Every October the same three things happen at our house. The keiki start negotiating costumes before the calendar even flips. Mary starts scouting sunflower fields for photos, and we start checking the North Shore buoys like it is a sport.
That is the month in a nutshell. Summer crowds are gone and the water is still bath warm. The whole island gets a little goofy about Halloween.
This year has a twist: Halloween lands on a Saturday. Waikīkī is going to be a scene, and we will get to that.
Add pumpkin patches on both sides of the island, the Honolulu Pride parade, and a world championship canoe race finishing on the sand. Throw in a film festival opening with a Sung Kang drift movie, and October fills up fast.
These are the dates we would build a trip around, plus the weather, the water, and the small stuff that trips people up.

October weather, water, and daylight on Oʻahu
October is still summer by mainland standards. Highs in Honolulu sit around 85°F (29°C) and nights drop to about 75°F (24°C). The ocean holds near 80°F (27°C), warmer than most mainland pools.
The trade winds get lazier this month, so you will feel a few sticky afternoons in town. The wet season is just waking up too.
Windward spots like Kailua and Waimānalo pick up quick showers that pass in ten minutes, while Waikīkī and the leeward side mostly stay dry.
Daylight is the thing that surprises people. Sunset slides from about 6:18 p.m. on October 1 to 5:55 p.m. by Halloween, and there is no daylight saving change here.
When your friends back home fall back on November 1, we just stay put.
One more thing, because we live here and think about it every fall. Hurricane season runs through November 30, and this year already reminded us of that on Kauaʻi in September.
Odds are your trip is fine, but read our hurricane season guide so you know what a watch versus a warning means before you need to.
In the water, October is a handoff month. The South Shore surf that pumps all summer fades, and the first real winter swells start knocking on the North Shore by late in the month.
If you see a yellow warning sign at Sunset or Waimea, believe it! Stick to the beaches we list by region and swim where a lifeguard is sitting.
Pumpkin patches and fall farm days
Pumpkins grow here. That still surprises visitors, and the two farms below turn October into the closest thing Oʻahu has to fall. Both sell out of the good pumpkins early on weekends, so morning is your friend.
Waimānalo Country Farms Fall Harvest Festival (September 26 to November 11)
This is the one with the sunflower fields, the hayride, and the fresh squeezed lemonade that our two-year-old now expects as a human right.
It sits on the windward side across from Waimānalo Beach Park, with the Koʻolau cliffs stacked up behind the fields.
The 2026 festival runs September 26 through November 11. Weekends are the full show, 9:00 a.m. to 4:00 p.m. on Saturday and Sunday. Weekdays it opens at 1:00 p.m. and closes at 4:00 p.m., which works nicely after a morning at the beach across the street.
Last entry is 4:00 p.m., so do not roll in at 3:55 expecting a slow stroll. The fields and market stands close at 4:30 p.m.
Let’s talk money first, because there are two price tiers. Monday through Thursday, general admission is $12 and kamaʻāina or military with ID pay $10. Friday through Sunday it bumps to $15 general and $12 kamaʻāina or military.
Keiki two and under get in free, which takes a little sting out of it for young families like ours.
Pumpkins run $2 to $30 depending on size and are not included in admission, and sunflowers are $3 a stem from the market stand. Please do not pick your own flowers, no matter how good the photo would be.
Cash gets you a discount, since cards carry a 3.5% fee plus tax.
A few things that trip people up. There are no reservations for the daytime event, so just show up.
No pets, and no outside food other than water. The entrance has a 9.5-foot (2.9 m) vehicle clearance, so a lifted truck or a tall camper van will not fit.
The farm also asks you to drive slowly through the neighborhood on Lupe Street, and we ask the same. People live there, and somebody’s grandma is usually watering the yard right at the corner.
Bring a real hat, the kind with a brim. The fields have zero shade, and the Waimānalo sun at 1:00 p.m. does not care how cute your photo is.
📍 Waimānalo Country Farms, 41-225 Lupe St, Waimānalo, HI 96795
Details and after-hours picnic bookings are on the Waimānalo Country Farms site.
