Time of day you first saw the roost:
6:30 pm they started flying in and around the yard from the fields.

Date the roost first formed:
Last week we had roosts 3 days in a row, then no butterflies for a few days. Yesterday we had a bunch show up again. There was at least 10 roosts spread out on 60 trees along with butterflies sprinkled in groups of 2 or 3.

Nectar sources nearby like clover, alfalfa fields or wildflowers:
Yes all of the above! We have hay fields and fields full of Goldenrod and also my pollinator gardens as we are a Monarch Waystation with Monarch Watch.

Overnight temperatures:
It is 70 right now, low projected at 58 tonight with storms.

Wind direction. Were the monarchs shielded from the wind in this location?: Calm wind at the moment, we are on a ridge so very little protection from wind. The monarchs are all on my line of windbreak Hybrid Willows on the east and north east side of the tree line.

How you counted or estimated the number of adults roosting:
I counted the ones I could see.
