Is Hawaii Nice in September: Weather Data

With average lows in the mid-70s and highs in the 80s, September in Hawaii offers ideal conditions for outdoor adventures. On average, the islands receive less than an inch of rain, so you can enjoy your vacation without worrying about unexpected showers.

While the weather can vary slightly from island to island, Hawaii in September is quite pleasant overall. To help you pack for your trip, let’s dive into the weather details and what you can expect during your stay.

Is Hawaii Rainy in September?

Like most tropical destinations, Hawaii experiences just two seasons: summer and winter. Generally, summer tends to be drier than winter. September is typically the second driest month of the year in Hawaii, with only a slight increase in rainfall compared to July.

Let’s take a closer look at four popular travel destinations in Hawaii and compare their rainfall in September:

In Poipu, Kauai, you can expect less than half an inch of rain for the entire month, making it unlikely to experience any showers. On the other hand, Honolulu, Oahu, typically receives the most rain, though it’s still relatively dry compared to other areas.

On average, these four locations received just 0.99 inches of rain throughout September. In comparison, July, the driest month, had a little less—about a tenth of an inch less, to be exact. While you probably wouldn’t notice the difference, July is technically the driest month of the year.

While you might still encounter an occasional light shower no matter when you visit, September is a fantastic time for a sunny vacation. The rain increases slightly in October as Hawaii transitions into its winter season. If you’re considering traveling a month later, check out how Hawaii in October stacks up!

Each of the Hawaiian Islands has a windward side and a leeward side, and the weather can vary significantly between the two due to the rainshadow effect.

Generally, the north and east sides of the islands receive more rainfall. So, if you visit towns like Kailua, Hilo, or Hana on the windward side, you can expect a bit more rain during your stay.

How Warm Is It in Hawaii in September?

September in Hawaii brings gorgeous weather and warm temperatures, acting as summer’s grand finale before the winter season kicks in. With an average high of 82.25°F, it’s the year’s warmest month. And don’t worry; the average low is just as pleasant at 75.75°F.

The Big Island is usually the warmest, and September is no exception. In Kailua-Kona, Hawaii, you can expect a nice high of 87°F. Maui and Kauai are a bit cooler, with highs around 80°F. But honestly, no matter which island you choose, you’ll enjoy beautiful weather throughout your stay.

While September’s warm temperatures are perfect for many, they may feel too hot for some. If you prefer cooler days, consider visiting in February or March, typically the coldest months of the year. However, remember that Hawaii’s tropical climate means that the average high temperature is still in the mid-70s, even in these cooler months.

Can You Swim in Hawaii in September?

Are water adventures on your Hawaii to-do list? Whether you’re planning to swim, surf, or snorkel, you might wonder what the water will be like.

In September, you’ll experience some of the warmest ocean temperatures of the year. The Pacific Ocean around Hawaii stays around 81°F throughout September and October. The coolest the water ever gets is during the winter months when it dips to about 76°F.

What Are the Ocean Conditions Like in September?

The Pacific Ocean can be fierce at any time of year, so it’s always important to check the lifeguard flags to assess the water conditions before heading in. 

Luckily, September doesn’t bring the huge swells that winter weather often brings, so the ocean is typically calmer than in December or January.

When is Hurricane Season in Hawaii?

Hawaii in September is beautiful, but it’s in the middle of hurricane season (June through November). While hurricanes are rare, it’s still a possibility. Since 1950, only five storms have caused major damage to the islands, so the risk is low.

Even so, it’s smart to be prepared. Have an emergency plan, let loved ones know your travel details, and follow local news on social media for updates. Jot down a few radio stations you can tune into in an emergency.
