A costume contest can shape a family’s Halloween evening, but registration and judging do not happen at the same time. Duluth’s Howl on the Green returns Friday, October 23, 2026, with a Mad Science: Project Zombie theme. Families who want to enter the contest should plan for its earlier registration window rather than arriving when the competition begins.

Howl on the Green costume-contest registration

The city’s current event page lists the free downtown celebration from 6 to 9:30 p.m. Costume-contest registration runs 6–7 p.m., with the contest itself scheduled for 7:30–8:30 p.m. Arriving for the later show is not the same as registering an entry.

Before spending time on elaborate costume additions, ask the organizer about entry categories, participant ages, group entries and any restrictions on props. The published timetable does not establish those rules. Keep expectations clear with children: entering is an opportunity to take part, not a promise of a prize.

Allow time to locate registration and ask where entrants should gather afterward. If one adult is accompanying several children, decide how to stay together while registering. A simple plan prevents the first part of the evening from becoming a rush between separate activities.

Build the evening around the early activities

The city schedules trunk-or-treat from 6 to 7:30 p.m., while supplies last, and a science show at 6:30. Themed activities continue through 9, with the cirque finale listed at 9 p.m. Choose priorities instead of assuming every attraction is available throughout the whole event.

If treats are your child’s main interest, the early window matters more than the finale. If the costume contest is the priority, ask how registration and gathering instructions fit with the science show. Plan a flexible evening around your family’s attention and energy rather than checking every item off.

Explain the theme before arrival. A colorful zombie laboratory may sound exciting to one child and uncomfortable to another. Ask the organizer about particular activities or sensory concerns when that information will determine whether to attend. The family-friendly description is not a detailed guide to every performance.

Agree on a recognizable meeting point and an adult each child can approach if separated. Discuss the departure plan before the evening begins. Leaving after a favorite activity can be a successful outing even if your group does not stay for the late finale.

Prepare a costume you can enjoy wearing

FDA Halloween guidance recommends visible, reflective costumes that do not drag, and avoiding masks that obstruct sight. It also advises checking treats at home and reading labels where allergies matter. Read the full guidance when choosing clothing, makeup and treats for your group.

Try the costume with the shoes and layers that will actually be worn. Check whether the child can walk comfortably, carry a bag and use the restroom without taking apart the whole outfit. A favorite costume is more enjoyable when it works for an evening outside.

For a homemade project, our Duluth Library sewing-machine guide explains the difference between reserving a lab and requesting help. Arrange that separately and early. For another Duluth cultural outing, our Hudgens photography-exhibit guide offers a quieter alternative on a different visit.

Official details were checked October 11, 2026. Recheck the city page for updates, confirm parking and any particular access needs, and arrive in time for your chosen activity. For contest entrants, that means paying attention to registration first.
