What to Wear in Maui in October
Maui in October: 32°C / 90°F afternoons, 21°C / 70°F nights, and the last dry month before the rains and the whales.
- Hibiscus-red long-sleeve surf suit — Maui County bans non-mineral sunscreen, so cover your arms instead
- Pale olive long-sleeve shirt — long-sleeved shirts are on the county's own cover-up list
- White slim jeans — Kula averages 58.2°F at dawn in October
- Olive canvas hat with a chin cord — the trade wind lifts an uncorded brim
- Tan fisherman sandals — a woven toe cage on lava-rock shorelines
- Hibiscus-red linen midi — Kahului's 70.1°F nights are the last above 70°F until June
- Non-mineral sunscreen — Maui County bans its use as well as its sale
- White jeans on the Road to Hāna — NOAA gives Hāna 6.88 inches of October rain
- Lahaina's fenced-off lots — the county asks visitors to stay out
- Sandals at the Haleakalā summit — the park lists sturdy shoes for the rim
Pack for sun, not wind. NOAA NCEI's normals for Kahului Airport give October 31.5°C by day and 70.1°F at night, with 21mm of rain over six or seven days, and November more than doubles that total. Upcountry stays mild: Kula averages 74.1°F by day and 58.2°F at dawn. NOAA's whale sanctuary puts humpback season at November through April, so October mornings belong to swimming and snorkeling. That means hours in the water under a high sun, and Maui County bans the sale and use of non-mineral sunscreen; its advice is to cover up with hats, long-sleeved shirts, sunglasses and a rash guard in the water. Build the week on long sleeves, a corded brim and one red dress for dinner.
October is Maui's last summer month. The rain has not started, the whales are a few weeks out, and the only thing to plan around is the sun.
The capsule
01Hibiscus-red long-sleeve surf suit, front zipMaui County's Ordinance 5306 bans the use of non-mineral sunscreen, and the county's own advice is to cover up in the water with a rash guard or a wetsuit. A long-sleeve one-piece does both jobs: arms, back and shoulders covered for a two-hour snorkel with nothing to reapply. The front zip gets it on over wet skin, and hibiscus red is easy to spot from the beach.
02Pale olive long-sleeve cotton shirtWear it open over the surf suit between swims, buttoned and tucked into the jeans for lunch Upcountry, and loose over the red dress after dark. Long-sleeved shirts are on Maui County's short list of cover-ups, cotton breathes at 31.5°C, and pale olive shows less sand and sunscreen than white.
03Warm-white slim straight jeansUpcountry runs on different numbers. NOAA's normals for Kula Branch Station, 3,100 feet up the slope of Haleakalā, give October 58.2°F at dawn and 74.1°F by afternoon, and full-length denim covers that range where shorts do not. White keeps the heat off on the drive back to the coast, and a straight leg sits cleanly over the sandals.
04Hibiscus-red linen midi dress, square neckKahului's October nights average 70.1°F, the last month with a normal low above 70°F until June, so dinner needs one layer of linen and nothing over it until the walk back. A square neck and wide straps keep it on the dinner side of beachwear, and red is the colour this capsule is built around.
05Olive canvas wide-brim hat, chin cordHats head Maui County's list of cover-ups, and on Maui a hat needs a cord: the afternoon trade wind lifts a loose brim off on the first gust along the south-shore path. Heavy canvas holds its shape when it gets wet, the cord and toggle cinch under your chin, and olive matches the shirt.
06Tan woven-leather fisherman sandalsMaui's shore paths cross lava rock as well as sand. A woven cage covers your toes where a slide leaves them bare, the buckled ankle strap holds on a wet step, and leather takes a rinse under the beach shower. They go under the jeans for lunch and under the red midi for dinner.
07Warm-white canvas drawstring bagSand shakes straight out of unlined canvas, and a drawstring closes over a towel, the mineral sunscreen and a phone on the walk back from Kamaʻole. Long straps go over the shoulder with wet hands, and white stays cooler than a dark bag in a parked car at 31.5°C.
08Cherry-red oval sunglassesSunglasses sit on Maui County's cover-up list next to hats and long sleeves, and an October afternoon at 31.5°C puts you on bright water and pale sand for hours. An oval acetate frame covers more of your face than a thin wire one, and cherry red ties the accessories to the dress and the surf suit.
