daytime warmth and evening coolness contributes significantly to the overall enjoyment of a December visit to Maui.
In conclusion, the cooler evening temperatures in December contribute significantly to the overall weather profile of Maui during this period. Understanding this diurnal temperature variation allows visitors to pack appropriately, plan activities strategically, and appreciate the nuanced nature of the island’s climate. This characteristic temperature shift, combined with other weather factors, defines the experience of a December visit, offering a balance between daytime warmth and refreshing evening coolness. The cooler evenings offer a welcome respite and enhance the enjoyment of various activities, contributing to the island’s appeal as a year-round destination.
