Re: Best time of day and weather for coyote hunting?
I've personally always had best luck early through late morning, and again just before dark, unless a storm with high winds is about to move in. The day before the high winds and blizzards hit can be very productive all day.
Watching clearings is good, if you can have your downwind be in one of these clearings........much better. There are fewer coyotes everywhere this time of year than there were during October, and they are more spread out. Are you seeing fresh coyote sign in the area you're calling?
Sneak into the area, set up where you can watch your downwind side, most coyotes (especially if they've been educated) will come to your downwind side if they come.
Good luck and Good shooting.
