Illinois Solunar Calendar — August 2026

The August 2026 solunar calendar for Illinois covers every day of the month, with the major and minor deer movement windows, moon phase, and a fused 0–100 hunt score computed for the state's geographic center (40.35°N, 88.99°W, Central Time). The month moves through the Waning Gibbous, Last Quarter, Waning Crescent, New Moon, Waxing Crescent, First Quarter, Waxing Gibbous and Full Moon phases, and the table below shows when each window opens and closes for that location. Whitetail rut peak in Illinois is early–mid November, so the days closest to that window are the ones to flag early. Archery is open October 1 – mid-January, firearm mid-November (3 days) and early December (3 days) for hunters in the field. Midwest cover is corn/bean ag edges, river-bottom hardwoods, and remnant prairie, which shifts the value of a strong major window — wind in big timber moves scent differently than wind across open ag, and the solunar overlay is most useful when read against that terrain context.
