Best Hawaii Events in October 2026 — Ironman Kona, Molokaī Hoe & More
October is the quietest month of the Hawaii travel year and one of the most rewarding. The summer crowds are gone, school is back in session on the mainland, and the islands settle into a rhythm that belongs to locals and savvy travelers. The weather is still excellent, water temperatures remain warm, and October hosts some of Hawaii's most significant annual events.
Ironman World Championship — Kona, Big Island
The Ironman World Championship is the most prestigious triathlon in the world — 2.4-mile ocean swim, 112-mile bike course through lava fields, and a 26.2-mile run along the Kona coast in 90°F heat and cross-winds. Athletes qualify over the course of a year from events worldwide for one of the limited championship slots.
Race day in Kona is a genuine spectacle — the Ali'i Drive corridor fills with spectators, the finish-line chute is emotional, and the town transforms around the event. Unlike most triathlons, the Ironman finish line stays open until midnight to capture the last finishers.
The race: Typically the third Saturday of October (confirm at ironman.com for the 2026 date). Athletes start at 7 AM from Kailua Pier. The finish line is on Ali'i Drive in Kailua-Kona.
Spectating: Free and open to the public along the bike and run course. The finish line area is the best spot — athletes emerge at all hours from late afternoon through midnight. Energy Café at mile 18 of the run course is traditionally where the real suffering is visible.
Travel note: Book accommodation in Kona months in advance if you want to be in town race week. The entire Kona coast books out. Hilo is a 90-minute fallback.
Molokaī Hoe — Men's Outrigger Canoe World Championship
The counterpart to September's Nā Wahine, the Molokaī Hoe is the Men's Outrigger Canoe World Championship: the same 41.2-mile open-ocean crossing from Hāʻena, Molokaī to Duke Kahanamoku Beach in Waikīkī.
Run annually since 1952, the Molokaī Hoe crosses the Kaʻiwi Channel — called "The Channel of Bones" — one of the most challenging stretches of open water in the Pacific. The crossing requires navigating unpredictable swells, currents, and trade winds in traditional Hawaiian canoes.
Typically: Second Sunday of October. Check molokaihoe.com for the 2026 race date.
Spectating: Duke's beach in Waikīkī for the finish. Arrive 4.5–5 hours after the Molokaī start time to catch the lead canoes coming through.
Hawaii International Film Festival — Honolulu, October
The Hawaii International Film Festival (HIFF) is one of the most respected film festivals in the U.S., with a focus on Pacific Rim cinema — films from Asia, Oceania, and Hawaii alongside U.S. premieres. Founded in 1981, it typically runs 10 days in mid-to-late October at the Consolidated Theatres Ward and other Honolulu venues.
What to expect: 100+ films screened, filmmaker Q&As, panel discussions, and awards. Tickets per screening run $15–25. Festival passes available for multiple screenings.
Why go: The programming is genuinely distinctive — not just festival-circuit mainstream films, but Japanese, Korean, Filipino, and Pacific Island cinema that rarely gets wide U.S. distribution. The opening and closing night gala screenings are the most sought-after tickets.
Dates and programming: Released in September at hiff.org.
Maui County Fair — Late September/Early October
If it runs into October (which it typically does over a 4–5 day span), the Maui County Fair at the War Memorial Complex in Kahului is worth building a day around. Local agricultural exhibits, 4-H animals, rides, live Hawaiian music, and the best concentration of local food vendors in one place.
What to eat: Malasadas, poke, Hawaiian BBQ plates, fresh coconut, and shave ice. The fair food is as locally sourced as any farmers market but with the chaotic energy of a county fair.
Halloween in Hawaii — October 31
Halloween in Hawaii has shifted since the 2023 Lāhainā fire, which destroyed much of the historic district that hosted the famous Maui Halloween party on Front Street. The celebration has evolved:
West Maui: The Kāʻanapali Beach Resort area has taken on some of the Halloween festivity that Lāhainā previously held. The Whalers Village shopping center and beachfront hotels host Halloween events.
Oahu: Costumes are everywhere in Waikīkī on October 31. Kalākaua Avenue and the bar corridor along Kūhiō Avenue fill with people in costumes. Several clubs and bars run Halloween-specific events.
Big Island: Hilo has a walkable downtown Halloween scene with local participation. Kailua-Kona's Ali'i Drive hosts trick-or-treating and local events.
Kauaʻi: Kapaa and Poʻipū area events run throughout the last week of October. More community-focused than tourist-targeted.
Aloha Festivals (Continued) — October Events
The Aloha Festivals extend from September into October on several islands. Big Island and outer island events typically run through the first or second week of October. Check alohafestivals.com for confirmed 2026 dates.

What the Weather Is Like in October
October marks the beginning of Hawaii's "winter" pattern, though on the leeward coasts the difference is minimal:
Water temperature: 79–81°F — still excellent for snorkeling and swimming, marginally cooler than September. Air temperature: Waikīkī averages 82–84°F highs, 72–74°F lows. Slightly cooler than summer. Trade winds: Strong and consistent — often the windiest month of the year on exposed coasts. North swell: The first significant north swells of the season typically arrive in late October. North Shore Oahu begins transitioning from summer flat to fall surf. Rain: Windward coasts see more rain than summer. Leeward coasts (Kona, South Maui, Oʻahu's south shore) remain dry.
Planning October Travel
October is one of the best months for independent travelers — hotel rates are near their annual low, tour availability is high, and the major events (Ironman, HIFF, Molokaī Hoe) add texture without overcrowding every destination.
Book: More flexibility than any other month. Kona is the exception around Ironman race weekend — book that immediately if you want to be there.
Surf: If you want to watch big-wave surfing at the North Shore, come back in November–February. October is the transition period; early swells appear but the famous breaks are not yet fully lit.
