Here at the Manitou Lodge, Forks, WA, the 2013 Summer Solstice will occur at 10:04PM on June 20 (see countdown widget below) – BE HERE!. Incidentally, isn’t it remarkable how the Rialto Beach seastacks pictured at left look just like Stonehenge? Must be the light. The solstice (from the Latin sol [sun] & sistere [to stand still]) occurs when the tilt of Earth’s axis in either the northern or southern hemisphere is most inclined toward the sun. This happens twice each year, at which times the sun reaches its highest position in the sky as seen from the north or south pole. Depending on calendar shifts, the summer solstice occurs sometime between December 20 and December 23 in the southern hemisphere and June 20 and June 22 in the northern hemisphere.
Although the summer solstice is an instant in time, the term is also used to refer to the day on which it occurs, the day with the longest period of daylight – except, of course, in the polar regions, where daylight is continuous around the summer solstice.

6/21/2013 Update: Now that the Summer Solstice has come and gone, there’s nothing for it except to start the countdown to the Forks Winter Solstice at 9:11AM PST on 12/21/13, the day on which the sun appears at noon at its lowest altitude above the horizon.
