Mountain influence: Olympic Mountains shield city from harsh weather
Seattle's location on the western slopes of the Cascade Range and in the rain shadow of the Olympic Mountains has a significant influence on its climate. The mountains act as a natural barrier, protecting the city from harsh weather conditions.
- Blocking cold air:
The Olympic Mountains shield Seattle from cold air masses that originate in the north and east. This helps to keep winter temperatures mild and prevents extreme cold snaps.
- Reducing precipitation:
The Olympic Mountains also reduce the amount of precipitation that reaches Seattle. As moist air from the Pacific Ocean rises over the mountains, it cools and condenses, releasing its moisture as rain or snow on the western slopes. By the time the air reaches Seattle, it has lost much of its moisture, resulting in a drier climate than areas to the west of the mountains.
- Creating a rain shadow:
The Olympic Mountains create a rain shadow effect, which is a region of reduced precipitation on the leeward side of a mountain range. Seattle lies in the rain shadow of the Olympic Mountains, which means that it receives less precipitation than areas to the west of the mountains.
- Moderating temperatures:
The mountains also help to moderate Seattle's temperatures. During the summer, the mountains prevent hot air from the east from reaching the city, keeping temperatures cool and comfortable. During the winter, the mountains help to trap warm air in the Puget Sound region, preventing extreme cold.
Overall, the Olympic Mountains play a vital role in shaping Seattle's climate, making it milder and more temperate than it would be otherwise.
Maritime influence: Puget Sound moderates temperatures
The Puget Sound, a large body of water located west of Seattle, has a significant influence on the city's climate. The sound acts as a natural heat sink, absorbing and releasing heat slowly, which helps to moderate temperatures throughout the year.
- Reducing temperature extremes:
The Puget Sound helps to reduce temperature extremes in Seattle. In the summer, the sound absorbs heat from the air and releases it slowly at night, keeping temperatures cool and comfortable. In the winter, the sound releases heat into the air, helping to keep temperatures mild.
- Creating a more humid climate:
The Puget Sound also contributes to Seattle's relatively humid climate. As the water in the sound evaporates, it adds moisture to the air. This moisture helps to keep the air feeling mild and comfortable, even on hot days.
- Protecting from cold winds:
The Puget Sound also acts as a barrier against cold winds from the north and east. This helps to keep Seattle's winters mild and prevents extreme cold snaps.
- Influencing precipitation patterns:
The Puget Sound also influences precipitation patterns in Seattle. The sound acts as a convergence zone for moisture-laden air masses from the Pacific Ocean. As these air masses rise over the Olympic Mountains, they cool and condense, releasing their moisture as rain or snow. This results in Seattle receiving more precipitation than areas to the east of the sound.
Overall, the Puget Sound plays a vital role in shaping Seattle's climate, making it milder and more temperate than it would be otherwise.
Few extreme weather events: Rare snowfall, occasional heat waves
Seattle is known for its mild and temperate climate, and extreme weather events are relatively rare. However, the city does experience occasional heat waves and snowfall, although these events are typically short-lived.

Most snowfall occurs in the months of December and January, and it rarely stays on the ground for more than a few days. This makes Seattle a great place to live for those who enjoy winter activities without the hassle of heavy snowfall.
Occasional heat waves:
Seattle also experiences occasional heat waves during the summer months. However, these heat waves are typically short-lived, lasting only a few days at a time. Temperatures during a heat wave can reach into the 90s Fahrenheit (around 32 degrees Celsius), but they typically drop back down to more comfortable levels at night.
Why are extreme weather events rare in Seattle?
There are a few reasons why extreme weather events are rare in Seattle. First, the city's location on the Puget Sound helps to moderate temperatures.
