If you’ve decided to go to Hawaii for your August vacation, beautiful natural landscapes and gorgeous beaches are not the only things that await you. There are hidden treasures in every corner of the state, from the quiet little towns in Maui to the busy Honolulu. In this concise guide, you’ll find everything you need to make the most of your trip.

August Weather in Hawaii

August in Hawaii is sunny and balmy with temperatures ranging from 75°F – 88°F. Each island has its own micro-climates depending on the direction of the trade winds. August tends to be the least humid month across all Hawaiian Islands, making it a pleasant time to visit.

Average Temperatures

The weather this month averages about 85°F on all islands. August is usually the driest month of the year, but hurricane season may bring some unexpected showers.

The further you go into the tropical rainforest climates in Hawaii, the more humid you’ll feel. But as we said, August is the least humid overall. It doesn’t rain much in August, just about 1.5 inches on the Big Island, 1 inch on Oahu, 2 inches on Kauai, and 0.5 inches on Maui, on average.

Water Temperatures

You can expect the water to be around 80°F, which means it stays comfortably warm for you to enjoy swimming, snorkeling, deep sea diving, and more.

Ocean Conditions

The ocean temperatures in August average at about 80°F, which is nearly 15 degrees warmer than off the west coast of continental America. The waves are usually larger on the south sides of the islands (like the Big Island) this time around as well.

Cost to Visit Hawaii in August

The hotel and flight prices at the beginning of August are typically higher than average and tend to drop towards the end of the month. If you want to travel to Hawaii on a budget, we’d recommend planning your trip in the last two weeks of August. This is because the school year in Hawaii starts in early August so the first week is still peak season and a bit more expensive. But it begins to quiet down as the month progresses.


The money you spend on plane tickets is likely to be the biggest portion of your budget. A round-trip from the west coast of the US can cost you $380 – $550. Direct flights from the east coast are more expensive at upwards of $900.

But hey, don’t worry. We have a few tried and tested tips for you to score a great deal on your flight:

  • Try to book your ticket about 100-120 days before your departure. Based on our personal experience and that of our readers, airlines generally release discounted seats around this time.
  • Booking your flight in two legs for the trip there and for the trip back (rather than round-trip or non-stop) can sometimes save you a significant amount of money.
  • Avoid weekend travel; Mondays and Tuesdays tend to have the lowest rates.
  • Use websites like Skyscanner, Priceline, and CheapOair for deals and cost comparisons between airlines. Hopper is also a good app that analyzes prices to predict the best dates for the lowest rates for certain airlines.

Hotel rates are high in the first week of August at around $300 per night. The prices eventually reduce to about $250 towards the end of the month. If you’re on a budget and traveling in a group, you can find a vacation rental through Vrbo at $120-$135 per night. Airbnb also has affordable lodging options.

Camping is another great option, but requires some planning ahead. There are several State and National Parks in Hawaii with basic to fully-equipped camping facilities. You’ll need to reserve a permit in advance though, which costs about $5 per person or $20 per campsite for 5 people.

Car Rental

It is fairly easy to rent a car on any of the islands. The price per day is usually upwards of $100. Enterprise, Dollar, Alamo, and Discount are some of the most popular companies for affordable rentals.

One trick many tourists don’t know about is bidding. You can bid for a car through websites like BetterBidding or Priceline. If you’re lucky, especially during the off-season, you could end up getting a car at a much cheaper rate.

Before you rent a car, be sure to verify what the fees include because in some islands the taxes are not included in the prices they advertise. Taxes can cost you up to 40% of the car rent amount. A surcharge of $25 per day for underage drivers (21-24 years old) also applies on all of the islands.

You may also want to check out the app Turo. This is like the Uber of car rentals and allows you to rent cars from private owners. We’ve had excellent results using this app.

Best Times to Book Your August Vacation

We recommend booking your flights, lodging, and car rental by the end of June or in the first week of July. This is the time when you’re likely to get most of the deals and discounts. However, if that’s not possible, booking at least 21-25 days in advance is an absolute must. Remember, Hawaii celebrates a lot of summer festivals and events in August. If you don’t book at least a month before your departure, you’ll have a hard time getting the room or car you want.

Is August Crowded in Hawaii?

The first two weeks definitely are. August is one of the peak months for tourists in Hawaii since the school is still out, making it an ideal time for family vacations. However, the last two weeks are not as crowded.

Events in August

There are many events in Hawaii scheduled during August, but they vary year by year.


The Ko Olina Resort on the leeward coast of Oahu holds the world-famous Paradise Cove Luau every evening at 5pm. This luau is a full-scale production with live local music, hula and Polynesian performances, an imu ceremony, traditional Hawaiian games, and of course, a scrumptious buffet. Tickets cost $85 – $170.
