March Weather Across the Islands
March sits at the tail end of Hawaii's wet season, and here's the thing — wet season in Hawaii isn't what you think. It means brief tropical showers that roll through and vanish. You'll get 30 minutes of rain, then sunshine for the rest of the day. Average rainfall drops noticeably from February, and by late March, you're basically in dry season territory.
Temperatures hover between 70-82°F across all islands. Trade winds keep things comfortable even at midday. Water temperature sits around 75°F — warm enough for extended snorkeling without a wetsuit. The UV index hits 10+, so sunscreen isn't optional. It's mandatory or you're spending Day 2 in your hotel room looking like a lobster.
- •Windward (east) sides of every island get more rain. Stay leeward for drier weather.
- •March sunsets hit around 6:30pm — later than winter months. More golden hour, more time outside.
- •Trade winds die down some days in March. When they do, it gets humid fast. Head to the beach.
Island-by-Island Breakdown
Oahu: 72-81°F, 3-4 inches of rain. Waikiki stays drier than the windward side. North Shore sees bigger swells early in March, tapering by month's end. Maui: 70-82°F, 2-3 inches of rain on the leeward side (Wailea/Kihei), up to 10 inches on the windward side (Hana). The rain difference between coasts is dramatic. Big Island: 71-81°F. Kona side is desert-dry, Hilo side gets serious rain. Two climates, one island. Kauai: 70-79°F, the wettest island overall but March is among the drier months. Na Pali Coast is stunning year-round.
What to Pack
Reef-safe sunscreen (SPF 50+) — Hawaii law bans oxybenzone and octinoxate. Light layers for elevation changes if you're heading up Haleakala or Mauna Kea. Water shoes for rocky shorelines. A packable rain jacket for those quick showers. Skip the umbrella — nobody uses them here and you'll look ridiculous.
Humpback Whale Season Finale
This is it. March is the last full month of humpback whale season in Hawaii. Roughly 10,000 humpbacks migrate from Alaska to Hawaiian waters each winter to breed, calve, and nurse. By April, they're heading back north. March catches the tail end — mothers with calves, juveniles practicing breaches, and males still competing for mates.
The whales are everywhere. You can spot them from shore on Maui, from hotel balconies in Kaanapali, from cliffside lookouts on the Big Island. But a boat tour gets you close enough to hear them breathe. That explosive exhale through the blowhole from 50 feet away — it rewires your brain.
- •Book whale watching tours for early morning. Calmer seas, better visibility, whales are more active.
- •Late March whale sightings drop off. First two weeks of March are your best bet.
- •Bring Dramamine if you get seasick. The Auau Channel is relatively calm, but boats are boats.
| Category | Price Range |
|---|---|
| Whale watch tour (Maui) | $50-65/person |
| Whale watch tour (Big Island) | $100-130/person |
| Shore watching | Free |
Maui: The Whale Capital
The Auau Channel between Maui and Lanai is the densest whale habitat in Hawaii. Shallow, warm, protected waters make it ideal for calving. Lahaina and Maalaea are the main departure points for boat tours. The Pacific Whale Foundation runs research-grade tours with marine naturalists on board — $50-65 per adult for a 2-hour trip.
For shore-based watching, Papawai Point (between Lahaina and Maalaea) is the best free lookout on the island. Bring binoculars. On a good March day, you'll see 15-20 breaches in an hour without spending a dime.
Big Island
Less crowded whale watching than Maui. Kona side boats head out into deep water where whales travel along the coast. Kohala Coast lookouts offer elevated shore-watching. Dan McSweeney's whale watch tours out of Honokohau Harbor are the gold standard — smaller boats, genuine expertise, $120 per person.
Oahu
Makapuu Point Lighthouse Trail is the best free whale watching on Oahu. Easy 2-mile round trip hike with panoramic ocean views. Whales are visible most days in March from the clifftop. Diamond Head summit works too, but the crowds are thicker.
Which Island Is Right for You
Four major islands, four completely different vibes. Picking wrong means spending your vacation wishing you were somewhere else. Here's the honest breakdown for March.
