First Day of Summer
Today (June 21st, 11:06am PDT to be exact) marks the official start of Summer! Summer Solstice. The sun, at its highest point in the sky, will provide the greatest amount of potential sunshine for the vast area of the Northern Hemisphere between the Arctic Circle and the Tropic of Cancer. From this time forward, days will once again begin to shorten, imperceptibly at first, as the track of the sun across the Northern Hemisphere sky starts to lower. The hottest time of year, the height of climatological summer, will still be another three to five weeks away depending upon location.
