Visiting Maui In September: Everything You Need To Know
In this guide you’ll discover everything you need to know about visiting Maui in September — weather, travel demand, average prices, and the best things to do while you’re there.
Here’s everything you need to know about visiting Maui in September — from the weather and prices to how busy it gets and the best things to do.
Maui Weather in September
Heading into September in Maui means you’re still enjoying summer‑level warmth, but with the benefit of slightly cooler temps and fewer crowds.
- On the low‑elevation coastal areas, daytime highs sit around 87 °F (about 30.5 °C), rarely dropping below 84 °F.
- Nighttime lows average around 72 °F (about 22 °C) in many areas.
- Rainfall remains fairly low; the island tends toward its drier season, with many clear, sunny days.
- Because the ocean temperature is still warm (often around the high 70s °F / mid‑20s °C), swimming, snorkeling and beach time are very comfortable.
- One caveat: September is still within the range of Hawaii’s tropical weather season, so while direct storms are rare, it’s wise to stay aware of the weather and surf conditions.

Sunrise & Sunset in September
Knowing how much daylight you’ll have helps plan beach time, drives and relaxing evenings.
- At the beginning of September, you’ll have about 13 hours of daylight, and by the end of the month slightly less—still plenty of time to enjoy outdoor activities.
- Sunrise times will be early (around 5:50 a.m. local time) and sunset around 6:55‑7:10 p.m. early in the month. These times will shift slightly as the month progresses.
- These daylight hours give you flexibility to hit the beach early, explore mid‑day and still enjoy dinner or a sunset stroll without rushing.
September Is Shoulder Season in Maui
Here’s how tourist demand, pricing and crowd levels tend to behave in September—and what that means for your trip.
- September is typically a shoulder season on Maui—summer vacation demand is easing, but weather remains excellent.
- For flights and accommodations: Because you’re past the peak summer rush, you may find better rates or more availability compared with July/August.
- For crowds: Expect fewer tourists than during the top summer months. Popular beaches, tours and resorts will still be active—but there’s more space and a more relaxed feel.
- Booking tip: If you go in September, especially early or mid‑month, it can be a sweet spot for value + quality. If you travel later in the month, keep an eye on any school‑travel windows or event weeks.
- One thing to watch: While storms are rare, being in the tropical season means you should monitor weather conditions and purchase refundable reservations where practical.
Best Things To Do in Maui in September
September gives you a sweet combination of warm weather, long daylight and fewer crowds—making it a great time for classic Maui experiences.
• Snorkel at Molokini Crater
September still brings calm morning seas, so visibility is fantastic around Molokini. Water temps are warm, crowds are lighter, and you get those classic Maui reef colors without peak-season demand.
• Relax on Kāʻanapali Beach
September is one of the best months for beach days here — warm weather, fewer families, and plenty of room to spread out. The sunsets along this stretch in fall are unreal, especially if you’re staying nearby.
• Drive the Road to Hāna
With summer crowds gone, September is a great time to take on this drive. Waterfalls are usually flowing, the jungle feels refreshed after the wetter season begins, and you won’t feel rushed at the pullouts.
• Explore Haleakalā National Park for Sunrise
Cooler mornings make the sunrise trek feel a bit more comfortable this time of year. Setember also avoids the heavy summer demand, so getting a reservation is usually easier.
• Snorkel with sea turtles
Turtle sightings are common year-round, and September's warm water keeps them close to shore. Early mornings here are peaceful and perfect for an easy swim.
• Explore ʻĪao Valley State Monument
September brings more misty mornings and green landscapes, which make the valley feel especially dramatic. Trails are short but scenic — an easy way to experience Maui’s interior.
• Take a sunset sail
Fall sunsets hit differently — lots of gold and deep reds. September evenings are warm, so sailing at golden hour is one of the most relaxing things you can do.
• Visit Upcountry Maui — Kula & Makawao
Fall is a great time to wander farms, sip locally grown coffee, or stop by lavender fields. Temperatures are cooler in Upcountry, giving you a nice break from the coastal heat.
• Check out Maui’s fall festivals
September on Maui lines up with the Festivals of Aloha — a weeklong celebration of Hawaiian culture that includes events like the Hāna Parade. You’ll also find Maui Friday Town Parties happening in spots like Wailuku, Lahaina, and Kihei, plus fun community gatherings such as the Maui Made Festival and Lahaina’s Art Night.
