Temperature Fluctuations in December

December is a great time to experience the unique weather patterns in Hawaii, with temperatures fluctuating between coastal and mountainous regions. While the temperatures can vary significantly across the islands, there are some general trends to expect.

Typical Temperature Ranges for Major Cities and Resorts

The temperatures in major cities and resorts across the four main islands of Hawaii (Oahu, Maui, Kauai, and Hawaii) are relatively consistent, with slight variations due to elevation and coastal influences. Here are some average temperature ranges for major cities and resorts in December:

* Oahu: Honolulu (coastal) – 78°F (25°C) during the day and 68°F (20°C) at night, Waikiki (coastal) – 78°F (25°C) during the day and 68°F (20°C) at night, and Kualoa Ranch (mountainous) – 65°F (18°C) during the day and 55°F (13°C) at night.
* Maui: Ka’anapali (coastal) – 82°F (28°C) during the day and 70°F (21°C) at night, Lahaina (coastal) – 80°F (27°C) during the day and 68°F (20°C) at night, and Haleakala National Park (mountainous) – 65°F (18°C) during the day and 50°F (10°C) at night.

During December, the temperatures in Hawaii tend to fluctuate significantly between day and night, especially in mountainous regions. In these areas, the average temperature can drop as much as 15-20°F (8-11°C) at night due to cooling of the air as it rises. In coastal areas, the temperatures are generally more stable, but can still fluctuate by as much as 5-10°F (3-6°C) between day and night.

Comparison of Temperature in Coastal and Mountainous Regions

As mentioned earlier, temperatures in Hawaii can vary significantly between coastal and mountainous regions. In general, coastal areas tend to be warmer and more stable than mountainous regions, which experience more significant temperature fluctuations. This is due to the cooling effect of the ocean, which moderates the temperature in coastal areas, and the warming effect of the sun, which causes temperatures to rise during the day in mountainous regions.

Relationship between Temperature and Humidity in Hawaii during December

The relationship between temperature and humidity in Hawaii during December is complex and influenced by numerous factors, including atmospheric pressure, wind patterns, and ocean currents. In general, higher temperatures are associated with higher humidity levels, as warmth and moisture from the ocean evaporate and rise into the atmosphere. However, the humidity levels in Hawaii can fluctuate significantly due to changes in wind patterns, atmospheric pressure, and other factors, which can lead to periods of low humidity and higher temperatures.
