Number: 759

The first day of Autumn started out with a northwest wind, so I decided to go to my stationary count spot along the Lake Huron shoreline at Harrisville State Park at 9AM. By 6:15 PM, I counted 759 monarchs! Here is the hour by hour count:

Time Monarchs
9-10AM 32
10-11AM 166
11-12PM 79
12PM-1PM 61
1PM-2PM 50
2PM-3PM 185
3PM-4PM 95
4PM-5PM 47
5PM-6:15PM 44
Total: 759


The weather was mostly cloudy with some sun with three rain showers lasting about 20 minutes altogether. The Wind was NW at 2 mph at the start of count, and WNW at 13 mph at the end of count. The Temperature was 62F at the start of the count climbing to 69F before falling to 64F by end of count. The monarchs were about 200' above the beach in the AM, but were then migrating just over the tree tops and just above the beach sand in the PM. I also saw five rainbows at one time over the lake!
