The summer solstice takes place Thursday evening at 10:04 p.m. PDT. Sunrise for the first full day of summer will be 5:21 a.m. Friday morning. The sunset Friday evening will be 9:03 p.m.
The earth is tilted so that the North Pole is at its closest point to the sun and as a result there will be more minutes of sunlight in the Northern Hemisphere than at any other time of the year.
The word solstice is derived from the Latin sol-stitium, or sun-standing. The summer solstice is the time of the year when the sun stops its northern climb and stands briefly before turning back toward the equator.
As seen from Portland, the sun reaches its highest northern point in the sky at 67.54 degrees from the horizon on June 20 and 21 at approximately 1:12 p.m.
From March 21 until September 24, there are more hours of daylight than darkness. After June 21, the days will gradually grow shorter until December 21, the winter solstice.
Current forecast charts show nice weather with sunshine and warm temperatures on July 5. Locals often refer to July 5 as the true start to the summer season. (And by then the earth will be at its farthest distance from the sun, called aphelion.)
