About sunrise and sunset times in Seattle

Sunrise and sunset times in Seattle are computed astronomically from latitude 47.61° and longitude -122.33°, shown in PST (UTC-8) local time using the standard NOAA solar position algorithm.

The day length on 8/29/2026 in Seattle is 13h 36m. This varies throughout the year — typically longest around the summer solstice (June 21 in the Northern Hemisphere, December 21 in the Southern) and shortest around the winter solstice.

Sunrise and sunset are defined as the moment the upper edge of the sun touches the horizon, accounting for atmospheric refraction. "Civil twilight" begins ~30 minutes before sunrise and ends ~30 minutes after sunset.