Aloun Farms 24th Annual Pumpkin Patch (October 17 to 18 and 24 to 25)
Aloun Farms is the West Oʻahu institution. We wrote about the festival years ago, back when it was carnival rides and a petting zoo on Farrington Highway.
Half the island has the same photo of a toddler in a wagon there.
The 2026 patch is different, and you should know that before you go. The farm is calling this year “Back to Our Roots” and moving the patch to its Aloun Country Market on Kunia Road in Waipahu.
It runs two weekends only, October 17 to 18 and October 24 to 25, from 8:00 a.m. to 5:00 p.m. each day. Two weekends is not a lot of chances, so pencil in a backup day in case the first one rains out.
Expect pick-your-own pumpkins, sunflower fields, fresh produce at the country market, and local vendors, in a simpler farm setting than the old carnival layout. Educational field tours are not being offered this season.
Admission details for the new location had not been posted when we wrote this, so check the Aloun Farms pumpkin patch page the week before you go.
Bring a wagon or a big reusable bag either way, because a 20-pound (9 kg) pumpkin gets heavy by the third row of the parking lot.
Go early. Kunia is hot, and by 11:00 a.m. the best pumpkins are already riding home in somebody’s truck bed.
📍 Aloun Country Market, 94-488 Kunia Rd, Waipahu, HI 96797
Talk Story Festival: Pride in Paradise (Friday, October 2)
The city’s Talk Story Festival is Hawaiʻi’s oldest storytelling celebration, and it turns 38 this year. It is free, it is indoors, and it is the kind of evening that visitors almost never hear about.
The 2026 theme is “Pride in Paradise,” with storytellers sharing the islands’ māhū history and the people who carried it. It runs Friday, October 2, starting at 5:30 p.m. at Mission Memorial Auditorium next to Honolulu Hale downtown.
Parking is the usual downtown headache, so use the city’s municipal lot near Beretania and Alapaʻi streets, which is free after 4:30 p.m. that Friday. Details are on the Honolulu Parks and Recreation page.
📍 Mission Memorial Auditorium, 550 S King St, Honolulu, HI 96813
Rainbow Warriors football comes home twice
University of Hawaiʻi football plays two October home games at the Clarence T.C. Ching Athletics Complex on the Mānoa campus.
San José State comes in on Saturday, October 3, and New Mexico visits on Saturday, October 17, both Mountain West games.
The Ching Complex is small, which is the fun of it. You are close enough to hear the pads pop.
Tickets and kickoff times are on hawaiiathletics.com, and campus parking is limited, so get there early or ride TheBus up University Avenue.
Fall break week and the holiday that is not one (October 5 to 12)
Public schools here take fall break from Monday, October 5, through Friday, October 9. That is a very local thing to know, because every pool, playground, and shave ice line on the island fills up with keiki midweek.
If Hanauma Bay is on your list, book that week’s reservation the second the window opens. Same with the Wet’n’Wild slides if you are traveling with kids who need to burn energy.
Then comes Monday, October 12. The mainland calls it Columbus Day or Indigenous Peoples’ Day, and Hawaiʻi calls it Discoverers’ Day, but it is not a state holiday here.
State offices are open. Banks, post offices, and federal offices are closed, so plan your money and mail around that.
Molokaʻi Hoe, the world championship of outrigger paddling (Sunday, October 11)
The Molokaʻi Hoe has crossed the Kaʻiwi Channel every fall since 1952.
Six-man crews from Hawaiʻi, Tahiti, Australia, Japan, and the mainland paddle about 41 miles (66 km) of open ocean. They leave Hale O Lono Harbor on Molokaʻi and finish on the sand in Waikīkī.
The 2026 race starts at 8:00 a.m. on Sunday, October 11. The first crews are expected at the finish at Duke Kahanamoku Beach, fronting the Hilton Hawaiian Village, right around 2:00 p.m.
Awards run on the beach from about 3:30 p.m., and you are welcome to wander over and watch.
Watching is free, and it is one of our favorite things to do all year. Get to the beach by 1:00 p.m., plant yourself near the lagoon with shade and water, and listen for the escort boats before you see the canoes.
Crews keep coming in for hours after the winners, and the last ones get the loudest cheers.
