An Overview of Weather in Hawaii in September
Hawaii weather in September offers pleasant temperatures between 73 and 89 degrees Fahrenheit. Trade winds from the northeast somewhat calm the high humidity.
The rainy season doesn’t begin until November, so September rain tends to be mild-to-moderate with a higher chance on the northernmost islands.
The average rainfall statewide in September is less than four inches.
September falls within Hawaii’s hurricane season, but the islands only face a low risk. A hurricane has not made landfall in Hawaii since 1992, so don’t let hurricane season stop you from visiting.
The ocean reaches its warmest temperature in September, offering surfers, swimmers, sea kayakers, and canoeists the most pleasant water all year.
Six Central Pacific islands make up the U.S. state of Hawaii, all offering beautiful, hot weather during September.
The Big Island offers a variety of September weather patterns, depending on where you are. You may be surfing at sea level off the coast with a snow-capped volcano visible in the distance.
If you go on a hike into the hills or drive into the mountains, bring several clothing layers to stay comfortable as you hike higher up and the temperature drops.
The second-largest island in Hawaii, Maui, also offers a variety of weather depending on what part of the island you visit. Areas closer to the coast tend to be warmer while temperatures cool as you gain elevation.
The average temperatures on Maui in September reach lows of 60˚ F and highs of 77˚ F.
Oahu enjoys warm weather in September, averaging in the 80s. The wet season doesn’t begin until the middle of November, so September makes a great month to visit.
Kauai, also known as the Garden Island, experiences the same hot temperatures as the other islands. Temperatures average in the 80s, rarely sinking below 75˚ F.
If you’re visiting Molokai, September represents an excellent choice. With great weather averaging around 74˚ F, you’ll be able to enjoy everything the island has to offer with little chance of rain.
Lanai weather is the warmest in September, averaging between 81˚ and 84˚ F.
The island sees little to no rainfall during the summer months, so your trip won’t be spoiled by unwanted moisture.
Despite the beautiful September weather, crowds in Hawaii tend to decrease after Labor Day weekend.
The end of September is one of the least crowded times to visit Hawaii because summer break has ended for most school-aged kids.
Book your trip to Hawaii in September to enjoy the beaches and lovely Hawaii weather with fewer crowds.
You must consider several costs before traveling to Hawaii, including airfare, lodging, and the costs of activities like whale watching and snorkeling.
With summer demands decreasing, rates for visiting Hawaii in September tend to be lower.
Plane ticket prices tend to drop as U.S. school-aged children return to school in mid-August. Visitors can generally find more affordable tickets to Hawaii starting in July.
Hawaii hotel rates also decline, allowing for a cheaper visit than you would experience during peak season. Despite these lower hotel rates, you may find a more budget-friendly option by renting an Airbnb or staying at a hostel.
Food represents one of the most significant expenses during a trip. However, you can save some money by eating at food trucks instead of restaurants or opting for accommodations with a kitchen or kitchenette to prepare your own meals.
For many people, visiting Hawaii is about experiencing the unique, rich culture and learning about Hawaiian history.

September visitors love to swim in the oceans around Hawaii thanks to the warm water temperature.
If you go for a swim during your Hawaii trip, you must keep a few things in mind, especially if you’ve never swum in an ocean before.
Oceanic currents prove dangerously strong in some places around Hawaii. For example, we encourage only experienced swimmers and surfers to visit Lopa Beach on Lanai because rip currents can pull even strong swimmers out to sea.
Stay safe, swim in a group, and always watch your little ones carefully.
Swimmers in Hawaii must also make sure to use only reef-safe sunscreen to help protect the natural ecosystem.
Stand-up paddleboarding provides another great way to enjoy the ocean in Hawaii. Rent a paddleboard from a local shop, or join a tour to enjoy some unique views.

No matter which island you stay on, you’ll find amazing snorkeling opportunities.
Hawaii boasts dazzling marine life, beautiful reefs, and other underwater formations you must see if you enjoy snorkeling.
Book your reservation ahead of time to ensure you don’t miss out on your snorkeling adventure. Hawaii in September sees fewer tourists than in other months, but it’s still a good idea to reserve what you can early.
Are you scuba certified? Do you find the life below the ocean’s surface more interesting than the landscape above?
Diving tours take place all over Hawaii. Explore the underwater volcano at Molokini Crater, or take in the spectacular beauty at the Cathedrals of Lanai.

The only thing better than enjoying the stunning Hawaiian landscape is doing so on horseback. Hawaii offers many horseback riding tours on trails throughout the islands.
