Mount Olympus is the highest peak in the Olympic Mountains, a mountain range in the state of Washington, United States. It is also the name of the mythical home of the ancient Greek gods, located in Greece. Both mountains share some similarities, such as being covered with snow and glaciers, but they also have distinct features and effects on the local weather and climate. In this blog post, we will explore how Mount Olympus in Washington and Mount Olympus in Greece influence the weather and climate of the surrounding regions, and how they are affected by global climate change.
Mount Olympus in Washington
Mount Olympus in Washington is part of the Olympic National Park, a UNESCO World Heritage Site that covers almost a million acres of diverse ecosystems, from temperate rainforests to alpine meadows. The park is located on the Olympic Peninsula, a large landmass that juts out into the Pacific Ocean and creates a rain shadow effect for the eastern part of the state. The park receives an average of 140 inches of precipitation per year, most of it falling as rain on the western slopes of the mountains. The eastern slopes are much drier, receiving only about 16 inches of rain per year.
The weather and climate of the park are influenced by several factors, such as elevation, latitude, topography and ocean currents. The elevation ranges from sea level to 7,980 feet at the summit of Mount Olympus, creating a gradient of temperature and precipitation. The higher the elevation, the colder and wetter it gets. The latitude of the park is about 48 degrees north, which means it experiences four distinct seasons, with mild summers and cold winters. The topography of the park is rugged and complex, creating microclimates and variations in wind patterns. The ocean currents that affect the park are the warm North Pacific Current and the cold California Current, which moderate the coastal temperatures and bring moisture to the air.
Mount Olympus is the dominant feature of the park’s landscape, rising above the surrounding peaks and valleys. It has a significant impact on the local weather and climate, especially on precipitation and cloud formation. Mount Olympus acts as a barrier for the moist air coming from the Pacific Ocean, forcing it to rise and cool as it moves over the mountain. This process causes condensation and precipitation, creating clouds and rain on the windward side of the mountain. On the leeward side, however, the air descends and warms up, creating a rain shadow effect that reduces precipitation and cloud cover.
Mount Olympus is also home to several glaciers, which cover about 10 percent of its surface area. Glaciers are masses of ice that form when snow accumulates faster than it melts over many years. Glaciers affect the weather and climate by reflecting solar radiation back to space, cooling the air near their surface, and storing water that can be released as meltwater during warmer seasons. Glaciers also shape the landscape by eroding rocks and sediments, creating valleys and moraines.
However, Mount Olympus and its glaciers are not immune to global climate change. Like ecosystems worldwide, the park is impacted by human-driven climate change. Warmer winters mean some precipitation that used to fall as snow—feeding glaciers—is now falling as rain. Blue Glacier on Mount Olympus, the park’s largest glacier, has receded over one-third of a mile and lost more than 150 feet of ice thickness since 1919. According to a study by Pelto et al. (2019), all glaciers in the Olympic Mountains have lost mass since 1980. The loss of glaciers has implications for water availability, wildlife habitat, hydroelectric power generation and recreation.
Mount Olympus in Greece
Mount Olympus in Greece is part of the Olympus Range, a mountain chain that extends along the border between Thessaly and Macedonia regions. It is also part of the Olympus National Park, a protected area that covers about 100 square miles of forests, meadows and rocky slopes. The park is a biodiversity hotspot that hosts more than 1,700 plant species and 300 animal species, some of them endemic or endangered.

Mount Olympus is the highest and most prominent peak in Greece, and it has a significant impact on the local weather and climate, especially on precipitation and cloud formation. Mount Olympus acts as a barrier for the moist air coming from the Mediterranean Sea, forcing it to rise and cool as it moves over the mountain. This process causes condensation and precipitation, creating clouds and rain on the windward side of the mountain. On the leeward side, however, the air descends and warms up, creating a rain shadow effect that reduces precipitation and cloud cover.
Mount Olympus is also home to several snowfields, which cover some of its peaks and ridges. Snowfields are areas of snow that persist throughout the year, but do not form glaciers. Snowfields affect the weather and climate by reflecting solar radiation back to space, cooling the air near their surface, and storing water that can be released as meltwater during warmer seasons. Snowfields also shape the landscape by eroding rocks and sediments, creating cirques and horns.
However, Mount Olympus and its snowfields are not immune to global climate change. Like ecosystems worldwide, the park is impacted by human-driven climate change. Warmer summers mean some snow that used to persist throughout the year—feeding snowfields—is now melting faster. According to a study by Nastos et al. (2011), the snow cover duration on Mount Olympus has decreased by about 20 days per decade since 1960. The loss of snowfields has implications for water availability, wildlife habitat, tourism and cultural heritage.
Conclusion
Mount Olympus in Washington and Mount Olympus in Greece are both majestic mountains that influence the weather and climate of the surrounding regions. They both act as barriers for moist air masses, creating precipitation and cloud formation on their windward sides, and rain shadow effects on their leeward sides. They both host snowfields or glaciers that reflect solar radiation, cool the air, store water and shape the landscape. However, they both face the threat of global climate change, which is reducing their snow and ice cover, affecting their ecosystems and human activities.
