As the days cool and the leaves begin to show hints of change (even in sunny Southern California), October in Long Beach brings a fresh rhythm of festivals, culture, and seasonal fun. 

Whether you’re in it for haunted attractions, classic cars, markets, or community gatherings, the city delivers a wide mix of experiences. 

Here’s your guide to the must-see events in Long Beach this October.

1. Queen Mary’s Dark Harbor — September 19–November 2

October in Long Beach wouldn’t feel right without Dark Harbor at the Queen Mary. From September 19 through November 2, the historic ship and surrounding grounds transform into haunted mazes, spooky performances, themed bars, and immersive experiences. 

Whether you’re into jump scares, gothic ambiance, or theatrical encounters, Dark Harbor offers a full range of scares for various age levels. Advance tickets are recommended (and often required for peak nights).

2. 2XU Long Beach Marathon Weekend — October 4–5

For runners, spectators, or anyone who enjoys a celebratory street festival, Marathon Weekend is a highlight. The 2XU Long Beach Marathon includes a full marathon, half marathon, a bike tour, and a 5K. 

Beyond the races themselves, expect a Race Expo & Packet Pick-Up (Friday & Saturday at Marina Green) with vendors, local brands, and community booths. 

On Sunday, the Finish Line Festival includes food trucks, a beer garden, photo ops, and a festive energy along Shoreline Drive and Marina Green. 

3. Japanese Classic Car Show (JCCS) — October 11

Car and auto culture enthusiasts should mark Saturday, October 11 for the 20th Japanese Classic Car Show (JCCS) at Marina Green. 

This event showcases vintage Japanese automobiles, tuning culture, and community pride in one of Long Beach’s most scenic waterfront settings. 

Bring your camera, stroll the rows, and enjoy the craftsmanship, creativity, and car spirit.

4. LBX Glow Festival & LBX Nights Markets

The LBX Hangar continues its role as a cultural hub in Long Beach with October offerings:

These events bring artisan vendors, food, live music, creative installations, and a community vibe. The markets are ideal for local shopping, exploring pop-up booths, and enjoying casual strolls in a fun atmosphere.

5. Halloween Bar Crawl — October 25

If you’re into nightlife and spooky fun, the Long Beach Halloween Bar Crawl on October 25 is an event to consider. 

Expect themed costumes, drink specials, and a self-guided crawl through participating bars and venues. It’s a festive way for adults to engage with the season, socialize, and celebrate.

6. Additional Events & October Highlights

Events at the Aquarium of the Pacific

October at the Aquarium includes regular programming like Shark Lagoon Nights, lectures, exhibit special events, and seasonal outreach. It’s a great spot for families or those interested in marine life with a twist.

2025 Annual Conference & Expo — Oct 8–10

The League of California Cities Annual Conference & Expo takes place at the Long Beach Convention Center October 8 to 10. 

While it’s not a festival in the traditional sense, it draws professionals, civic engagement, exhibitors, and local businesses, making it relevant for those interested in Long Beach’s civic and economic life.

Tips for Making the Most of October

  • Plan & buy tickets early — Dark Harbor and marathon events often sell out or require timed entries.
  • MAP your approach — Many events are spread out (Marina Green, Queen Mary, LBX Hangar, Downtown). Group your visits by geography or day.
  • Dress smart — October days can still be warm, but evenings by the water may turn breezy. Layers are your friend.
  • Transportation & parking — Use public transit, bike, or rideshare when possible, especially for waterfront or high-traffic events.
  • Explore local spots — Many festivals take place near shops, cafés, and galleries—make a full-day outing of it.
  • Mind the schedules — Check event websites closer to the date, as times, access, or special activations may shift.

Why October Works in Long Beach

From haunted attractions to vintage car shows, from markets to marathons, October offers something for almost every interest.
