In WA state the regulations say that coyotes are open season year round, day or night, and you can hunt at night with nightvision/thermal. EXCEPT, it is illegal to hunt coyotes at night during the general deer and elk modern firearm(MF) seasons, which happens during October-November.
This is what I meant by the "no night coyote hunting" season.
This year Deer MF season is Oct. 12-31, and late general MF season is Nov. 14-17. Elk MF (for the west side of the state where I'm at) season is Nov. 2-13.
So basically night time coyote hunting is closed Oct. 12-Nov. 17. Coyotes may still be hunted during "daytime hunting legal hours" during these dates.
If a person was motivated, i think they could legally hunt at night during a couple of the 1-2 day gaps between MF seasons. I don't think i will try it though, at least not this season.
I'm anxiously awaiting November 18....
