Weather in Hawaii in October: What to Expect for Your Trip

Are you ready for a dash of paradise? If you’re planning your trip to Hawaii in October, pack your bags for a splash of sunshine and a gentle whisper of the tropics.

The Aloha state serves a delightful cocktail of warm temperatures, mild rainfall, and plenty of sun this month.

Average Temperatures

October ushers in a delightful blend of warmth and comfort in Hawaii. Daytime temperatures hover around the mid-80s (Fahrenheit), while the evenings cool down to the low 70s.

So, whether you’re up for a sun-kissed beach day or a chill evening by the shore, October is easily one of the best months to visit Hawaii!

The humidity is moderate too, making your sun-soaked days pleasantly balmy rather than uncomfortably sticky.

Flights and Accommodations in Hawaii in October: How to Save Money on Your Bookings

October is a noteworthy month for travel to the Aloha State, and savvy explorers can secure some serious savings. Let’s dive into how you can keep your pockets lined while planning your trip to paradise.

Book Your Flight Early

When securing affordable flights, the early bird truly does get the worm. Monitor flight deals and be ready to pounce. Airlines often release their lowest fares about four months before, so start your search!

Consider Off-Peak Travel

Traveling in the off-peak periods, like mid-week or late-night flights, often yield cheaper fares. Plus, you’ll avoid the weekend rush and guarantee a more relaxed travel experience.

Average October Flight Costs

With the onset of autumn, flight costs to Hawaii start to dip. While prices can fluctuate due to various factors, you can generally expect to pay somewhere in the range of $400 to $600 for a round-trip ticket from the continental U.S.

Keep your eyes open for deals, as airlines occasionally offer killer sales during this time! But if you don’t feel like refreshing your airline booking app all day every day, sign up for Matt’s Flights newsletter and let someone else do that painstaking work for you.

Speaking of painstaking work…

I spent about five hours on a recent Saturday (July 8, 2023 to be precise), researching round-trip flight costs to Hawaii in October to give you a better idea of what you might expect as you plan your vacation.

Obviously I don’t know where you live, so I did the next best thing and picked three major US cities to depart from – Los Angeles (LAX), Chicago (ORD and MDW), and New York (various airports).

Also since I don’t know which island in Hawaii you will be visiting in October, I searched flights to four of the most popular airports – Honolulu Oahu (HNL), Kahalui Maui(OGG), Lihue Kauai (LIH), and Kona Big Island (KOA).

And guess what, I don’t know your airline of choice, so why not look at multiple options to give us as broad of an overview as possible. That’s why I went with four airlines most of us Hawaii travelers frequently utilize – United, Southwest (no flights from New York), Alaska, and last but not least, Hawaiian airlines (no flights from Chicago).

See how time consuming this can be!

But there was one easy part, the dates I chose were consistent across the board – October 17-23, 2023. There are a couple caveats though since in two instances you will see below using those dates meant a big increase in flight cost so I adjusted them slightly.

That only highlights the fact that the days you choose to fly can greatly impact how much you will end up paying.

What is the Eco Impact of Flights to Hawaii in October

As Andrew and I become more eco-conscious travelers, we have found ourselves researching the carbon emission costs of the various forms of transportation we use.

I will admit currently there is no easy way to completely reduce our carbon footprint especially utilizing air travel – other than not flying anywhere. But we can at least look for flight options that may expend less carbon emissions than others.

That’s why while I was looking up the different cost of flights, I also looked at the estimated carbon emission costs per passenger (represented in kg CO2) on each round-trip flight.

People much smarter than I am can better explain how to come up with these numbers, but I used Google Flights and here is their methodology.

Of the four airlines I researched, only United shows the carbon emissions of each leg of your flight.

Southwest airlines has an estimator calculator but it does not show a precise number for a specific flight. You can only input a departure and arrival city, but this does not take into account if you have a connecting flight or layover.

HNL (Oahu)6509411230474817
OGG (Maui)6588961150462787
LIH (Kauai)67611811310607832
KOA (Big Island)55210671122595772

KOA (Big Island)74790510056531250

Est. Carbon Emissions (kg CO2) per passenger of Alaska and Hawaiian round-trip flights to Hawaii

On all of the different flight data you just looked through, my aim was to find a happy medium between flight cost and travel time and often times this resulted in a lower estimated carbon emissions cost.

I also attempted to avoid any extra long layovers so you could spend more time in Hawaii and less time hoping no one sits next to you in the airport!

Average October Accommodation Costs 

As with flights, Hawaii’s accommodation costs tend to drop a bit in October. You can score a room in a mid-range hotel for around $150 to $250 per night.

If you’re feeling fancy and want to splurge on a luxury resort, be prepared to dish out anywhere from $300 to $600 per night on the low end.

Of course, these are average costs. Prices can vary depending on the specific islands you’re visiting, the exact dates, and how far in advance you book.

So, it always helps to plan ahead and watch for any special offers or discounts!


Think Beyond Hotels

While hotels offer convenience, they can also come with a hefty price tag. Try looking at vacation rentals, bed and breakfasts, or boutique hotels.

They often offer competitive rates and give a unique twist to your Hawaiian experience. But make sure they are fully licensed!

Top Tip: Accommodation prices tend to drop after Labor Day in September. This means that October can be a goldmine for great deals. So be sure to check out your options!

Look for Package Deals

Package deals can sometimes be your best friend. Travel companies offer airfare and accommodation bundle deals that save you a pretty penny. Just ensure you’re comparing costs before you book.

Remember, the key to saving on your Hawaiian vacation in October is planning, being flexible, and thinking outside the box.

Crowds and Festivals in Hawaii in October: What to Know to Avoid Them

As summer fades, the hustle and bustle of the tourist season in Hawaii begins to mellow. October brings a charming tranquility as the crowds of sun-worshippers start to thin out.

However, don’t be fooled into thinking the islands fall silent.

Feast on Festivals

October sees a delightful explosion of cultural festivals. The Aloha Festivals, a series of free cultural events, usually wrap up in late September, but the echoes of vibrant Hawaiian music and dance can still be felt in early October.

The Hawaii Food & Wine Festival is another October spectacle, enticing foodies from far and wide to indulge in local delicacies.

If you considered visiting the Big Island in October, you should think again, unless you are a diehard triathlete. On October 14, the Big Island will host the women’s Ironman World Championships triathlon.

So leading up to and after that date, the Big Island will be full of athletes and spectators taking in this annual event.

It may be less crowded than in previous years since 2023 marks the first year the men’s Ironman World Championship race will be held at a different time and location. Instead, the men visit Nice, France, a month earlier.

Keeping the Crowds at Bay

While these festivals and events attract crowds, they are typically smaller and more manageable than the summer throngs, minus the Big Island, as we just learned.

For those seeking solitude, plan around these events and consider visiting less touristy islands like Lanai and Molokai

One word of advice: Book your accommodations and flights early. Even though October is a shoulder season, the festivals can cause certain areas to fill up quickly.

So, plan ahead, and you’ll be able to enjoy the best of both worlds – the electric energy of Hawaii’s cultural events and the serene beauty of its landscapes, crowd-free-ish!

Things to Do in Hawaii in October That You Don’t Need a Swimsuit For

Outdoor Wonders

October’s mild climate is perfect for exploring Hawaii’s stunning natural beauty. Hiking in Volcano National Park will allow you to witness the awe-inspiring beauty of active volcanoes.

Alternatively, ride horseback in the lush Waipi’o Valley or a scenic drive along the Road to Hana. Just remember your camera!

Hawaii’s Best Beaches in October: Where to Go for Sun, Sand, and Surf
