Tuesday, May 31st.  Today the sun will be up for 15 hours and 18 minutes, setting at 9:19.   The moon, 1 day before new, will rise at 5:38 tomorrow morning.  Tomorrow the sun will rise at 6:00.

Let’s preview June skies.  There will be a lot of sun in June and very little night.  The daylight hours will increase a bit from 15 hours and 19 minutes tomorrow to 15 hours and 33 minutes on the 21st, retreating back to 15 hours 30 minutes at month’s end.  At this time of the year the sunset times for Ludington, Interlochen, Petoskey and Mackinaw City are very nearly the same.  However the sunrise times are at their most divergent.  With Ludington’s sunrise being 14 minutes later than Mackinaw City’s.  The altitude of the sun above the southern horizon at local noon will hover around 68 to 69 degrees.  Local noon, when the sun is actually due south will occur at about 1:43 p.m.  Here’s what we’ve been waiting for:  Summer will start on the 21st at 1:16 p.m.

* Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
