Protected from strong south wind. Overcast, storms came through later in the night. Sunflower field nearby.

The owner said they started noticing them about the 23rd with the numbers gradually building to well over a few hundred by Sunday 25th. The wind was out of the south in the 20 mph range with higher gusts. The trees were providing good shelter. It stayed windy for about two days. We then had a number of rain showers move through Monday (8/26) and Tuesday (8/27) on/off both days. Temps were in the upper-60s F Sunday and low around 62F. Monday it got to mid-70s and low of 57F. A commercial sunflower field was about 30 meters west. The monarchs were congregating on the north side of a tree shelter belt.
