Hawaii Travel FAQ

No, if you're a U.S. citizen — Hawaiʻi is a U.S. state. Bring a driver's license. International visitors need a passport + ESTA/visa (same as visiting any U.S. state).

U.S. dollar. ATMs everywhere. Most places take credit cards; some food trucks + farmers markets are cash-only.

English is the everyday language. Hawaiian (ʻōlelo Hawaiʻi) is the second official state language and is taught in schools. You'll see Hawaiian words on signs, in place names, and in greetings (aloha, mahalo).

Same as mainland: 18-22% at restaurants, $1-2 per drink at bars, $2-5 per bag for porters, 15-20% for tour guides. Some tour operators include gratuity in the price.

Hawaii Standard Time (HST). UTC-10. Hawaiʻi does NOT observe Daylight Saving — so the gap from mainland is 2 hours (PT) in winter and 3 hours (PT) in summer.

Very. Violent crime is low. The biggest tourist risks are ocean conditions (rip currents, big surf), sunburn, dehydration, hiking flash floods, and rental-car break-ins (don't leave valuables visible).

Yes — reef sharks (4-6 ft, shy, harmless) are common. Tiger shark + Galapagos shark incidents are rare (a few per year statewide). Murky water + dawn/dusk are when to be cautious.

No snakes, no bears, no big cats. The most dangerous animals are mosquitoes (occasional dengue outbreaks), centipedes (painful bite but not fatal), and wild boar (very rare encounters).

Hurricane season is June-November. Big hurricanes hit Hawaiʻi rarely (~once per decade). Most years the storms weaken before landfall. Check weather.gov before your trip.

April-May and September-October are sweet spots: less rain, fewer tourists, lower hotel prices. December is busiest (whales + winter break). Summer is hot but mostly dry.

December through April. Peak January-February. Best on Maui (ʻAuʻau Channel).

Windward (northeast) sides are wet year-round; rainier November-March. Leeward (southwest) sides — Waikīkī, Kona, Wailea — get most of the sun.

Mid-April to early June, and September-early December. Avoid Thanksgiving week, December 20-January 5, and spring break (variable but March).

Popular ones yes — lūʻau, manta ray dives, helicopter tours, Diamond Head reservation, Hanauma Bay reservation — book 4-8 weeks ahead. Beaches and most hikes are free + drop-in.

Very. Calm beaches (Kailua, Ko Olina), aquariums (Maui Ocean Center, Waikīkī Aquarium), zoo (Honolulu), pineapple maze (Dole Plantation), Polynesian Cultural Center.

Sometimes. Kīlauea (Big Island) erupts in cycles — check the USGS Hawaiian Volcano Observatory for current status. When active, Volcanoes National Park is the best free vantage.

Every island has multiple great spots. See our snorkel guide → /blog/hawaii-snorkel-guide

On Oʻahu — optional (great bus network, Uber). On other islands — strongly recommended. Book early; rates skyrocket close to dates.

No. Each island is separate. Inter-island flights are short (~30 min) and frequent. Hawaiian Airlines + Southwest serve all major islands.

Pricey ($35-50/day at hotels). Free street parking exists with reading the signs. Most places require a meter ($1-3/hr). Parking lots near the beach charge $10-20/day.

Strong in cities + tourist areas. Patchy on north shores, valleys, and remote areas (Hana Road on Maui, Kalalau Trail on Kauaʻi). Verizon + AT&T have the best Hawaiʻi coverage.

Learn 5 words: aloha, mahalo (thank you), ʻohana (family), kuleana (responsibility), mālama (to care for). Don't take rocks or lava (it's both illegal and bad luck). Ask before photographing kūpuna (elders) or ceremonial events.

A garland — usually flowers, sometimes shells, leaves, or kukui nuts — given as a gesture of aloha. Accept with grace; never refuse. Wear over the head, draped onto both shoulders.

Hula is the dance. Lūʻau is the feast (which often includes hula performances). Both are part of Hawaiian cultural heritage; pre-missionary hula was once banned by Westerners.

Hawaiian custom: shoes off when entering a home (or many restaurants + shops with 'shoes off' signs). It dates to Asian + Pacific Islander cultural roots.

Volcanic smog from Kīlauea (Big Island). Most days the trades blow it out to sea. When kona winds reverse the flow, the haze settles on Kona + south Maui + Oʻahu. See our vog guide → /blog/what-is-vog-hawaii-air-quality

Sunscreen without oxybenzone or octinoxate. Hawaiʻi banned those chemicals because they damage coral reefs. Use mineral (zinc oxide) sunscreens — every drugstore sells them now.

Hawaiʻi beaches can be deadly — high surf, rip currents, shore breaks, jellyfish swarms. Yellow/red flags mean caution. Never turn your back on the ocean. When in doubt, ask a lifeguard.