The race site has the full schedule and live tracking: molokaihoe.com. If the channel gets under your skin, our Molokaʻi travel guide covers the island the paddlers leave from.
Neighbor island note for the same weekend. The Ironman World Championship runs through Kailua-Kona on Hawaiʻi Island on Saturday, October 10, with the pro men and women racing the same day.
Kona hotels are packed that week, so book early if coffee farm tours are also on your list.
Honolulu Pride parade and festival (Saturday, October 17)
Honolulu Pride is the state’s biggest LGBTQ+ celebration, and it takes over Waikīkī for a Saturday. Pride week events run October 14 through 18, with the big day on the 17th.
The parade steps off at 3:00 p.m. from Magic Island at Ala Moana and rolls down Kalākaua Avenue through the heart of Waikīkī. Floats, marching groups, and a whole lot of rainbow.
Then the free festival opens at the Waikīkī Shell in Kapiʻolani Park at 5:00 p.m. Expect more than 70 community booths, national and local performers, food, and dedicated ʻohana and kūpuna zones.
Both are free. Do not drive into Waikīkī that afternoon, because Kalākaua closes for the route and every side street backs up.
Walk from your hotel, take TheBus, or get dropped off on the Diamond Head side of Kapiʻolani Park. Details are at honolulupride.com.
Heads up that October 17 is the busiest Saturday of the month: Pride, the Aloun pumpkin patch, and a home football game all land on the same day. Pick a side of the island and stay there.
HIFF46: the Hawaiʻi International Film Festival (October 21 to November 5)
HIFF is the film festival we look forward to more than any concert.
It is the only Academy Award qualifying festival in the state, and it leans hard into Hawaiʻi, Asia, and Pacific stories. Tickets are priced so you can gamble on a film you have never heard of.
The 46th edition runs October 21 through November 5 on Oʻahu, with the main screenings at Consolidated Theatres Kahala and Kapolei and special events around town.
General admission is $17 in advance and $15 for seniors, students, and military, so a family of four can catch a premiere for less than one luau ticket.
The centerpiece this year is DRIFTER, Sung Kang’s film about Hawaiʻi’s 1990s underground drift scene, and he is scheduled to be here to present it. If you grew up here or just love car culture, that one will sell out first.
The lineup also includes Making the Line, a documentary about competitive hula, and a new film marking 50 years of the movement to protect Kahoʻolawe.
Passes and tickets are at boxoffice.hiff.org. Kahala Mall parking is free and plentiful, which is more than we can say for most things in this post.
Halloween on Oʻahu, and this year it is a Saturday
Halloween here runs the full spread, from keiki trick-or-treating in Mililani cul-de-sacs to the biggest unofficial street party in the state. Saturday, October 31, 2026 is going to be a big one.
Waikīkī on Halloween night
Nobody organizes it and nobody needs to. Every year thousands of people in costume walk Kalākaua Avenue from about the Hyatt down past the Royal Hawaiian, and the sidewalks become a slow, glittery parade.
Last year fell on a Friday and the crowd was enormous, with HPD barriers at the corners to stop people from spilling into the street.
Our family rule: go early. From about 6:00 p.m. to 8:00 p.m. it is a costume show the keiki love, and plenty of families are out.
After 9:00 p.m. it turns into an adult party with bar lines down the block and DJs on the patios. Neither is wrong, just know which one you are dressing for.
Do not drive in. Kalākaua traffic on a normal Saturday night is bad; on Halloween the rideshare surge alone will ruin your mood. Walk from your hotel, or bus in before dark and plan to leave on foot.
Haunted Plantation in Waipahu
Ask anyone who grew up here about a haunted house and they will say Haunted Plantation. It runs inside Hawaiʻi’s Plantation Village, a real museum of restored sugar plantation homes, and the actors work the dark lanes between them.
We went years ago and Mary still brings it up.
In past seasons it has run select nights in October, with timed-entry reservations required and no walk-up tickets. Admission has been about $21 a person, with the balance paid in cash at the booth, and it is not recommended for anyone under 13.
This year’s dates were not posted when we checked, so watch the Haunted Plantation site and their Instagram before you plan a night around it. The nights closest to Halloween have sold out in past years, so book the moment dates drop.
