Had it ever snowed in Hawaii?

Published in Hawaii Weather 3 mins read

Yes, it has definitely snowed in Hawaii, particularly at its highest elevations. While Hawaii is renowned for its warm weather, pristine beaches, and lush rainforests, snowfall is a recurring phenomenon on the summits of its tallest volcanoes.

Where and When Snow Falls in Hawaii

Snowfall in Hawaii is not a myth; it is a regular occurrence, primarily confined to the Big Island and occasionally Maui. The most frequent and notable snow events happen on:

  • Mauna Kea: This dormant volcano on the Big Island is Hawaii's highest peak, reaching over 13,800 feet (4,200 meters) above sea level. It is the most common place to experience snow. During the wetter winter months, from roughly November to March, it's not unusual for cold air and moisture to combine, delivering snow to its summit area. Recent events have seen accumulations of around 2 inches of white powder at its peak.
  • Mauna Loa: Another massive volcano on the Big Island, also reaching high elevations, experiences similar snowfall patterns to Mauna Kea.
  • Haleakala: On the island of Maui, the summit of Haleakala can also receive snow during particularly strong winter storms, though less frequently and usually with lighter accumulations compared to the Big Island's peaks.

These high-altitude regions stand in stark contrast to the tropical warmth of the Hawaiian coastlines, offering a unique dual climate experience within the same state.

Why Snow in the Tropics?

The phenomenon of snow in a tropical paradise like Hawaii can seem paradoxical, but it's purely a result of elevation. The basic meteorological principles at play include:

  • High Altitude: For every 1,000 feet (300 meters) of elevation gained, the air temperature drops by approximately 3.5 degrees Fahrenheit (2 degrees Celsius). With peaks soaring above 13,000 feet, temperatures at the summits can easily fall below freezing, even when coastal areas are basking in sunshine.
  • Moisture-Laden Air: Hawaii is located in the Pacific Ocean and is constantly influenced by moist air masses. When cold fronts or upper-level troughs pass over the islands during winter, they bring the necessary moisture that, when lifted to the freezing temperatures at the summits, condenses and falls as snow.
  • Kona Storms: These unique Hawaiian weather systems, characterized by southwesterly winds, can draw significant moisture into the islands, often leading to heavy rainfall at lower elevations and substantial snowfall on the mountains.

Visitors and residents often make the trek up Mauna Kea to experience this rare tropical snow, sometimes even building snowmen or attempting to ski or snowboard, creating a truly unique Hawaiian memory.
