Summer Solstice 2026: Confirmed Longest Day in Portland
The summer solstice occurs annually around June 21, when the Earth’s North Pole is tilted closest to the Sun, resulting in the longest day and shortest night of the year in the Northern Hemisphere. In Portland, this event has been consistently occurring for centuries, with recent measurements showing daylight lasting nearly 15 hours.
Prior to 2026, the longest recorded daylight in Portland was approximately 14 hours and 50 minutes. The event is well-documented by astronomical institutions, and local weather data confirms the sunrise around 5:00 a.m. and sunset around 8:50 p.m. during the solstice.
Historical records indicate that the duration of daylight varies slightly each year due to Earth’s elliptical orbit and axial tilt, but this year’s duration is within the typical range for Portland’s latitude.
“This year’s daylight duration on the summer solstice is approximately 14 hours and 50 minutes, aligning with our expectations based on astronomical calculations.”
