Tropical, softened by the trade winds: 27 to 31°C all year round in Honolulu, dry south and west coasts, a wetter east coast and mountains, a showery season from November to March, and giant swells on the North Shore in winter. The best time to visit Oahu is April, May, June, September and October, with temperatures reaching 30-31°C (August). By contrast, January, February, March, July, August, November and December are generally less favourable (less pleasant weather or big crowds, depending on the destination), though a trip is still possible with a bit of planning.

Why go to Oahu and Honolulu?
Oahu is the island where Hawaii lives and works: a million people, a capital of towers at the foot of green mountains, a naval base and traffic jams. It is also where the archipelago's history is easiest to read, from ʻIolani Palace, where the last Hawaiian monarchs reigned, to the Bishop Museum, which holds the chiefs' feather capes, and on to the Pearl Harbor memorial, where the wreck of the USS Arizona still lets drops of fuel oil rise to the surface. Honolulu is visited like a city, with its neighbourhoods: Chinatown, Kakaʻako and its murals, Mānoa and its valleys.
Waikīkī, a few minutes from downtown, remains the place where modern surfing was born for the whole world, with the beach boys of the 1920s and Duke Kahanamoku. You learn to stand up on a board in gentle waves, climb Diamond Head crater at dawn and swim among the turtles at Hanauma Bay. The district is dense and touristy, but everything can be done on foot, and the bus links the rest of the island.
Yet an hour is all it takes to find the countryside. The North Shore keeps its surf-shack villages and its beaches where the biggest waves in the world break in winter, the windward coast lines up the white beaches of Kailua and Lanikai beneath the Koʻolau cliffs, and the east coast ends at the Makapuʻu lighthouse, a whale-watching post. Oahu is the gateway to the archipelago, and a good first stop before Maui or Kauai.

Safety in Oahu and Honolulu: should you be worried?
Oahu is a safe destination, with the precautions of a big city. Break-ins in hire cars are frequent at trailheads and beaches, so leave nothing visible. In Waikīkī and Chinatown, homelessness is visible in the evening, and pickpockets work the crowds. The sea is the real danger: drowning is the leading cause of death among visitors to Hawaii. Do not swim on the North Shore in winter, respect the flags and the lifeguards, and beware of the shorebreak at Sandy Beach and Makapuʻu. The Koʻolau ridge trails, slippery and narrow, lead to helicopter rescues every year, and some, such as the Haʻikū Stairs, are off limits. Stay 3 metres from turtles and 15 metres from monk seals. Insurance covering medical care in the United States is essential.

Honolulu's beach district fits into 3 km of sand between the Ala Wai canal and Diamond Head crater. You stay there, learn to surf at Canoes or Queens, dine and go out, all on foot. The Moana and the Royal Hawaiian, grand hotels from the early 20th century, are worth a visit for their verandas. To the east, Kapiʻolani Park, the aquarium and Kaimana beach lead to the foot of Diamond Head, whose trail is done at sunrise by reservation. The Kalākaua Avenue promenade comes alive in the evening with street musicians.
Downtown, Chinatown and Kakaʻako
The historic centre brings together ʻIolani Palace, the Kamehameha statue, the coral church of Kawaiahaʻo and the Capitol with its palm-shaped columns. Chinatown, next door, keeps its fish markets, its herb and flower lei shops, and its cocktail bars in the evening. Kakaʻako, between downtown and Ala Moana, is a former industrial district covered in large murals, with breweries and food halls. The Bishop Museum, 10 minutes away, is the great museum of Polynesian culture.
Pearl Harbor
30 minutes west of Waikīkī, the national memorial can be visited in half a day: the USS Arizona programme with a Navy boat, by reservation, the visitor centre and free museums, then, with separate tickets, the battleship Missouri, the aviation museum on Ford Island and the submarine Bowfin. Bags are not allowed; there is a paid bag storage at the entrance. Arrive early, as the car park fills up fast in the morning and the afternoon is often hot.
The North Shore
From Haleʻiwa to Sunset Beach, 15 km of beaches and surf villages. In winter, the waves at Waimea Bay, Pipeline and Sunset are watched from the sand, with the competitions in December and January. In summer, the sea calms down for snorkelling at Shark's Cove and jumping off the rock at Waimea Bay. Waimea Valley has a botanical garden and a waterfall at the end of a paved path. The garlic shrimp food trucks of Kahuku and the shave ice of Haleʻiwa make lunch. Allow an hour from Honolulu, more at weekends.
The windward coast, from Kailua to Kualoa
The Pali pass, with its lookout over the Koʻolau cliffs and the battlefield where Kamehameha I conquered the island in 1795, leads to Kailua and Lanikai, two of the finest beaches in the archipelago. To the north, the road follows Kāneʻohe Bay to Kualoa Ranch, whose valley was used as a set for Jurassic Park and can be visited on a guided tour. The Byodo-In Buddhist temple, a replica of an 11th-century Japanese temple, is tucked away in the Valley of the Temples.
The south-east coast, from Hanauma to Makapuʻu
Route 72 follows the driest coast on the island: the Hanauma Bay marine reserve, by reservation, the Koko Crater trail, an old railway track of more than 1,000 steps straight up to the summit, the Hālona blowhole, Sandy Beach and its bodyboarders, then the Makapuʻu lighthouse above Makapuʻu beach and Rabbit Island. It is the ideal half-day loop from Waikīkī, to combine with Kailua on the way back.
How many days, and which itinerary in Oahu and Honolulu?
Four days cover Waikīkī, Diamond Head, Pearl Harbor, Hanauma Bay and a day on the North Shore. Six days add the windward coast, Honolulu as a city and some leeway for reservations. Oahu is often combined with another island, for ten days to two weeks in total.

