The average household size was 3.17, and the average family size was 3.99. As of 2010, in the CDP the population was spread out, with 27.8% under the age of 18, 8.5% from 18 to 24, 24.3% from 25 to 44, 25.7% from 45 to 64, and 13.5% who were 65 years of age or older. The median age

235-578: A refuge decreased in size. More than 250 species of local flora are federally listed as endangered or threatened. Birds found on other islands as well as Maui include the I'iwi ( Drepanis coccinea ], 'Apapane ( Himatione sanguinea ), Hawai'i 'Amakihi ( Chlorodrepanis virens), as Maui 'Alauahio ( Paroreomyza montana ) well as the Nene ( Branta sandvicensis , Hawaii's state bird), Hawaiian coot ( Fulica alai ), Hawaiian stilt ( Himantopus mexicanus knudseni ). In 2024, Haleakalā National Park began to employ

282-714: A single island. Maui is one such "volcanic doublet," formed from two shield volcanoes that overlapped to form Maui. The older, western volcano has eroded considerably, forming the peaks of the West Maui Mountains (in Hawaiian, Mauna Kahalawai). Puʻu Kukui is the highest, at 5,788 ft (1,764 m). The larger, younger volcano to the east, Haleakalā , rises to 10,023 ft (3,055 m) above sea level, and measures 5 mi (8 km) from seafloor to summit. The eastern flanks of both volcanoes are cut by deeply incised valleys and steep-sided ravines that run downslope to

329-575: A species of moa-nalo (also found on Molokaʻi, Lānaʻi, and Kahoʻolawe), a species of harrier (the wood harrier , shared with Molokaʻi), an undescribed sea eagle (Maui only), and three species of ground-dwelling flightless ibis ( Apteribis sp. ), plus other species. Today, Maui's most notable surviving endemic birds are probably the 'Akohekohe ( Palmeria dolei ) and the Maui parrotbill ( Pseudonestor xanthophrys ), also known as Kiwikiu , both of which are critically endangered and only found in an alpine forest on

376-494: A worker. Fagel spent four months in jail while the strike continued. Eventually, Vibora Luviminda made its point and the workers won a 15% increase in wages after 85 days on strike, but no written contract was signed. Maui was involved in the Pacific Theater of World War II as a staging center, training base, and rest and relaxation site. At the peak in 1943–1944, more than 100,000 soldiers were based there. The main base of

423-455: Is dominated by two volcanic features: Haleakalā in the southeast, and the West Maui Mountains in the northwest. The two are connected by an isthmus about six miles wide that gives the island its nickname, the Valley Isle. Maui has a significant tourism industry, with nearly three million visitors in 2022. A 2023 report based on 2017 data concluded that nearly 40% of Maui County's economy

470-457: Is open 24/7 for urgent care and emergency access. The facility also offers routine physical exams, acute care, chronic disease management (heart disease, diabetes, asthma), cancer screening (Pap smears, mammograms, prostate and colon), routine gynecology, family planning services, basic laboratory and x-ray, on-site medication dispensary, and referrals for specialty care. Major employers in Hana include

564-505: The 4th Marine Division was in Haiku . Beaches were used to practice landings and train in marine demolition and sabotage. In early August 2023, a series of wildfires broke out in the U.S. state of Hawaii , predominantly on the island of Maui. The wind-driven fires prompted evacuations and caused widespread damage, killing at least 102 people and leaving two people missing in the town of Lahaina on Maui's northwest coast. The proliferation of

611-484: The Haleakalā National Park . Hana's climate is hot and wet year round, typical of a tropical rainforest . As of the census of 2010, Hana had 1,235 residents, 390 households, and 252 families residing in the CDP. The 2010 population density was 105.6 people per square mile (40.8 people per square kilometer). There were 506 housing units at an average density of 48.2/sq mi. The racial makeup of

658-637: The 19th century. Hana, Hawaii Hana ( Hawaiian : Hāna ) is a census-designated place (CDP) in Maui County, Hawaii , United States. The population was 1,526 at the 2020 census . Hana is located at the eastern end of the island of Maui and is one of the most isolated communities in the state. It is reached mainly via the Hana Highway , a long, winding, 52-mile-long (84 km) highway along Maui's northern shore, via boat, and with commercial air service to Hana Airport . Like most of Hawaii, Hana

705-610: The 2000s, controversies raged over whether to allow continued real-estate development. Vacation rentals in residential neighborhoods became a flashpoint - many were unpermitted, and were later closed after enforcement escalated. The Hawaii Superferry briefly offered interisland service, before it was banned for not having completed an EIS . In 2016, Maui residents convinced officials to switch to organic pesticides for highway applications after they learned that label requirements for glyphosate formulations had not been followed. The new millenium brought droughts, increasing pressure on

