Let's briefly summarize the weather in Seattle, a city located in Washington State, USA. Many people associate Seattle with the image of a "city of rain," right? In reality, Seattle is considered one of the areas in the U.S. with low sunlight. However, that doesn't mean it rains heavily all year round. Let's take a look at the main features of Seattle's weather!
-
Frequent Rain
-
Seattle is greatly influenced by the marine climate of the Pacific Northwest region.
-
While there are many days of rain, most of it is light drizzle or gentle rain rather than heavy downpours.
-
Especially from fall to spring (approximately October to May), it is the rainy season, with short days and many drizzly days.
-
-
Mild Temperatures
-
Despite its relatively high latitude, Seattle has a marine climate due to its coastal location, making winters relatively mild and summers not extremely hot.
-
Winter: The average temperature in February is around 5-10℃, so freezing cold is rare. It does snow, but due to the coastal location, accumulation is not common.
-
Summer: The average temperature in July and August is around 20℃, so even in midsummer, it is cool with low humidity. Occasionally it gets hot, but there are almost no suffocating tropical nights like in Korea.
-
-
Short Summers, Long Cloudy Seasons
-
Seattle's summers are very pleasant and clear, making them popular among travelers. With abundant sunlight and relatively low humidity, there are many clear days.
-
However, this period is not long. The dry season lasts from late June to late August, and if you miss this time, you will return to the cloudy and rainy season.
-
Due to the frequent rain and long cloudy periods, many people pay attention to their vitamin D intake in daily life.
-
-
Green Scenery All Year Round
-
With so much rain, Seattle and its surrounding areas are lush with trees and forests, allowing for green views all year round.
-
Thanks to this, it has earned the nickname "Emerald City," reflecting the refreshing nature it offers.
-
There are well-established parks and green spaces in the city, and just a short distance away, there are many national parks, lakes, and mountains, making it a favorite for those who enjoy weekend recreational activities.
-
-
Perceived Humidity and Weather Essentials
-
Although located on the coast, summer humidity is relatively low, so it rarely feels sticky. In contrast, winter or spring can see increased humidity due to rain, but it feels different from the tropical humidity experienced during the monsoon season in Korea.
-
For Seattle residents, a rain jacket is often more essential than an umbrella. Since light rain occurs frequently, many people wear a light rain jacket while moving around. Of course, some locals don't even use umbrellas for moderate rain, adding to the unique image of Seattle!
-
In summary, the most significant feature of Seattle's weather is that it is mild throughout the four seasons, but there are many rainy and cloudy days. This allows for various outdoor activities under clear and pleasant skies in summer, and the fact that winters are not harshly cold is also a plus. While the "rainy and cloudy weather" may seem like a disadvantage, the fact that the entire city is surrounded by green nature adds charm to life in Seattle.
If you are planning to travel to or move to Seattle, it would be good to prepare a waterproof jacket that you can easily throw on and pay attention to vitamin D supplementation. Then, you can better enjoy the unique atmosphere created by the rain and fog in Seattle.
