For summer and fall weddings in Minnesota and Wisconsin, we strongly recommend booking at least 12 to 18 months in advance. The outdoor wedding season in both states runs roughly from late May through October, and that compressed window means top entertainment vendors fill their calendars quickly. Saturdays go first, and peak months like June, July, August, and September can be fully booked well over a year out. If you are planning a lakefront wedding on Lake Minnetonka, a barn event in the Wisconsin Driftless Area, or a vineyard reception near Madison, Wisconsin, do not wait until six months out and hope for availability. The earlier you reach out, the more options you have.
