The latest sunrises of the year occur tomorrow (Fri.) and Saturday. In (downtown) Grand Rapids tomorrow is 8:18 am and on Saturday it’s at 8:20 am. Tomorrow, many kids will be heading to school or waiting at the busstop in total darkness or faint twilight. Skies will be cloudy and that will add to the darkness. So, watch out for the kids tomorrow AM.
The time change occurs this Saturday night. At 3 am early Sunday, we move the clock back one hour. Sunday the sunrise will be at 7:21 am and the sunset at 5:31 pm.
ToToday (Thu.) we have a total of 10 hours and 17 minutes of daylight. That shrinks to 9 hours and 31 seconds at the Winter Solstice. The earliest sunset is 5:08 on Dec. 8th and 9th. The latest sunrise after the time change is 8:14 am on Jan 3. Temperature lags the position of the sun by about one month, so the coldest average temperatures come about one month after the Winter Solstice around Jan. 20.
