What’s the weather like in Hawaii in December sets the stage for a story that combines the tropical climate, festive holiday atmosphere, and outdoor adventures. It’s a tale of mild temperatures, rainfall, and unique microclimates that are influenced by trade winds and ocean currents.
Hawaii’s December weather is characterized by mild temperatures, with average highs ranging from the mid-70s to mid-80s Fahrenheit (23-30°C) across the islands. However, the weather patterns in Hawaii are unique, and the islands’ geography plays a significant role in shaping the climate. For instance, the trade winds and ocean currents have a significant impact on the weather, causing temperature fluctuations on various islands.
December Weather Patterns in Hawaii are Typically Characterized by Mild Temperatures
Hawaii’s tropical climate makes it an ideal destination for a winter escape, with December temperatures consistently mild and pleasant. The islands’ unique geography and ocean currents create a stable and relatively dry climate, perfect for outdoor activities and relaxation.
The temperature in Hawaii during December is influenced by the trade winds, which blow from the northeast and bring cooler air from the Pacific Ocean. This results in a consistent and stable temperature range across the islands, with average high temperatures ranging from 70°F (21°C) to 85°F (30°C) and average low temperatures from 55°F (13°C) to 70°F (21°C).
Influences of Trade Winds and Ocean Currents, What’s the weather like in hawaii in december
The trade winds play a significant role in shaping Hawaii’s climate, particularly during the winter months. These winds bring cooler air from the Pacific, which reduces the temperature difference between the islands and the ocean. As a result, the temperature in Hawaii remains relatively constant, with minimal fluctuations between day and night. Additionally, the trade winds help to maintain a high level of humidity, making the air feel comfortable and warm.
The ocean currents surrounding Hawaii also contribute to the islands’ mild climate. The warm waters of the Pacific Ocean, which are warmed by the equatorial currents, help to moderate the temperature, preventing it from dropping too low. This combination of trade winds and ocean currents ensures that Hawaii’s climate remains stable and pleasant, making it an attractive destination for tourists and residents alike.
Temperature Fluctuations on Various Islands
The temperature in Hawaii can vary slightly from island to island, depending on their unique geography and orientation. The following table highlights the average high and low temperatures in December for various islands in Hawaii:
| Island | Average High | Average Low |
| Oahu | 78°F (25°C) | 63°F (17°C) |
| Maui | 82°F (28°C) | 67°F (19°C) |
| Kauai | 80°F (27°C) | 64°F (18°C) |
| Hawaii (Big Island) | 75°F (24°C) | 59°F (15°C) |
| Molokai | 79°F (26°C) | 62°F (17°C) |
These temperature fluctuations are relatively small, with the highest temperature difference between the islands being around 10°F (5°C). This makes it easy to plan activities and outings on any of the islands, regardless of the temperature.
Conclusion
Hawaii’s December weather is characterized by mild temperatures, making it an ideal destination for a winter escape. The unique combination of trade winds and ocean currents helps to maintain a stable and pleasant climate, with minimal fluctuations between day and night. The temperature in Hawaii can vary slightly from island to island, but the differences are relatively small, making it easy to plan activities and outings on any of the islands.
December is the Wettest Month in Hawaii, Bringing Life to the Islands’ Drought-Prone Areas
December marks the beginning of the wet season in Hawaii, bringing relief to the islands’ drought-prone areas. The warmest month of the year, November, usually precedes this wet season, which sets the stage for the lush and tropical environments characteristic of the islands during the winter months.
December is indeed the wettest month in Hawaii, with the majority of its rainfall occurring on the windward sides of the islands. The Big Island and Maui experience the highest amount of rainfall during this period, with the windward coasts of these islands receiving an average of 12-15 inches (30-38 cm) of rainfall per month. The leeward sides, on the other hand, receive significantly less rainfall, often less than 4 inches (10 cm) per month.
Average Monthly Rainfall in Hawaii
The average monthly rainfall in Hawaii during December varies depending on the specific island and location. However, on average, the islands receive the highest amount of rainfall during December, with the following totals:
– The Big Island: 12-15 inches (30-38 cm)
– Maui: 10-14 inches (25-35 cm)
– Oahu: 8-12 inches (20-30 cm)
– Kauai: 10-15 inches (25-38 cm)
Major Windward Rainfall Events in December
The major windward rainfall events in December are primarily driven by the trade winds, which bring warm, moist air from the northeast. As this air rises over the islands, it cools and condenses, resulting in significant rainfall on the windward sides. Some notable windward rainfall events in December include:
– The Kona low, which affects the leeward coasts of Hawaii
– The Hawaiian Islands are also affected by other low-pressure systems that form in the tropics, bringing heavy rainfall to the windward coasts.
Impact on Hawaii’s Water Sources and Vegetation
The increased rainfall during December has a significant impact on Hawaii’s water sources and vegetation. Some of the key effects include:
- Refilling reservoirs and aquifers: The increased rainfall during December helps to replenish Hawaii’s reservoirs and aquifers, which are essential for supporting agriculture, industry, and domestic use.
- Photosynthesis and vegetation growth: The rainfall during December promotes plant growth, including the lush vegetation that characterizes Hawaii’s tropical environments. The increased photosynthesis rate allows plants to grow at an accelerated rate, supporting the local ecosystems.
- Stream flow and erosion: The increased rainfall during December also leads to a significant increase in stream flow, which can cause erosion in some areas. This, in turn, affects the local water quality and habitats.
- Improved water quality: The rainfall during December also helps to improve water quality by washing away pollutants and sediment from the catchments. This, in turn, maintains the health of aquatic ecosystems.
Difference in Rainfall Patterns between the Big Island and Maui
The rainfall patterns on the Big Island and Maui differ because of their unique geographies. The Big Island is dominated by Mauna Loa and Mauna Kea, two massive volcanoes that cast shadows on the windward sides during the winter months. This shadowing effect reduces the amount of rainfall on the Big Island’s windward sides. Maui, on the other hand, has a more compact island profile, resulting in less shading and more even rainfall distribution.

The lush vegetation in Hawaii during December is a result of the increased rainfall, which supports the growth and development of the islands’ unique ecosystems. Imagine walking through a rainforest on the Big Island, surrounded by towering eucalyptus and ferns, or hiking through the misty valleys of Maui, with the sounds of birds and streams filling the air. These scenes are a testament to the impact of December’s rainfall on Hawaii’s environment.