The essentials (4 days)
Day 1: arrival, Waikīkī, first surf lesson at Canoes, sunset on the beach. Day 2: Diamond Head in the first slot, then Pearl Harbor in the afternoon, or the other way round depending on your Arizona reservation.

Day 4: the North Shore by the central road, Haleʻiwa, Waimea Bay, Pipeline and Sunset, back along the windward coast and Kualoa.
Honolulu and the island (6 days)
The four days of the essentials, plus a day in the city, ʻIolani Palace in the morning, Chinatown at lunchtime, the Bishop Museum in the afternoon and dinner in Kakaʻako, and a day on the windward coast, Byodo-In, kayaking to the Mokulua islets from Kailua and the Lanikai Pillbox trail at sunset. A night on the North Shore, in the coast's only big hotel or a rental, lets you watch the surfers at dawn.
Oahu and Maui (10 days)
Four days on Oahu following the essentials, then a 40-minute flight to Kahului. Six days on Maui: sunrise at Haleakalā, the Road to Hana with a night at the end, a boat trip to Molokini and two beach days on the west coast. Book Diamond Head, Hanauma Bay, the Arizona and Haleakalā as soon as your dates are fixed.
How to get to Oahu and Honolulu and get around?
There is no direct flight from Europe: expect a connection on the US West Coast, Los Angeles, San Francisco or Seattle, for 19 to 22 hours of travel to Daniel K. Inouye airport. The return is often overnight. Honolulu is the hub for inter-island flights to Maui, Kauai and the Big Island, taking 35 to 50 minutes.
TheBus network covers the whole island, including the North Shore and the windward coast, with the HOLO card: $3 per ride valid for two hours, about €2.60, and $7.50 a day, about €6.50, capped automatically. The Skyline elevated metro links the airport to Kalihi and the west of the island, but not yet downtown, and its route does not plan to serve Waikīkī.
For Waikīkī, Honolulu and Pearl Harbor, a car is unnecessary and expensive: hotels charge $40-60 a night for parking. Hire one only for a day or two for the North Shore, the windward coast and the south-east coast, from €60 a day, and return it before going back to the hotel.
Honolulu's traffic jams are among the worst in the United States at rush hour, from 6am to 9am and from 3pm to 6pm, especially on the H-1 freeway. The Biki bike-share scheme serves Waikīkī and downtown, handy for short trips.
Where to stay in Oahu and Honolulu?
Waikīkī has most of the island's hotels, from simple buildings on the inner streets at €150-220 a night to the grand beachfront hotels at over €600. Ocean-view rooms cost considerably more than mountain-view ones, for a distance to the beach that is often the same.
Most hotels add a resort fee of $30-60 a night plus parking, not included in the advertised price. Prices are before tax: the state accommodation tax rose to 11% on 1 January 2026, and with the county tax and the general excise tax, add nearly 19% to the bill.
The Ala Moana district, just west of Waikīkī, offers a few cheaper hotels near the large shopping centre and Ala Moana beach. Kahala, east of Diamond Head, and Ko Olina, on the west coast, group together quieter resorts, away from the bustle.
On the North Shore, a single big hotel, at Turtle Bay, and a few holiday rentals and B&Bs let you sleep near the waves. Outside the tourist zones, Honolulu strictly regulates short-term rentals: check that a property is legally authorised before booking it.

