Hawaii’s iconic Mauna Kea volcano has received an unusual dusting of snow, transforming the typically tropical landscape into a winter wonderland and surprising residents and tourists alike. Images of the snow-capped summit quickly flooded social media this week, showcasing the volcanic peak blanketed in a thick layer of white—an incredible sight for those more accustomed to Hawaii’s sunny beaches and lush green landscapes.
The snowfall comes courtesy of an unusual atmospheric disturbance bringing freezing temperatures to the islands. According to Maureen Ballard, a senior meteorologist with the National Weather Service (NWS) in Honolulu, an upper-level atmospheric shift pulled in cold air, which then mingled with moisture carried by easterly winds. The resulting conditions created a rare recipe for snow, as freezing temperatures at high altitudes turned the moisture into snowflakes instead of rain.

While Mauna Kea’s summit sees snow occasionally in winter, snowfall in October is a little early even for the Big Island. Though there aren’t precise measurements of the snow cover on these high peaks due to a lack of observation stations at that altitude, meteorologists say low-elevation areas have received around four inches of rain.
Hawaii’s wet season, which typically spans from October to April, has arrived in full force, with forecasts showing continued rain showers and the potential for flash flooding in lower regions.
In addition to the snowy spectacle, the National Weather Service issued warnings for residents, especially those living at lower elevations near Mauna Kea. With moderate to heavy showers hitting already saturated ground, there’s an increased risk of flash flooding and runoff.
The island faced a similar situation last December, when both Mauna Kea and nearby Mauna Loa were covered with snow after a significant cold front. This time around, forecasters say the conditions could bring even more snowfall if freezing temperatures persist.
Mauna Kea’s height plays a key role in its occasional snowfall. The mountain’s summit reaches nearly 14,000 feet above sea level, but if measured from its base beneath the ocean, it surpasses even Mount Everest, making it the world’s tallest mountain by this measure. Due to its elevation, Mauna Kea is no stranger to winter-like conditions, with blizzard warnings issued several times in past years.

The recent cold snap may be short-lived, but it has captivated locals and visitors, giving Hawaii’s Big Island a rare glimpse of winter on its highest peak. For now, residents are being advised to take extra caution on mountain roads as the icy conditions persist. The frosty scenery may not last long, but the unforgettable sight of a snow-covered Mauna Kea is likely to leave a lasting impression on all who witness it.
