What Time Does It Get Dark in Seattle?
The time the sun sets in Seattle varies dramatically throughout the year due to its northern latitude. During the summer solstice in June, sunset can occur as late as 9:00 PM, while in the winter solstice in December, darkness can fall as early as 4:20 PM.
Understanding these seasonal shifts is key to planning your day, especially if you enjoy outdoor activities or need to factor in commute times.
Understanding Sunset Times in Seattle
Seattle’s geographic location significantly influences its sunset times. Located at approximately 47° North latitude, Seattle experiences a wide range of daylight hours throughout the year. The Earth’s tilt on its axis is the primary reason for this variation. During the summer months, the Northern Hemisphere is tilted towards the sun, resulting in longer days and later sunsets. Conversely, during the winter, the Northern Hemisphere is tilted away from the sun, leading to shorter days and earlier sunsets.
Summer Solstice (June)
Around June 21st, the summer solstice brings the longest day of the year to Seattle. Sunset typically occurs around 9:00 PM, offering extended daylight hours for outdoor activities, tourism, and evening events. This is the ideal time to enjoy Seattle’s beautiful parks and waterfront.
Winter Solstice (December)
On or around December 21st, the winter solstice brings the shortest day of the year. The sun sets very early, generally around 4:20 PM. This means that much of the workday occurs in darkness, and planning ahead is essential.
Spring and Autumn Equinoxes (March & September)
During the spring and autumn equinoxes (around March 20th and September 22nd, respectively), day and night are roughly equal in length. Sunset times are around 7:30 PM in September and around 7:30 PM in March. These periods mark the transition between long summer days and short winter days.
Resources for Checking Sunset Times
Accurate and up-to-date sunset information can be found on various online resources. The National Weather Service provides daily forecasts and sunset times.

Factors Affecting Perceived Darkness
It’s important to note that even after sunset, it doesn’t immediately become completely dark. Twilight conditions persist, and the level of darkness can be affected by factors such as cloud cover, light pollution from the city, and the presence of mountains.
FAQs About Sunset Times in Seattle
What is civil twilight?
Civil twilight is the period after sunset when the sun is just below the horizon, and there is still enough light for most outdoor activities.
Does daylight saving time affect sunset times?
Yes, daylight saving time (which starts in March and ends in November) shifts sunset times forward by one hour during the summer months.
How does cloud cover affect sunset times in Seattle?
Seattle is known for its cloudy weather. Cloud cover can make it appear darker earlier, as it blocks the sunlight and shortens the twilight period.

How does the surrounding geography of Seattle affect sunset times?
The surrounding mountains and Puget Sound can affect the way the sun sets. Mountains can block the sun earlier on the horizon, and bodies of water can reflect light and lengthen the twilight period.
