What to Do in Oahu When it Rains

There's no shortage of local Oahu attractions, from the best nightlife to endless beach activities, dining, and shopping. It's the lively epicenter of paradise with its dynamic culture. Over 500,000 active travelers flock to this famous island monthly. With exotic scenery, tropical breezes, and edgy volcano landscapes, this “Gathering Place” hypnotizes visitors with its magnificent, striking beauty and wonder.

When you visit the Ala Moana Center, Honolulu's sizeable open-air shopping mall with more than 350 shops and restaurants, souvenir stores, and food vendors, you can also uncover the historic Aloha Tower and observation deck for beautiful Harbor views.

Most importantly, let's not forget Oahu is the site of Pearl Harbor, the deadly location where the Japanese first attacked the U.S. in WWII.

Oahu Attractions

Battleship Missouri Memorial Mighty Mo Pass

This pass to the Battleship Missouri Memorial (the last U.S. Battleship ever built 'aka Mighty Mo') is a must-see attraction. Visitors can view the ship's decks and quarters and learn historical accounts of the Japanese surrender. Your pass includes a 35-minute guided, audio, and self-guided tour.

Consequently, children under ten are not permitted on the Heart of the Missouri Tour. However, if you'd like to explore Pearl Harbor’s grandeur, keep reading!

Passport to Pearl Harbor

The Passport to Pearl Harbor includes four destinations in one historic location. You might be hoping for a rainy day for this Pearl Harbor experience, as there is so much to see and do.

Using the passport by 10 am is recommended to see all the powerful sites, including the Battleship Missouri Memorial & Pearl Harbor Aviation Museum on Ford Island, a secured military base.

Photo Alert: Cameras are allowed at Pearl Harbor, and you can take photos everywhere, EXCEPT on the Admiral Clarey Bridge to Ford Island.

Bishop Museum

The incredible Bishop Museum and all of its signature galleries will astonish you with Hawaiian art, traditions, and Polynesian culture. Founded in 1889, the Bishop Museum is the largest Hawaiian museum. Designated the Hawaii State Museum of Natural and Cultural History, this institute of science is located in the historic Kalihi district of Honolulu.

Its research projects, educational programs, and consulting services are known worldwide. The museum is open daily from 9 am to 5 pm and is loaded with top-tier exhibits and more than 24 million natural history specimens.

Pro Tip: Oahu’s wettest period is during winter, from mid-November through late March. Considering the weather, crowds, and accommodations, the best time to visit is early April, May, September, and October.

Polynesian Cultural Center

Just under 75 minutes from Honolulu, the Polynesian Cultural Center features extraordinary attractions, including eight simulated tropical villages, IMAX shows, canoe rides, and exhibits. Guests can also experience the renowned Ali'i Luau, one of Oahu's best and most original luaus.

Visitors can mingle with the Pacific natives and learn about island culture. Get a temporary tattoo, enjoy the live music, and learn to dance one of the hip-shaking Tahiti island dances.

Pro Tip: You can still sunburn on a cloudy day in Hawaii, especially if you're in and around water. Slap some good U.V. protection on and catch an H.I. island wave.

Queen Emma Summer Palace

The Summer Palace served as a retreat for King Kamehameha IV's reigning sovereigns and his wife, Queen Emma. The secluded mountain home in the cool Nuuanu Valley allowed the royal family to escape the oppressive Honolulu heat. Today the Palace is a historic landmark, museum, and preserved tourist attraction by the Daughters of Hawaii.

The Shangri-La Museum