📍 Hawaiʻi’s Plantation Village, 94-695 Waipahu St, Waipahu, HI 96797
A ghost walk with a Native Hawaiian storyteller
Hawaiʻi has its own ghost stories, and they are older and stranger than anything a haunted house can build. The night marchers, the huakaʻi pō, are the ones every local kid learns to respect first.
If you want the real version, there is a 90-minute night marchers walking tour in Waikīkī led by a Native Hawaiian guide from a small local company.
It meets at the Kapiʻolani Park bandstand after dark and covers burial sites and old temple grounds most visitors walk past daily. October dates go fast for obvious reasons.
Halloween with keiki
Trick-or-treating is alive and well in neighborhoods like Mānoa, Kailua, Mililani, and Hawaiʻi Kai. If you are staying in a vacation rental in one of them, a bowl of candy on the lānai makes instant friends.
The costume aisles at Target and Don Quijote get picked over by the last week, so shop early or pack from home.
The pumpkin patches above double as your daytime Halloween plan. Mari’s Gardens in Mililani has run a smaller pumpkin patch through October in past years, so check marisgardens.com if you are on the central side.
Book now for November: Hawaiʻi Food and Wine Festival
The Oʻahu leg of the Hawaiʻi Food and Wine Festival lands November 5 through 8, right after HIFF, and the good tickets sell out in October.
The festival opens on Hawaiʻi Island October 16 to 17 and moves to Kāʻanapali on Maui October 23 to 25 before closing here.
Two Oʻahu events we have circled. The FEAST Summit runs Thursday, November 5 at the Sheraton Waikīkī.
The Breakfast Club brunch takes over the Hyatt Regency Waikīkī on Sunday, November 8, with Koko Head Café’s Lee Anne Wong cooking. Most tasting events are 21 and over. The full schedule is at hawaiifoodandwinefestival.com.
Evenings run early, so plan the dark hours
By the last week of October the sun is gone before 6:00 p.m., which catches a lot of first-timers with a whole evening and no plan. A few things we do.
Friday nights, the Hilton Hawaiian Village fireworks go off over the lagoon after dark, and the beach fronting it is free. Get there 20 minutes early and sit on the sand.
Downtown, the ʻIolani Palace grounds and the old buildings on King Street are a different place at night. Lopaka Kapanui, the island’s best known ghost storyteller, runs a 90-minute ghosts of old Honolulu walk that meets at the King Kamehameha statue at 7:00 p.m.
Street parking on King and Punchbowl is free after 6:00 p.m., which is the only time we ever say that about downtown.
And on any clear night, drive up to Tantalus for the city lights. Take it slow on the switchbacks. The road is one lane in spots, and the residents know every curve better than you do.
Tips for visiting Oʻahu in October
Rates drop. October is shoulder season, so Waikīkī hotels and the Ko Olina resorts price lower than summer or the holidays, and the beaches feel it too. It is one of the best value months of the year.
Pack for two climates. Slippers, sunscreen, and a hat for the leeward side, plus a light rain shell if you are heading windward or up a trail.
Bring reef-safe sunscreen from home, because Hawaiʻi law bans the common stuff and hotel gift shops price the compliant bottles accordingly.
Rental car folks, mark two dates: Kalākaua Avenue closes for the Pride parade on October 17 and turns into a crowd on October 31. Park the car and walk both days.
Our getting around Oʻahu guide covers TheBus, Biki bikes, and when a car is worth it.
Whales are not here yet. The first humpbacks usually show up in November, so save the whale watch money for a later trip and spend it on a hayride.
Fall break (October 5 to 9) is when local families travel too, so interisland flights and Aulani fill up. If you can pick your week, the second half of October is quieter everywhere except Waikīkī on Halloween.
Our October, if we had to pick
The first Saturday at Waimānalo Country Farms while the sunflowers are fresh, and the second Sunday on the sand for the Molokaʻi Hoe finish.
Pride on the 17th. A Kahala HIFF screening on a rainy weeknight. Then Halloween on Kalākaua with the keiki, until the sugar crash sends us home.
That is a full month, and every one of those is free except the farm and the movie. October on Oʻahu rewards people who show up.