What to eat in Oahu and Honolulu?
Plate lunches and poke, cubes of raw fish marinated in soy sauce and seaweed, are eaten everywhere, from supermarket counters to poke shops, for $12-20. Spam musubi, a slice of canned ham on rice wrapped in a sheet of seaweed, is sold in every convenience store and recalls the island's Japanese and military heritage.
Malasadas, holeless Portuguese doughnuts rolled in sugar, are enjoyed hot at Leonard's, open since 1952 in Kapahulu. The shave ice of Haleʻiwa and the garlic shrimp from the Kahuku food trucks make lunch on the North Shore.
Honolulu has the most varied food scene in the archipelago, fed by Japanese, Chinese, Korean, Filipino and Portuguese immigration: ramen, izakaya and dim sum in Chinatown and Mōʻiliʻili, Hawaiian regional cuisine in Kakaʻako, at $40-80 a dish in the best restaurants.
The luau, a feast with a pig cooked in an underground oven and Polynesian dancing, is booked at hotels or at the Polynesian Cultural Center for $150-250. Do your shopping at the supermarket or at the Kapiʻolani Community College farmers' market, at the foot of Diamond Head, on Saturday mornings, for fruit breakfasts.
Which kind of traveller is it for?
Oahu and Honolulu lend themselves to a relaxing, cultural and active trip. Whether you travel with family, as a couple or even solo, everyone finds their own pace. For accommodation, you will mostly find classic hotels, resorts and boutique hotels.
Entry requirements & practical info
UK, Australian and most EU passports need an ESTA, applied for online before departure, for stays of up to 90 days; a few EU countries sit outside the Visa Waiver Program and need a full visa. Canadians need neither, only a passport. Anyone who has been to Cuba since January 2021 cannot use an ESTA and must apply for a visa.
Rules change: before you leave, check your country's official travel advice.
Once there, to stay online without paying roaming charges, an Oahu and Honolulu eSIM activates in a few minutes and works as soon as you land (plans from €3.99). Remember suitable travel insurance too.
Frequently asked questions about Oahu and Honolulu
When is the best time to visit Oahu?
From April to June and in September-October, the weather is fine and warm, the sea is calm almost everywhere and prices are lower than at Christmas or in July. From November to March, there is more rain in short showers, the whales are around and giant waves break on the North Shore, to be watched from the beach.
How do you book Pearl Harbor?
The USS Arizona programme, with a film and a boat to the memorial, is free but must be booked on recreation.gov, with a $1 fee. Last-minute places exist but are limited. The battleship Missouri, the aviation museum and the submarine Bowfin are paid separately. Come without a bag, as they are not allowed.
Do you need to book Diamond Head and Hanauma Bay?
Yes, for non-residents. Diamond Head: a time slot on the state parks website, $5 per person and $10 for parking, about €4 and €9. Hanauma Bay: booking two days ahead at 7am Hawaii time, $25 per person, about €22, and closed on Mondays and Tuesdays.
Do you need to rent a car on Oahu?
Not for Waikīkī, Honolulu, Diamond Head and Pearl Harbor, which the bus serves. A car for one or two days makes the North Shore, the windward coast and the south-east coast much simpler. Avoid keeping it in Waikīkī, where parking costs $40-60 a night.
Can you swim on the North Shore?
In summer, from May to September, yes: the sea there is often as calm as a lake. In winter, no: the waves reach more than 10 metres and the currents sweep away even strong swimmers. That is the time to come and watch the surfers from the beach.
How many days do you need on Oahu?
Four days for the essentials, six to add the city and the windward coast without rushing. Most travellers spend three to five days there before moving on to Maui or Kauai, less than an hour's flight away.
Does the Hawaii Green Fee affect visitors?
Yes, indirectly: since 1 January 2026, the state accommodation tax has risen from 10.25% to 11%, to fund environmental protection and climate resilience. It is added automatically to the hotel bill, with nothing to pay separately.
