Let’s be honest, there’s never a bad time to visit Oahu. The food is always great, the Waikiki sunsets are always appealing, and the sand is always soft.
But Oahu does change with the seasons in all kinds of ways. The fruit you’ll get in your smoothies, the crowds you’ll find on Kalakaua Avenue, the festivals and culture and yes, the deals too. Here are a few things to keep in mind when planning a trip to Hawaii.
Best time for deals
There are two shoulder seasons for Oahu travel — Spring (April-June) and Fall (Sept-December, though Thanksgiving can be busy.) School’s in session and hotel occupancy is down. That means you’ll find great deals on hotels all over the island and bargain airfares.
Best time for sunshine
The rainy season on Oahu typically runs from October to March and yes, that does cover the winter high season. The best weather tends to coincide with the low season so you get good deals and more sunshine. A tip — become familiar with the windward vs the leeward side of the island. The leeward side tends to have more sun than the windward side so if you’re traveling in rainy season, consider booking your stay on the leeward side. Disney’s Aulani Resort is on the windward side and there’s a Marriott right next door. Honolulu and Waikiki are south coast, but they are still drier than the windward side (around Kailua, where there are lots of vacation rentals) or the North Shore.
Best time for surfing
Surf’s up in winter, especially on the North Shore. The swell starts in November and stays up until mid-February. Beginning surfers, don’t fret — Waikiki Beach is fairly protected and is a good place to learn, year round.
Best time to eat your fruits and veg
Hawaii’s tropical climate means that growing season is year round. But if you want the in season stuff in your smoothie, pick your dates carefully. Avocados are a winter crop — November to February; mangos and papaya get the rest of the year, March through November. Sprouts, mushrooms, hearts of palm, and fresh herbs grow year round. Heads up! Don’t be fooled by the stuff at the farmer’s markets — some of its shipped in. Go to a farmstead if you want to be 100% sure what’s in season.
Best time for Spam
Hawaii’s long relationship with the pink processed meat means that Spam is everywhere, all the time, in your soup, your salad, your sandwich, your musubi (and essential Hawaii snack). But if you want to go all in on Spam, plan your trip during Waikiki Spam Jam in April. The festival fill Waikiki with music and crafts and dozens of different ways to consume Spam. No, you don’t have to like Spam to enjoy the festival, but maybe give it a try?
Best time for music
It seems like every hotel lobby and shopping mall has great live music playing — sometimes you’ll find Hawaiian headliners at no cover bars and casually jamming on hotel patios. But during the Na Hoku Hanohano Awards in early may, everyone who’s everyone in Hawaiian music is in Honolulu. If you want to rub elbows with slack key and ukulele stars, go to Honolulu during May for awards season.
Best time for snorkeling
Hanauma Bay is a beautiful protected circular bay just south of Waikiki and it’s worth a day trip to go snorkeling in these clear waters. The season here doesn’t matter so much but time of day makes a huge difference. First of all, there’s limited parking and if you arrive too late, you simply won’t find a place to park. (There is a bus, but it can take a fair bit of travel time.) The real reason to go early is that the waters are calmer and clearer early in the day. The swell tend to pick up as the day goes on and while it’s still protected and safe for swimming, the churn means poor visibility. The park opens at 6:00 am and yes, it really is worth it to go that early.
Best time to be out and proud
Oahu is LGBTQIA friendly and you’ll find no shortage of hotels, tours, parties, events, that make their visitors feel at home no matter who they love. Hawaii is a land of rainbows, after all. Locals, visitors from the other islands, and travelers from around the world come to Oahu in mid-October for the Honolulu Pride Festival.
Best time for whale watching
From December to April, humpback whales come to the warmer waters around Hawaii to have their babies and nurse their young. But peak whale watching season takes place in February and March when you’d have to glue your eyes to land to avoid seeing these majestic giants. Head to the north shore for the best viewing — or better yet, book yourself on a whale watching cruise.
Best time to fall in love with the ukulele
Seems like there’s a ukulele for sale on every street corner in Waikiki — and there are a handful of excellent ukulele builders on Oahu — Ko’Aloha, Kanile’a, Kamaka — who offer tours. Tour them to find out what a gorgeous koa uke feels and sounds like. But to go deep into the ukulele scene, visit in May for Ukulele Picnic, a festival that brings 5000 plus ukulele lovers to Kaka’ako Park The Ukulele Festival in Kapiolani Park is even bigger; that one’s in July.
Best time for Pearl Harbor
Pearl Harbor is tricky. Currently, you can’t visit the USS Arizona Memorial, but there’s still narrated 30 minute tour of the harbor and Battleship Row. The site is more crowded during peak vacation seasons — summer, winter and spring breaks — but even in low season, tickets can sell out early in the day. The best time to go is when you’ve got tickets — which you can get by making reservations in advance. If you don’t have tickets, you’ll want to arrive at the visitors center first thing in the morning. The box office opens at 7:00 am and while the site takes in nearly 4000 visitors daily, tickets do sell out.
Best time for fireworks
It can seem like a party every TK night, what with the fireworks over TK Hilton Hawaiian Village. This shorter display has been taking place for TK years TK TK TK. But the big shows are exactly when you’d expect, New Year’s Eve and July 4th. Book your ocean facing room in Waikiki early for either of these dates — or just head to the beach with everyone else to watch the show.
Best time to avoid the crowds — and get the deals
Low season on Oahu is in February, when the holidays are over. There’s an unofficial “back to work after the New Year” season and this is it. It means fewer travelers, lower occupancy in the hotels, cheaper flights, and all around better deals. Bonus, the weather is pretty good too!
Best time to hang out with sea turtles
Hawaii’s honu — giant green turtles — nest in springtime, and that’s when you’ll likely see most of them. The good news is they occupy Hawaii’s waters year round and your odds of seeing them are always high. Give them plenty of space if they’re having a beach day and don’t touch them when you join them in the water.
Best time to hike Diamond Head
That peak you see from Waikiki got its name from the glittery rock in the soil. It’s a popular hike because it’s close to town and it’s short. But it’s steep — 99 steps up. The trail is open year round, seven days a week, but the best time to head to Diamond Head is first thing in the morning. It gets hot because the trail is exposed. The park opens at 6:00 am, go first thing then head back to town for a giant breakfast. Hawaiian french toast, anyone?
Best time to visit the Polynesian Cultural Center
The PCC is one of Oahu’s top attractions so it’s busy most days, and more so in high tourist season — winter holidays between Thanksgiving and just after New Year’s, and summer vacation season. Plan your visit not around the crowds or the season, but on the day when you can get the best seats for the luau. The show is truly one of the most remarkable luaus on the island. Book the best seats you can afford, and attend the park that day before you see the show.
