Honolulu Travel Guide 2026: Waikīkī, Diamond Head, Oʻahu

Honolulu is the easiest way into Hawaii: the largest choice of hotels on Oʻahu, and a bus network that reaches most of what first-time visitors want to see on Oʻahu. It is warm in every month, so the real planning is about which side of the island you want in which season, and about three sights that now need tickets booked in advance. Fees and times below were checked on 9 October 2026.

When is the best time to visit Honolulu?

Any month works for warmth. The difference is rain on the south shore and surf on the north shore.

Figures are NOAA’s 1991-2020 climate normals for the Honolulu International Airport station. For winter sun, Honolulu runs about 2°C warmer than Miami in January: compare it with Miami, or see where else is warm in our where to go in December and where to go in January guides.

Winter is the North Shore’s season. The Hawaii Tourism Authority puts the best big-wave surfing from November through February, when waves can reach thirty feet or more at Waimea Bay, ʻEhukai Beach (the Banzai Pipeline) and Sunset Beach. That is a spectacle to watch from the sand, not a swim: those breaks are for experts only.

Where should you stay in Honolulu?

Most visitors sleep in Waikīkī, and for a first trip that is the right call.

First trip and you want the beach without a car? Book in Waikīkī, ideally close to Kalākaua Avenue so the beach and the W Line are both a short walk away. On a tighter budget, look at Ala Moana and Kakaʻako and ride in. Compare Honolulu hotel prices by area .

How do you get to and around Honolulu?

Honolulu’s airport is Daniel K. Inouye International Airport. From the mainland, our cheap flights from San Francisco to Honolulu guide covers fares and the best months to fly.

What should you not miss in Honolulu?

Diamond Head is open daily from 6 a.m. to 6 p.m. The trail is 0.8 mile from the trailhead to the summit; allow 1.5 to 2 hours. The last reservation is 4 p.m., you must arrive within the first 30 minutes of your slot, and there are no refunds for late arrivals. Go early, before the heat.

Hanauma Bay is Oʻahu’s best-known snorkelling bay, run by the City and County of Honolulu as a nature preserve. It is open Wednesday to Sunday, with entry from 6:45 a.m. to 1:30 p.m., and everyone must leave by 4 p.m. It closes on 25 December and 1 January. Every visitor watches a short educational video before going down to the water. About a quarter of access is kept for walk-ins, and your whole party has to be present to get one.

Pearl Harbor National Memorial has free museums and grounds, open daily from 7 a.m. to 5 p.m. except Thanksgiving, Christmas and New Year’s Day. The USS Arizona Memorial program takes about 45 minutes, the first starts at 8 a.m. and the last boat leaves at 3:30 p.m. Arrive an hour before your time. If the 56-day window sold out, more tickets are released the day before at 3 p.m. HST, and limited standby tickets exist. Bags are not allowed, including purses and camera bags; storage near the entrance costs a small fee.

What day trips can you take from Honolulu?

• The North Shore. Roughly an hour’s drive from Waikīkī. Haleʻiwa is the surf town, with food trucks, shops and plenty of shave ice; in winter, watch the surf at Waimea Bay, Pipeline and Sunset Beach, and always heed the warning signs.
• Hanauma Bay and the southeast coast. Combine an early snorkel slot with the coastal drive east of Diamond Head.
• Another island. Inter-island flights to Maui, Kauaʻi and the Island of Hawaiʻi leave from the same airport; see our San Francisco to Honolulu flight guide for how island-hopping fares stack up.

What goes wrong on a Honolulu trip?

• Turning up at Diamond Head without a booking. Non-residents without a reservation are turned away.
• Arriving at Hanauma Bay on a Monday or Tuesday. It is closed both days, and tickets only open two days ahead.
• Bringing a bag to Pearl Harbor. Leave it at the hotel or pay for storage.
• Swimming on the North Shore in winter. Big-wave days are for watching; the calm-water swims are on the south shore.
• Boarding the bus with a big suitcase. The size rule is enforced; plan a taxi for oversized luggage.
• Using a copycat ESTA site. Visa Waiver Program travellers need an approved ESTA, which costs $40.27 on the official esta.cbp.dhs.gov site. Our USA guide explains entry, tax and tipping.

How many days do you need in Honolulu?

Four to five days covers it: a Waikīkī beach day, Diamond Head, a morning at Hanauma Bay, a half day at Pearl Harbor and a full day on the North Shore. Add two or three days to fly on to a second island. Coming from the West Coast? Pair it with a few days in Los Angeles, the other winter-sun city on our USA list.

Frequently Asked Questions

What is the best time to visit Honolulu?

Honolulu is warm all year, so the best time depends on what you want. NOAA’s 1991-2020 normals for Honolulu International Airport show average highs of about 27 to 28°C from December to March and about 30 to 32°C from June to September. April to September is the driest stretch, with about 13 to 22 mm of rain a month, while November to March brings about 47 to 60 mm and the North Shore’s big-wave surf season.

Is Honolulu warm enough for the beach in winter?

Yes. Honolulu International Airport averages highs of about 27.7°C in December, 26.9°C in January and 26.9°C in February, with lows around 19 to 21°C, according to NOAA. Winter is also the rainiest season, but even then the airport averages only about 47 to 60 mm of rain a month.

Where should I stay in Honolulu for the first time?

Stay in Waikīkī for a first trip: the beach, most hotels, Kapiʻolani Park and the TheBus W Line from the airport are all there, at the price of crowds and the highest room rates. Ala Moana and Kakaʻako are close by and often cheaper. Ko Olina and the North Shore are quieter, but you will want a car.

Do I need a reservation for Diamond Head?

Yes, if you are not a Hawaii resident. Hawaii State Parks requires an entry reservation, which you can make up to 30 days in advance, and turns away visitors without one. Non-residents pay $5 per person and $10 per vehicle for parking. The trail is 0.8 mile to the summit; allow 1.5 to 2 hours.

How do I book Hanauma Bay and Pearl Harbor?

Hanauma Bay tickets ($25 for visitors aged 13 and over) are released online two days in advance at 7 a.m. Hawaii Standard Time, and the preserve is closed on Mondays and Tuesdays. Pearl Harbor National Memorial is free, but USS Arizona Memorial program tickets on Recreation.gov carry a $1 fee and open 56 days ahead, with more released the day before at 3 p.m.

How many days do you need in Honolulu?

Four to five days covers Honolulu well: a Waikīkī beach day, the Diamond Head hike, a morning at Hanauma Bay, a half day at Pearl Harbor and a full day on the North Shore, which is about an hour’s drive from Waikīkī. Add days if you want to hop to another island.

Start planning your Honolulu trip

If a package already covers your hotel, skip this part. If you are booking flights and a room separately, compare a few dates in April, May or September first, when the weather is dry and the holiday-week prices have passed.