- •Two islands in 7 days works. Three islands in 7 days is a mistake — you'll spend more time at airports than on beaches.
- •Inter-island flights on Hawaiian Airlines and Southwest run $60-130 one-way. Book 3-4 weeks ahead for best fares.
- •If you only have 5 days, pick one island and go deep. Island hopping needs 7+ days minimum.
Oahu: The All-Rounder
Honolulu has the most flight options and the lowest fares. Waikiki is walkable, the food scene is world-class, and you can combine city energy with North Shore surf culture in a single day. Pearl Harbor, Diamond Head, and Hanauma Bay are all legitimate must-dos. Downside: it's the most touristy island by far. Waikiki can feel like a mall with a beach attached.
Best for: first-timers, food lovers, history buffs, people who want nightlife. March crowd level: moderate. Winter peak tourists are gone, spring breakers arrive late March.
Maui: The Greatest Hits
The most popular island for a reason. Road to Hana is one of the best drives in the world. Haleakala sunrise is transcendent. Whale watching is unmatched. Wailea and Kaanapali beaches are picture-perfect. The west side is dry and sunny, the east side is lush and dramatic.
Best for: couples, whale watchers, road trippers, snorkelers. Downside: resort prices are steep. A rental car is essential — Maui without a car is half the experience. March crowd level: moderate, thinning out from winter peak.
Big Island: The Adventure Island
Twice the size of all other Hawaiian islands combined. Active volcanoes, black sand beaches, snow-capped Mauna Kea, coffee farms, and manta ray night dives. Hawaii Volcanoes National Park is unlike anything else in the state. The Kona side is dry and resort-y; the Hilo side is rainy, raw, and beautiful.
Best for: adventure seekers, nature lovers, stargazers, people who want space. Downside: distances are real. Driving from Kona to Hilo takes 2.5 hours. You need a car and you'll spend time behind the wheel. March crowd level: lowest of the four major islands.
Kauai: The Wild Card
The oldest island. The most dramatic scenery. Na Pali Coast looks AI-generated but it's 5 million years of erosion. Waimea Canyon — the Grand Canyon of the Pacific — delivers insane red-and-green vistas. The pace is slower, the towns are smaller, the development is minimal by Hawaii standards.
Best for: hikers, photographers, honeymooners, introverts. Downside: fewer dining and nightlife options. Gets the most rain of any island. March crowd level: low. This is the quiet island and March keeps it that way.
North Shore Oahu: Surf, Shrimp, and Slow Living
The North Shore in March is a sweet spot. The massive 30-40 foot winter swells that close out beaches in January are calming down. March waves run 6-15 feet — still powerful enough to watch world-class surfers, but the beaches are open for swimming on calmer days. Pipeline, Sunset Beach, and Waimea Bay are all accessible.
The vibe up here is the anti-Waikiki. No high-rises, no luxury malls, no valet parking. Just surf shops, food trucks, and locals who moved here specifically to avoid all that. Haleiwa town has legitimate charm — art galleries, shave ice shops, and the kind of community feeling that tourist zones can't manufacture.
- •North Shore is 45-60 minutes from Waikiki with no traffic. With traffic, double it. Go early or stay late.
- •Check surf reports before swimming. March swells are smaller than winter but still powerful enough to be dangerous.
- •Sunset Beach lives up to its name. Be there at 6:15pm with a plate lunch.
| Category | Price Range |
|---|---|
| Shrimp plate | $14-16 |
| Surf lesson | $80-120 |
| Matsumoto's shave ice | $4-6 |
What to Do
Watch surfers at Pipeline (Ehukai Beach Park) — even in March, the skill level is jaw-dropping. Swim at Shark's Cove when conditions are calm — the tidepools are some of the best snorkeling on Oahu. Hike to Kaena Point for albatross nesting season (November through June). Jump off Waimea Bay rock if the lifeguards give the green light — 25 feet of pure adrenaline.
