By nine on an August morning in Wailea, the first snorkelers are already wading into the water in front of the big resorts, and the lava rock walls along the shoreline path feel warm. Out past the surf line, the island of Kahoolawe sits low on the horizon, and the smell of sunscreen and plumeria drifts across the lawns. This is Maui’s sunny, leeward side in the heart of summer, a good match for families on school break and anyone who wants beach days that rarely get interrupted.
What is the weather like in Wailea in August?
August in Wailea is hot, sunny and almost entirely dry, with warm days, mild nights and only the occasional passing shower.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| July | 87.1 | 69.1 | 1.9 | 79.4 |
| August | 87.3 | 69.2 | 1.4 | 80.0 |
| September | 86.8 | 69.1 | 2.7 | 80.4 |
Because Wailea lies on Maui’s leeward coast, sheltered from rain by Haleakala, the sky there remains clear so much of the time. Mornings are bright and gentle, with the trade winds keeping the air comfortable on the shoreline. By early afternoon the sun is strong enough that a hat and shade start to matter, and the lava rock paths hold the heat.
Rain, when it comes, is a brief shower that blows through and leaves the pavement steaming. Most of the island’s cloud and rain collects on the windward slopes and up the mountain, so a gray day in Hana does not mean a gray day on the Wailea beaches. Evenings are warm enough for dinner outside in a light shirt or sundress, and the days are long, with daylight lasting nearly thirteen hours in the middle of the month.
Pack for sun rather than weather: light cotton, a rash guard, sandals, and something thin for restaurants where the air conditioning runs cold. The ocean feels like a warm bath in the morning and stays that way through the afternoon.
Can you swim in Wailea in August?
Yes, you can take long swims and snorkel at an easy pace since the water is warm, and most of the time it feels cool and pleasant instead of chilly.
Wailea faces south and west, and in summer the big Pacific swells tend to arrive on the opposite shores, so the beaches here are often gentle. The go-to trio is Wailea Beach, Ulua Beach and Mokapu Beach, while snorkelers come to the rocky points between them hoping to spot reef fish and, on lucky days, a green sea turtle cruising by. Children and nervous swimmers often prefer the sheltered ends of these beaches in the morning, when the water is usually at its smoothest.
Conditions still change from day to day, and summer south swells can bring surprising waves to the shore break. Look at the beach signs and flags, listen to the lifeguards, and keep a respectful distance from turtles and the reef. Bring a snorkel mask, a rash guard and mineral sunscreen, the only kind Maui County allows to be sold or distributed without a prescription.
What to do in Wailea in August
August is a beach-first month in Wailea, and the rhythm of the days follows the sun: water in the morning, shade at midday, a walk or a boat trip when the light turns gold. Summer on Maui also means school-break energy, with families spreading out towels, kids on boogie boards and long picnic lunches under the kiawe trees.
The Wailea Beach Path
Stretching along the shoreline, the coastal walk connects the beaches and resorts, passing lava outcrops, manicured gardens and small coves. It is flat, easy and shaded in places, which makes it a pleasant stroll for almost anyone, from strollers to older travelers.
Set out at first light or close to dusk, when the air cools and copper hues spread across the sea. Along the way you pass the beaches in order, so you can decide where to stop for a swim, and you may spot turtles resting near the rocks or in the shallows. Bring water and a hat, because the path has more sun than shade at midday.
If you want a break, the shops and open-air restaurants near the resorts offer a cool place for shave ice, an acai bowl or a cold drink. Many travelers combine the path with a swim and a casual lunch, and the whole outing fills a relaxed morning.
Snorkeling and ocean outings
The warm water makes August one of the most comfortable months to get on a boat. Snorkel trips along the coast, and sunset sails, often leave from the nearby harbors, and outfitters rent masks, boards and kayaks for time on your own. The calm summer mornings are the best window for paddling, because the trade winds tend to freshen in the afternoon.
The famous snorkeling stop at Molokini crater is a popular choice for a boat day, and at the right hour the water around it is clear. Sea turtles are a common sight along this coast, but they are wild animals and protected, so watch them from a polite distance and never touch them. Humpback whales are winter visitors, so August is not the time for whale watching.
Golf, spas and long lunches
Wailea is known for its resort courses, which stretch across green slopes above the sea, and early tee times let you finish before the midday sun. When the heat peaks, the resort spas, pool decks and shaded restaurants are the natural place to be.
Dining here leans toward fresh fish, poke, grilled mahi-mahi, tropical fruit and cold drinks served with a view. Shave ice and local ice cream are the afternoon treats, and the open-air lounges fill up as the sun lowers. Evenings suit a long dinner outside, and some restaurants have live Hawaiian music on the terrace.
August is also a month for local events across Maui, from community festivals to craft fairs and farmers markets, and the dates shift from year to year. Ask at your hotel desk what is on during your week, because the island often has something happening within an easy drive.
