At 11 a.m. on Saturday, October 24, judging starts at Potso Dog Park. Any dog that shows up at 11:01 is a spectator. Tigard Parks & Rec says it plainly on the city's event listing: dogs arriving after 11 a.m. can't enter the contest.
Tigard has no single Halloween night. It has a run of short windows spread over ten days, from October 22 to October 31, and almost every one has a start time, a cutoff, or a split hour that shapes who comes. The library's last ofrenda drop-off window ends Saturday the 24th. The dog contest closes entry at 11. Main Street gives its first hour to one group of kids and its last ninety minutes to everyone. Halloween itself, a Saturday this year, starts with a morning by the creek. If you know the clocks, the week is easy to plan.
| When | What | Where | The clock that matters |
|---|---|---|---|
| Thu, Oct. 22 – Sat, Oct. 24 | Día de los Muertos Community Ofrenda drop-off | Tigard Public Library | Final drop-off window, after an earlier one Oct. 15–17 |
| Sat, Oct. 24, 10:30 a.m. – noon | Howl O'Ween Canine Costume Contest | Potso Dog Park, 7960 SW Hunziker St. | Judging starts at 11 sharp, and no late entries |
| Fri, Oct. 30, 3:30 – 6 p.m. | Trick or Treat Main Street | Main Street, downtown Tigard | 3:30–4:30 is a quieter hour for young and neurodivergent children |
| Sat, Oct. 31, morning | Tricks, Treats, and Beavers | Tent across from the library, 13500 SW Hall Blvd. | Morning only, with no preregistration |
| Sun, Nov. 1 – Mon, Nov. 30 | Community Ofrenda on display | Tigard Public Library | Open all month |
The last ofrenda drop-off is open now
This post goes up on Thursday, October 22, the first day of the Tigard Public Library's second and final drop-off window for its Día de los Muertos Community Ofrenda. The first window ran October 15 through 17, and this one runs through Saturday, October 24, according to the city's community events calendar. The library is inviting community photos and calaveras for the display, which goes up on November 1 and stays through November 30, according to the city's calendar entry.
The timing matters because this is the last chance to contribute. The ofrenda is a month-long display built from what neighbors bring in over two short drop-off windows, and the second one closes the same Saturday as the dog contest. If a photo belongs on that altar, take it to 13500 SW Hall Blvd. by Saturday.
Saturday the 24th belongs to the dogs, and the clock is strict
Two days later the week moves across town to Potso Dog Park on SW Hunziker Street for Tigard Parks & Rec's annual Howl O'Ween Canine Costume Contest. The event runs from 10:30 a.m. to noon, but the useful part is the first thirty minutes. Here's how the morning runs:
- 10:30 a.m. Check-in opens. The city asks entrants to leave extra time for registration forms and waivers.
- 11:00 a.m. Judging begins "promptly." Late arrivals can't enter.
- 11:00 a.m. to noon. Judging runs, and everyone else can watch.
Six categories are open, and they reward different kinds of effort. They are Best in Show overall, most creative or original, best family or group costume, best celebrity, movie, TV, or viral-video character, cutest, and best human and dog look-alike. The family and look-alike categories let the owners join in. So this Saturday-morning event at a dog park isn't only for dogs. It's for households where the dog is part of the costume plan.
For anyone also thinking ahead to the 24th's afternoon, keep the contest separate from the harvest festival at Winona Grange on SW Seneca Street. That event is in Tualatin, not Tigard.
Friday the 30th splits Main Street in two
The downtown event is the clearest example of a clock picking the crowd. Tigard Downtown Alliance runs Trick or Treat Main Street on Friday, October 30, from 3:30 to 6 p.m., with trick-or-treating at participating businesses along Main Street.
The organizer divides those two and a half hours on purpose. From 3:30 to 4:30 p.m., the street is set aside for young children and neurodivergent children, so they can trick-or-treat "in a quieter and more relaxed setting." From 4:30 to 6 p.m., all kids and families are welcome. Volunteers and police will watch the crosswalks, and traffic will be limited.
The first hour, from 3:30–4:30 p.m., is dedicated to young children and neurodivergent children, so they can enjoy trick-or-treating in a quieter and more relaxed setting.
The event hasn't always been set up this way. A 2019 Tigard Life listing gave the hours as 4 to 6 p.m. and said about 50 businesses usually took part. By 2024, KPTV's Halloween roundup was already describing the 3:30 to 4:30 quiet hour. So the event has grown by an early half hour, and that extra time went to the kids who do best with less noise.
That 2019 business count is a historical number. This year's listing doesn't name the participating storefronts, so the best plan is to walk Main Street and look for open doors. For families with a toddler and an older sibling, the split can work as a relay. Do the quiet hour first, then stay as the street fills up after 4:30.
Halloween itself starts by the creek
On Saturday, October 31, the week moves outdoors and into the morning. Tualatin Riverkeepers is setting up a free "Tricks, Treats, and Beavers" tent across from Tigard Public Library, with beaver-themed activities, stickers, coloring pages, and candy for all ages. You don't need to preregister. The Eventbrite listing gives the hours as 10 a.m. to 1 p.m., while the Riverkeepers' own event page lists 10 a.m. to noon. Arriving in the late morning is the safe bet.
The tent is there because of a work party. On the same morning, from 10 a.m. to 1 p.m., Riverkeepers is running "Beaver Pond Habitat Enhancement in Tigard," where volunteers pull weeds and plant habitat-supporting plants along the pond bank. Tools, safety gear, snacks, coffee, and instruction are provided. The bank is uneven, so sturdy shoes make sense. The Tualatin Soil and Water Conservation District is thanked as a supporter, and volunteers sign up through the event's Eventbrite page. An earlier Riverkeepers work day at the same site on October 11 focused on ivy and blackberry removal and building habitat piles to prepare for planting. Halloween morning is the follow-up.
This work is part of a much longer effort. The Fanno Creek restoration partnership, whose partners include the City of Tigard and Clean Water Services, reports restoration work in the watershed going back to 2004, according to Tree for All. The paved approach is newer. The city's Fanno Creek Trail project reports that the segment from the library to Milton Court reached substantial completion on January 8, 2025, so walking or biking in for the morning is an option.
Each window this week is set up for a different crowd. Saturday morning at Potso is for dog owners, the first hour downtown is for younger kids, and the time after 4:30 is for every family. Halloween morning asks a different group for something else. Neighbors who want to spend an hour on a pond bank can do that, and families with small children can stop at a tent and pick up some candy without staying for the work. Both happen at the same address, at the same time, on the one day most people expect to center on trick-or-treating after dark.
Then the library takes over for November
On Sunday, November 1, the Community Ofrenda built from contributions dropped off in October goes on display at Tigard Public Library and stays up all month. The Halloween events last an hour or two each. The ofrenda is the one thing from this week you can visit any day in November, and it holds whatever the community brought in by Saturday the 24th.
At The Lankheet Group, we keep track of Tigard's calendar the same way we track its market, because both affect what it's like to live on a given street. If you live on one of the blocks that fill with trick-or-treaters this month and you're curious what your home would bring today, we'll put together a free, no-pressure home valuation whenever you're ready.