The Shrimp Truck Scene
Giovanni's Shrimp Truck started it all and the line is always long. Romy's is the local favorite — less hype, better shrimp, grown in their own aquaculture ponds right behind the truck. Fumi's is the underdog pick for garlic shrimp. A plate runs $14-16 with rice and macaroni salad. Eat all three and pick your champion.
Where to Eat
Hawaiian food is what happens when Japanese, Filipino, Chinese, Korean, Portuguese, Native Hawaiian, and American traditions collide on a volcanic rock in the middle of the Pacific. The result is one of the most unique food scenes in the country. Skip the resort restaurants charging $45 for a mediocre fish entree. The real food is at plate lunch counters, food trucks, and hole-in-the-wall spots.
| Category | Price Range |
|---|---|
| Plate lunch | $12-18 |
| Poke bowl | $14-20 |
| Shave ice | $4-7 |
| Nice dinner for two | $80-160 |
| Malasadas (half dozen) | $8-12 |
Oahu
Helena's Hawaiian Food in Kalihi for traditional lau lau, pipikaula short ribs, and poi — James Beard Award winner, cash only, no frills. Marukame Udon in Waikiki for fresh-pulled udon noodles — the line moves fast and a bowl is $6. Ono Seafood for poke that ruins all future poke for you. Side Street Inn for local-style pupus (appetizers) and the best fried rice on the island.
Leonard's Bakery for malasadas — Portuguese donuts rolled in sugar, filled with haupia (coconut) cream. Worth the 20-minute wait. Every time.
Maui
Tin Roof in Kahului — Chef Sheldon Simeon's casual spot. Garlic noodles and pork belly bowls that justify the trip to Maui on their own. Star Noodle in Lahaina for Asian-fusion small plates. Mama's Fish House in Paia is the splurge — $80-120 per person but the oceanfront setting and fresh-caught fish are legendary. Book 2-3 weeks ahead.
For cheap eats, Ululani's Hawaiian Shave Ice in Lahaina is the best shave ice in the state. Fight me.
Big Island
Kona Brewing Company for craft beer and pizza on the harbor. Sam Choy's Poke to the Max for the local take on raw fish done right. In Hilo, Cafe 100 for the original loco moco — hamburger patty over rice, topped with a fried egg and brown gravy. It's comfort food that doesn't apologize for itself. Punalu'u Bake Shop for malasadas and sweetbread near the black sand beach.
Kauai
The Dolphin in Hanalei for fresh fish in a riverside setting. Hamura Saimin Stand in Lihue — a noodle shop that's been open since 1952 and hasn't changed because it doesn't need to. Koloa Fish Market for poke by the pound. Small Town Coffee in Kapaa for the best espresso on the island.
Where to Stay
March is shoulder season — winter peak is fading and summer hasn't kicked in. Hotel rates drop 15-25% from January/February. You'll find actual availability at popular resorts without booking 6 months ahead. That said, Hawaii is never cheap. Budget accordingly.
| Category | Price Range |
|---|---|
| Oahu hotel | $180-350/night |
| Maui hotel | $220-500/night |
| Big Island hotel | $150-350/night |
| Kauai hotel | $180-400/night |
| Vacation rental (any island) | $150-300/night |
Oahu ($180-350/night)
Waikiki for convenience — beach, restaurants, nightlife all walkable. The Outrigger and Hyatt Regency are solid mid-range picks. For budget, look at hotels on Kuhio Avenue (one block from the beach, significantly cheaper than oceanfront). North Shore vacation rentals run $150-250/night and put you in a completely different Hawaii.
Maui ($220-500/night)
Wailea for luxury resorts and guaranteed sunshine. Kaanapali for the classic beach strip — hotels line 3 miles of golden sand. Kihei for condos and vacation rentals at lower prices — still sunny, still beachy, less polished. Paia for boutique stays near the start of the Road to Hana. Lahaina for central location and walkable dining.
