Honolulu is the capital of Hawaii, on the south shore of Oahu. Waikiki Beach, the Diamond Head crater, and rainforest trails up Manoa are all within a short drive of downtown. The climate is warm and sunny most of the year, so lightweight clothing covers most of your trip. A few specific items make the rest of it easier.

The dress code is casual nearly everywhere. Leave the formal wear at home. Even upscale restaurants rarely ask for more than resort casual. Pack swim gear, real sun protection, and clothes you can layer for air-conditioned rooms and breezy evenings. Hawaii bans the sale of sunscreen with oxybenzone or octinoxate, so the reef-safe mineral brands are what you will find in stores there. Bring your own or buy it once you land.

Most days you will be snorkeling at Hanauma Bay, climbing to Manoa Falls, or walking Pearl Harbor, so pack for sun, surf, and a quick rain shower that clears as fast as it came.

Temperature: 80-90°F°FAPR 26Warm and sunny, with steady trade winds keeping the humidity down. Rain is light and the skies stay mostly clear. The UV index runs extreme at 11+, so cover up. Water sits around 77-82°F, good for swimming and snorkeling all day.

Packing Tips for Honolulu, Hawaii

  1. 1Hawaii bans the sale of sunscreen with oxybenzone or octinoxate. Mineral sunscreen with zinc oxide or titanium dioxide is what stores carry, so bring it or buy it there.
  2. 2Pack a lightweight rain jacket or poncho. Brief showers blow through any month, more often on the windward side of the island.
  3. 3Leave heavy jackets and boots at home. The trade winds keep Honolulu warm through the year.
  4. 4Bring a reusable water bottle. The tap water is safe to drink and you will go through a lot of it in the heat.
  5. 5Carry a dry bag or waterproof phone pouch for beach days and anything near the water.
  6. 6Wear your bulkiest shoes on the plane to save luggage space. Hiking shoes or sneakers work best for this.
  7. 7Pack light, breathable fabrics like cotton and linen. Moisture-wicking synthetics also hold up in the humidity.
  8. 8Bring a small daypack for hikes and day trips. You will use it almost every day.

Frequently asked questions

Do I really need reef-safe sunscreen in Hawaii?
Effectively, yes. Hawaii law bans the sale and distribution of sunscreen with oxybenzone or octinoxate, so the brands you find in stores there are the mineral kind, zinc oxide or titanium dioxide. The law targets sellers, not what you wear, so you will not be fined for bringing your own. The reefs are the real reason to use it. Buy reef-safe before you go or pick it up in Honolulu.
What should I wear to dinner in Honolulu?
Honolulu has a very casual dress code. Most restaurants, including upscale ones, accept resort casual attire: a clean polo or aloha shirt, sundress, nice shorts, or lightweight pants with sandals. Only a handful of fine dining spots require closed-toe shoes or collared shirts.
Is it worth bringing my own snorkel gear?
If you plan to snorkel more than once, bringing your own well-fitting mask is worth it. Rental masks often leak and can ruin the experience. Fins and snorkels are easy to rent at shops near Hanauma Bay and Waikiki. A good mask is the single most important piece of snorkel gear.
How much rain should I expect during the wet season?
Honolulu's wet season (November through March) brings showers that are usually brief and localized. The south shore, including Waikiki, gets less rain than the windward side. You will still see plenty of sun between the showers. A packable rain jacket is all you need.
Do I need hiking boots for Diamond Head?
Diamond Head is short and mostly paved with stairs, so sneakers or trail runners are fine in dry conditions. For Manoa Falls, Koko Head, or any ridge trail, wear hiking shoes with real grip. Those trails get steep, uneven, and slick with mud after rain.
Can I use my cell phone and credit cards everywhere in Honolulu?
Cell coverage is solid and most businesses take cards. Some food trucks, farmers markets, and small shops are cash-only, so carry at least $50 in small bills. Your regular US phone plan works the same as on the mainland, since Hawaii is a US state.
Should I pack differently for the North Shore vs Waikiki?
The North Shore is more rural and outdoorsy compared to Waikiki. Bring comfortable walking shoes, a sun hat, and plenty of sunscreen. In winter, the North Shore has massive surf, so bring binoculars if you want to watch from the beach. Waikiki is more urban, and you might want a nicer outfit for restaurants and nightlife.
What is the UV index like in Honolulu?
The UV index in Honolulu regularly reaches 11 or higher, which is classified as extreme. You can sunburn in as little as 15 minutes without protection. Apply SPF 50+ sunscreen every two hours, wear a wide-brim hat, and seek shade during peak hours (10 AM to 2 PM). A UPF-rated sun shirt provides reliable protection in the water.
