Halloween is almost here and Seattle is about to take a major step towards what some locals call The Big Dark. On Sunday night, Seattleites will see the last 6:00 p.m. sunset of 2025. After Sunday, October 26 the sun will start setting just before 6:00 p.m.
Seattle saw its last 7:00 p.m. sunset of the year last month on Thursday, September 25. According to timeanddate.com, the sun will set in Seattle at 6:00 p.m. on October 26. At the beginning of the month, the sun set at 6:47 p.m. on October 1. By the time Halloween arrives next Friday, the sunset time will be at 5:52 p.m. This has been a gradual, month-long shift towards shorter days—but when November arrives we’ll see a more dramatic change with the end of daylight saving time.

On November 2, 2025, daylight saving time ends and the sunset time will be an hour earlier. This means that we’ll go from a 5:51 p.m. sunset on Saturday, November 1 to a 4:49 p.m. sunset on Sunday, November 2. By the time we get to the winter solstice on December 21, Seattle will be seeing a total of about eight hours of daylight. Compare that to the 16 hours of sunlight at the summer’s peak, and you’ll understand why so many Seattleites buy sun lamps for the winter months.
Seattle’s 7:00 p.m. sunsets will return in early March 2026. In the meantime there is plenty of fall and winter fun to be had. Although it’s always hard to say goodbye to the long days of perfect summer weather in Seattle, the shorter days signal the return of some of our favorite fall festivities!