For a change of scene, the road up to the cooler air of Upcountry Maui, with its lavender, farm stands and eucalyptus groves, is a favorite outing when you tire of the beach. Makena and its wide golden sands lie a short drive south, and make a good half-day when you want a different stretch of shore.
A two-day itinerary for Wailea in August
Day 1 is for settling in on the shoreline. Start early, with sunrise already well underway and the beach nearly empty, and walk the coastal path from one end to the other, stopping at Ulua and Wailea beaches for a swim and snorkel while the sea is at its softest. Have a late breakfast at a casual café, then retreat to the pool or a shaded lanai when the sun climbs.
In the afternoon, rent a paddleboard or kayak, or book a spa hour, and then head to a sunset dinner at an open-air restaurant. Sunset comes after a long day, so you can eat outside without rushing. If a shower passes, a spa or a shop-and-gallery walk keeps the day going.
Day 2 goes beyond the resorts. Take a morning boat trip for snorkeling, with a stop for turtles and reef fish, and be back by early afternoon for a late lunch of poke or fish tacos. Afterward, drive south to Makena for a quiet walk on the sand, or turn uphill toward Upcountry for cooler air and farm stands.
End with a relaxed dinner in town or at a resort terrace, with live music if there is any. When the weather turns gray or rainy, line up things to do inside, like a cooking class, a gallery visit or a leisurely lunch, and save the beach for the next morning that’s clear.
Is Wailea busy in August?
Yes, August is a busy month in Wailea, with summer family travel filling the resorts and beaches.
Schools on the mainland are still on break for much of the month, so families fill the pools, restaurants and boat trips, and the beaches are livelier by midmorning. Rooms and rental cars are in demand, and the best restaurant tables go quickly in the evening. As a habit, book flights, rooms and a car well ahead for the early and middle weeks, when families are traveling, and expect slightly more breathing room as schools start back later in the month.
Early mornings stay calm, even in busy weeks, so beach time before breakfast is a good strategy. Reserve dinner and boat trips in advance, and plan the popular sunrise or sunset outings first. Resort stays here also carry the state and county accommodations taxes, which is worth remembering when comparing rooms.
What to pack for Wailea in August
Think light, sun-smart and ready for the water, with one layer for cool restaurants and evenings.
- Mineral sunscreen, because Maui County allows only zinc oxide or titanium dioxide formulas to be sold without a prescription.
- A rash guard, for long snorkel sessions and strong midday sun.
- A wide-brimmed hat and sunglasses, since shade is scarce on the beach path.
- Water shoes, for rocky entries along the coves.
- A light layer, for air-conditioned dining rooms and breezy boat rides.
- A reusable water bottle, for hot walks and beach days.
Good to know before you go
August falls inside the Central Pacific hurricane season, which runs from June 1 to November 30. It does not happen often that Hawaii takes a direct strike, yet staying watchful of local forecasts while you are here and leaving some room in your plans is the smart approach. For getting around to beaches, restaurants, and Upcountry outings, nothing beats a rental car, and beach parking spots are gone by mid-morning.
| Fee | Amount | Who pays |
|---|---|---|
| State transient accommodations tax | 11% | Guests at resort stays in Wailea |
| Maui County transient accommodations tax | 3% | Guests at resort stays in Wailea |
Wailea in August vs July and September
Moving the trip to July changes very little in the weather or the sea. The air and water are almost the same, and the showers are just as rare, but July brings the peak of the summer break, with the busiest beaches and the toughest rental car market. If you want the classic summer vacation feel, July delivers it at full volume.
September is a touch warmer in the sea and a bit more likely to bring a shower, though the days still lean sunny. Families with school-age children have mostly gone home, so the beaches, restaurants and boat trips feel calmer, and it is easier to find a room or a table. The hurricane season is still running, so plans can stay flexible.
Choose July if the school calendar leaves no other option and you want the full summer atmosphere. Choose August for the reliably dry weather and the warm sea with a bit of the family bustle, and choose September for a quieter, slower stay with the same sunny feel.
Is August a good time to visit Wailea?
August works beautifully for a Wailea getaway, above all if you love the beach, you’re traveling with kids, or you simply want sunshine you can count on.
It suits travelers who plan their days around the water, from snorkelers and paddlers to people who simply want a lounge chair and a view. Travelers seeking quiet stretches of sand, the freedom to book at the last minute, or a chance to spot whales, which are part of the winter season, will find it a poorer fit. If you arrive on a busy week, set up your rental car, restaurant tables and boat trips first, then leave the rest of the days open.
What makes August special in Wailea is the combination of long, bright days, a sea that feels like silk, and the leeward shoreline at its sunniest, with the lava rock glowing at sunset and the whole coast humming with summer.
