The National Weather Service in Sacramento explains: During the autumn (autumnal) and spring (vernal) equinoxes, the sun’s rays are directly over the equator. Equinox means “equal night” and day and night are about equal all over the world. Due to the tilt of the earth’s axis, the sun’s rays are more directly over the Southern Hemisphere in the autumn (fall) and winter seasons, and directly over the Tropic of Capricorn at the time of the Winter Solstice, which is December 21st at 2:23 PM PST this year. Because Sacramento, CA lies about 38 degrees north of the equator, September 25th and 26th are actually closest to equal days/equal nights in Sacramento.

Enjoy the weekend, the beginning of Fall and remember all the fire restrictions are still in effect – Fall or not.
