What is the weather in Hawaii like in December, the most anticipated and magical month of the year, where temperatures dip slightly and the sunshine hours are more predictable than ever before. The tropical climate in Hawaii, characterized by its geographical significance and the role of ocean currents, paints a beautiful picture of mild temperatures, moderate humidity, and gentle trade winds.
Average temperatures in December range from mid-70s to mid-80s Fahrenheit, while humidity levels are relatively stable at around 60-70%. The trade winds play a crucial role in shaping the temperature and humidity conditions in the region, bringing a refreshing breeze that makes the climate feel even more pleasant.
Overview of Hawaii’s Tropical Climate

Hawaii is a tropical paradise located in the Pacific Ocean, about 3,800 kilometers southwest of the North American continent. The unique location of Hawaii, situated near the equator, contributes to its tropical climate, characterized by high temperatures and high humidity levels throughout the year.
One of the most significant factors contributing to Hawaii’s tropical climate is its geographical location in the tropics. The state’s proximity to the equator ensures that it receives a consistent amount of sunlight throughout the year, resulting in high temperatures and intense sunshine. The tropical climate in Hawaii is also influenced by the trade winds, which bring warm, moist air from the equator and circulate it across the islands.
In terms of temperature, Hawaii’s average temperature ranges from 70°F to 85°F (21°C to 30°C) throughout the year, with the warmest months being July and August. During December, the average temperature in Hawaii is around 70°F to 80°F (21°C to 27°C), making it an ideal time to visit for those who prefer milder weather. The humidity levels in Hawaii are also high, ranging from 60% to 80% throughout the year, with the most humid months being June, July, and August.
The trade winds play a significant role in regulating temperature and humidity levels in Hawaii. These winds blowing from the northeast bring cooler, drier air from the polar regions, which helps to moderate the temperature and maintain a more stable climate. During the summer months, the trade winds also help to reduce the humidity levels, making the weather more pleasant.
Temperature and Humidity Levels in December
During December, the average temperature in Hawaii is around 70°F to 80°F (21°C to 27°C), making it an ideal time to visit for those who prefer milder weather. The humidity levels in Hawaii are also relatively high during this time, ranging from 60% to 75%. The trade winds continue to play a significant role in moderating the temperature and humidity levels, ensuring a stable and pleasant climate throughout the month.
According to the National Oceanic and Atmospheric Administration (NOAA), the average temperature in Hawaii during December is around 75°F (24°C), with an average relative humidity of 65%.
The temperature and humidity levels in Hawaii during December are influenced by the trade winds, which bring cooler, drier air from the polar regions. This helps to moderate the temperature and maintain a more stable climate, making it an ideal time to visit for those who prefer milder weather.
Role of Ocean Currents
Ocean currents also play a significant role in shaping Hawaii’s tropical climate. The warm, tropical waters of the Pacific Ocean surrounding the islands contribute to the high temperatures and humidity levels. The Kuroshio Current, a warm ocean current originating from the Gulf of Alaska, flows eastward along the northern coast of Hawaii, bringing warm, nutrient-rich water that supports the growth of marine life.
The trade winds also help to moderate the temperature and humidity levels by bringing cooler, drier air from the polar regions. This helps to reduce the humidity levels and maintain a more stable climate throughout the year.
Influence of Topography
Hawaii’s unique topography also plays a significant role in shaping its tropical climate. The state’s mountainous terrain creates a rain shadow effect, where the prevailing winds drop most of their moisture on the windward sides of the islands, leaving the leeward sides drier and more sunny. This results in a diverse range of climates across the islands, from the tropical rainforests on the windward sides to the arid desert climates on the leeward sides.
The trade winds and ocean currents combine to create a unique and stable climate in Hawaii, making it an ideal destination for those seeking a tropical paradise.