Day to night
Pale olive shirt tucked into white jeans · tan fisherman sandals · olive corded hat · red sunglasses · white drawstring bag. Upcountry before the heat: breakfast in Kula at 58.2°F, lunch in Makawao, the surf suit rolled in the bag for the afternoon.
Hibiscus-red surf suit for a swim at four, then the red linen midi · fisherman sandals · the olive shirt open over it after sunset, about 6:14pm on the 1st and 5:51pm on the 31st. Dinner in Kīhei or Pāʻia at 70°F. From 1 to 4 October, swap the midi for the jeans and the shirt and spend the evening at the Maui County Fair in Wailuku, where a woven toe cage beats an open sandal on a trampled fairground.
A suggested look — pale olive button-down shirt, white slim jeans, tan woven leather sandals, olive canvas bucket hat.

Frequently asked questions
Hot and dry at the coast, mild up the mountain. NOAA NCEI's 1991–2020 normals for Kahului Airport give an average October high of 31.5°C and a low of 70.1°F (21.2°C), with 0.83 inches (21mm) of rain across six or seven days, fewer than two of them with a tenth of an inch or more. Kula, at 3,100 feet, averages 74.1°F by day and 58.2°F at night, and Haleakalā's park headquarters station, at 6,962 feet, 47.8°F at night. The windward side is far wetter: Hāna Airport averages 6.88 inches. Sunset moves from about 6:14pm on 1 October to 5:51pm on the 31st.
A hibiscus-red long-sleeve surf suit, a pale olive long-sleeve shirt, white slim jeans, a hibiscus-red linen midi, an olive canvas hat with a chin cord, tan fisherman sandals, a white canvas drawstring bag and cherry-red sunglasses. That covers a morning Upcountry, an afternoon in the water and a 70°F dinner. Bring mineral sunscreen only: Maui County bans the use of anything else. For a Haleakalā sunrise, add a warm jacket, a hat that covers your ears and closed shoes for those few hours.
Through Recreation.gov. The National Park Service requires a reservation to drive in between 3am and 7am; it costs $1 on top of the $30 vehicle fee, opens 60 days ahead at 7am Hawaiʻi time and often sells out within fifteen minutes, and the park releases a smaller batch two days before each date. Reservations are not refunded for cloud or rain. The summit stands at 10,023 feet, about 30°F colder than the coast, and the park says the hours before dawn are regularly wet, windy and below freezing, with no clothing for sale inside. Wear the white jeans with a warm jacket, a hat and closed shoes; the sun clears the rim at about a quarter past six in mid-October.
Early October, for light and heat. Sunset falls at about 6:14pm on 1 October and 5:51pm on the 31st, and day length drops from 11h 58m to 11h 24m. The first weekend also has the 99th Maui County Fair, Thursday 1 to Sunday 4 October at the War Memorial Special Events Complex in Wailuku, opening with a parade from 4:30 to 6:30pm on the Thursday. Late October sits closer to the change: NOAA's sanctuary puts whale season from November, Pacific Whale Foundation opens its whale-watch season in early November, and NWS Honolulu says larger surf starts reaching north shores by November. If the first whales matter more than the last dry weeks, book the end of the month and run into November.
November is cooler and wetter, and it has whales. NOAA NCEI's Kahului normals give November 85.8°F (30°C) by day and 68.4°F (20°C) at night, against October's 31.5°C and 70.1°F (21°C), and 1.81 inches of rain over about 9 days against October's 0.83 over six or seven. November also brings the first humpbacks, the Southwest Maui Invitational at Lahaina Civic Center from 23 to 25 November, and Thanksgiving on the 26th. October is the month for the water and the Upcountry drive before any of that; our November guide covers the first whale cruises.
Summer clothes with long sleeves over them: linen and cotton on the coast, a rash guard in the water, and a shirt you can button at 58.2°F in Kula. At dinner the aloha shirt is the island's dress shirt. Reyn Spooner, whose name dates to 1961, built its reverse print by combining an inside-out print with the tailoring of an oxford cloth shirt, and for a Hawaiʻi-made print, Sig Zane Designs opened in Hilo in 1985. Manaola's designer, Manaola Yap, learned costume-making from his mother, the kumu hula Nani Lim Yap.