Big Island ($150-350/night)
Kona Coast for resorts and dry weather. Waikoloa for family-friendly resort complexes with pools and golf. Volcano Village for a unique stay near Hawaii Volcanoes National Park — cool temperatures, rainforest setting, fireside vibes. Hilo for budget hotels and an authentic local town that tourists skip.
Kauai ($180-400/night)
Poipu for sunny south shore beaches and resort access. Princeville for north shore luxury with Na Pali Coast views. Kapaa for mid-range options and a central location. Hanalei Bay is gorgeous but accommodation is limited — book early if that's your target.
Budget Breakdown
Hawaii is expensive. No getting around it. Everything is shipped in — groceries cost 30-60% more than the mainland. But March shoulder-season pricing takes the edge off. Here's a realistic 7-day budget for one person.
- •Grocery stores beat restaurants for breakfast and lunch. Foodland and Costco are your friends.
- •Free activities add up fast: beach days, hiking, snorkeling, whale watching from shore, sunsets.
- •Skip resort parking fees ($30-40/night) by staying at a vacation rental with free parking.

Sample 8-Day Two-Island Itinerary: Oahu + Maui
This itinerary covers the two most popular islands without feeling rushed. Three days on Oahu, four on Maui, with a buffer day for flexibility. Adjust based on your pace.
Day 1: Arrive Oahu
Land at HNL. Check into Waikiki hotel. Afternoon swim at Waikiki Beach — the water is warm enough to stay in for hours. Sunset drinks at Duke's on the Beach. Walk Kalakaua Avenue for dinner — skip the chain restaurants, find a plate lunch spot on a side street.
Day 2: Pearl Harbor + North Shore
Morning at Pearl Harbor National Memorial (free, but reserve timed tickets online weeks in advance). USS Arizona Memorial is powerful and sobering. Drive to North Shore after lunch — Giovanni's or Romy's for shrimp. Watch surfers at Pipeline. Shave ice at Matsumoto's. Sunset at Sunset Beach.
Day 3: Diamond Head + Local Food
Early morning hike up Diamond Head ($5 entry, book parking reservation). Done in 90 minutes. Leonard's Bakery for malasadas. Snorkeling at Hanauma Bay ($25 entry, reservations required — they limit daily visitors). Afternoon at Ono Seafood for poke. Evening in Chinatown for cocktails and live music.
Day 4: Fly to Maui
Morning flight HNL to OGG (30 minutes, $60-130). Pick up rental car. Drive to your hotel — Kihei or Wailea for sun, Lahaina for location. Afternoon at the beach. Sunset at Kaanapali — the daily cliff diving ceremony at Black Rock is free entertainment.
Day 5: Whale Watching + West Maui
Morning whale watching tour from Lahaina or Maalaea ($50-65). March whales are active — expect breaches, tail slaps, and spy hops. Afternoon at Napili Bay for snorkeling with sea turtles. Dinner at Star Noodle. Walk Lahaina's Front Street as the sun goes down.
Day 6: Road to Hana
Leave by 7am. 620 curves, 59 bridges, countless waterfalls. Key stops: Twin Falls (easy first waterfall), Wai'anapanapa State Park (black sand beach, reserve entry permit), Hana town for lunch. If you're up for it, continue past Hana to Pipiwai Trail and the 400-foot Waimoku Falls. Return the same way or loop around the south — the backside road is unpaved and most rental car companies say no, but locals do it daily.
Day 7: Haleakala + Upcountry
3am wake-up for Haleakala sunrise ($1 entry fee, but sunrise reservations are required 60 days ahead at recreation.gov — set a reminder). Watch the sun rise above the clouds at 10,023 feet. It's cold up there (30-40°F) — bring every layer you packed. After, explore Upcountry Maui: Makawao town, Surfing Goat Dairy, Ali'i Kula Lavender Farm. Afternoon at your favorite beach.
Day 8: Final Beach Day + Depart
No agenda. Sleep in. Hit a beach you missed — Makena (Big Beach) for body surfing, Kapalua Bay for calm snorkeling. Tin Roof for a farewell lunch. Afternoon flight from OGG.
