Kicking off with weather in Hawaii in December, this period presents a unique blend of tropical warmth and winter’s chill, making it an attractive destination for travelers seeking a holiday experience amidst mild temperatures and lush surroundings. As the largest island chain in the world, Hawaii’s diverse geography contributes to a wide range of climate conditions, from the balmy coastal areas to the snow-capped mountain peaks.
Understanding the typical atmospheric circulation patterns in the Hawaiian Islands during December and their influence on weather conditions is essential for planning any trip to this paradise. The prevailing trade winds bring stable and dry weather to the islands, with the North Pacific High and the South Pacific Convergence Zone playing significant roles in shaping the weather patterns.
Hawaiian Island Weather Patterns in December
December in the Hawaiian Islands brings a mix of warm weather and occasional rain showers. The typically tropical climate is influenced by the trade winds and the large-scale atmospheric circulation patterns in the Pacific Ocean.
The trade winds play a significant role in shaping the weather in the Hawaiian Islands during December. These winds, which originate in the subtropical high-pressure belt over the southern Pacific Ocean, blow from the northeast towards the islands. As they move over the ocean, they pick up moisture and heat, resulting in warm and humid air masses that cover the islands. The trade winds also influence the temperature, with the north-eastern parts of the islands experiencing warmer temperatures than the southern regions.
As the trade winds reach the Hawaiian Islands, they meet the prevailing south-westerly winds that blow from the Inter-Tropical Convergence Zone (ITCZ). The interaction between these two wind patterns leads to the formation of clouds and precipitation in the islands. The ITCZ, also known as the Intertropical Front, is a zone of low pressure that extends across the equator, characterized by high precipitation and warm temperatures.
The Impact of the North Pacific High
The North Pacific High, a large high-pressure system that dominates the northern Pacific Ocean, also plays a significant role in shaping the weather in the Hawaiian Islands during December. As the North Pacific High moves towards the west, it pushes the trade winds further south, leading to an increase in precipitation and cloud cover in the islands. The North Pacific High also influences the temperature, with colder air masses moving into the area, resulting in cooler temperatures in the north-eastern parts of the islands.
The Impact of the South Pacific Convergence Zone
The South Pacific Convergence Zone (SPCZ) is another important atmospheric circulation pattern that influences the weather in the Hawaiian Islands during December. The SPCZ is a band of low pressure that extends southeastward from the ITCZ, characterized by high precipitation and warm temperatures. As the SPCZ moves towards the islands, it brings with it warm and humid air masses, resulting in increased precipitation and cloud cover in the area.
The SPCZ plays a significant role in shaping the precipitation patterns in the Hawaiian Islands during December. The zone is characterized by high levels of precipitation, with some areas receiving up to 50% of their annual rainfall during this period. The SPCZ also influences the temperature, with warmer temperatures prevailing in the southern parts of the islands.
December Temperature Ranges in Hawaii – Compare the average high and low temperature ranges in December across various Hawaiian Islands, including Oahu, Maui, Kauai, and the Big Island.
Hawaii’s tropical climate, influenced by the equatorial Pacific, makes temperatures relatively stable across the islands. However, variations in elevation and geographical location lead to distinct temperature ranges across different islands. In this section, we’ll delve into the average high and low temperature ranges in December for Oahu, Maui, Kauai, and the Big Island.
Temperature Ranges across Hawaiian Islands
The temperature ranges vary significantly across the islands, primarily due to elevation and geographical location. Here’s a table comparing the average high and low temperature ranges in December across the selected islands:
| Island | High Temperature Range | Low Temperature Range |
|---|---|---|
| Oahu | 78°F – 85°F (25°C – 30°C) | 65°F – 72°F (18°C – 22°C) |
| Maui | 78°F – 86°F (25°C – 30°C) | 63°F – 70°F (17°C – 21°C) |
| Kauai | 75°F – 83°F (24°C – 28°C) | 62°F – 68°F (17°C – 20°C) |
| Big Island | 75°F – 85°F (24°C – 30°C) | 60°F – 68°F (16°C – 20°C) |
These temperature ranges are influenced by the islands’ elevation. For instance, the Big Island’s Mauna Kea, a dormant volcano with an elevation of over 13,796 feet (4,205 meters), has significantly lower temperatures than the surrounding coastal areas.
Significance of Temperature Variation on Tourism and Agriculture
The temperature variation across the islands significantly impacts tourism and agricultural activities in Hawaii during December. On one hand, stable temperatures and minimal rainfall make December an excellent time for outdoor activities like surfing, hiking, and beach-going.
On the other hand, temperature fluctuations can affect agricultural production. For example, the cooler temperatures in higher elevations favor the growth of coffee plants, which are commonly grown in Hawaii’s cloud forests. However, the warmer temperatures in lower elevations can lead to pest and disease issues, affecting the yield and quality of crops like pineapples and sugar cane.
In December, the average high temperature range is between 78°F and 86°F (25°C – 30°C), with an average low temperature range between 63°F and 70°F (17°C – 21°C). These temperatures make it an ideal time for various agricultural activities, including the harvesting of tropical fruits like papayas and pineapples.
In conclusion, the temperature ranges across the Hawaiian Islands, driven by elevation and geographical location, significantly impact tourism and agricultural activities in Hawaii during December. Understanding these variations is essential for making informed decisions about travel and agricultural planning in the region.
Precipitation Patterns in Hawaii in December
December is a relatively dry month in Hawaii, but the precipitation patterns vary across the islands. The trade winds, which blow from the northeast, bring moist air from the Pacific Ocean, leading to rain showers on windward coasts. In contrast, the leeward coasts experience dry conditions due to the rain shadow effect.
Orographic Precipitation and Heavy Rainfall on the Big Island and Maui
Orographic precipitation is a significant factor in generating heavy rainfall on the Big Island and Maui. When moist air rises over mountains, it cools, and the water vapor condenses, forming clouds and precipitation. This process is illustrated in the following diagram:
Imagine a diagram showing a mountain range with trade winds blowing over it. The winds blow up the mountain, cool, and condense, forming clouds and precipitation. The resulting precipitation is heavy on the windward side of the mountain due to the orographic lift.

Comparison of Precipitation Ranges in Different Districts
The following table compares the precipitation ranges in different districts across the islands:
| District | Average Precipitation in December |
| — | — |
| Windward Oahu | 8-12 inches (20-30 cm) |
| Leeward Oahu | 2-4 inches (5-10 cm) |
| Windward Maui | 10-15 inches (25-38 cm) |