752-444: The 30-year period of 1978 to 2007. If the islands of Hawaii did not exist, the average annual rainfall on the same patch of water would be about 25 in (640 mm). Instead, the mountainous topography induces an average of about 70 in (1,800 mm). In the lowlands, rainfall is most likely to occur during night or morning hours, and least likely in mid-afternoon. The most pronounced daily variations in rainfall occur during

799-434: The CDP was 22.2% White , 0.1% African American , 0.1% American Indian and Alaska Native , 5.0% Asian , 29.1% Pacific Islander , 0.8% from some other race , and 42.8% from two or more races. Hispanic or Latino of any race were 9.8% of the population.

846-604: The East rift zone of East Maui Volcano (Haleakalā). The Hana Airport offers flights with regular service to the Big Island , Kahului , and Oʻahu . According to the United States Census Bureau , this CDP has a total area of 11.7 square miles (30.3 km ), of which 10.5 square miles (27.3 km ) is land and 1.2 square miles (3.0 km ), 9.77%, is water. Near Hana are natural areas and several swimming holes in

893-730: The Harvard Observatory was installed in 1949, a 6-inch (15 cm) prominence camera, and a flare patrol camera, installed in the Grain Bin Dome. These instruments were followed by the Evans Solar Facility, or Big Dome, which housed a 16-inch (41 cm) coronograph and spectrograph. In 1963 the Hilltop Dome was built to house additional instruments. The Sacramento Peak facilities are located in Sunspot, New Mexico . The site's name

940-677: The Hotel Travaasa – Hana and today as the Hyatt Hana-Maui Resort, which helped transition the economy towards tourism. The winding, famously scenic Hana Highway was completed in 1926. Originally paved with gravel, it provided the first land vehicle access to the town. Hana's population peaked in the first half of the twentieth century, with a population of about 3,500. Hana is located at 20°46′12″N 155°59′39″W  /  20.77000°N 155.99417°W  / 20.77000; -155.99417 (20.770017, −155.994179), directly on

1034-454: The concentration of endemic species found in some other Hawaiian islands. As recently as 200,000 years ago Maui was part of Maui Nui, thus reducing the odds that birds or other species would be endemic to any single one of these. Although Molokaʻi had several endemic bird species, in modern times Maui Nui's other islands host little endemic birdlife. During and after the Maui Nui period, Maui hosted

1081-401: The core of Hawaiian culture. Modern Hawaiian history began in the mid-18th century. Kamehameha I , king Hawaiʻi island , invaded Maui in 1790 and fought the inconclusive Battle of Kepaniwai . He returned to Hawaiʻi to battle a rival, subduing Maui a few years later. On November 26, 1778, explorer James Cook became the first European to see Maui. Cook never set foot on the island, because he

1128-509: The eclipse path, to produce 90 continuous minutes of images, 10 seconds apart, of the Sun's inner corona . This was to provide a clearer understanding of solar plumes and other transient phenomena. Maui Maui ( / ˈ m aʊ i / ; Hawaiian : [ˈmɐwwi] ) is the second largest island in the Hawaiian archipelago , at 727.2 square miles (1,883 km ). It is the 17th-largest in

1175-620: The end of the 19th century as petroleum replaced whale oil . Along with the rest of Hawaii, Maui was part of the Hawaiian Kingdom , the Republic of Hawaii , Hawaiian territory , and the state of Hawaii . In 1937, Vibora Luviminda trade union conducted the final ethnic strike action in the Hawaiian Islands against four Maui sugarcane plantations , demanding higher wages and the dismissal of five foremen. Manuel Fagel and nine other strike leaders were arrested, and charged with kidnapping

1222-549: The first school in Lahaina, Lahainaluna Mission School, which opened in 1831 and still exists. At the height of the whaling era (1843–1860), Lahaina was a major center. In one season over 400 ships visited with up to 100 anchored at one time in Lāhainā Roads . Ships tended to stay for weeks rather than days, fostering extended drinking and the rise of prostitution , against which the missionaries battled. Whaling declined steeply at

1269-522: The founding of the observatory is given below. The Sacramento Peak observatories were proposed by Donald Menzel of the Harvard College Observatory in 1947, when the U.S. Air Force commissioned a site survey for a suitable facility that would study the higher regions of the Earth's atmosphere. The site, near White Sands Proving Ground , was chosen in 1948. The first equipment to be operated by

1316-414: The incompatible insect technique to reduce the park's mosquito population. Maui is also home to the Hawaiian hoary bat , Hawaii's only native terrestrial mammal. Marine mammals notably include spinner , bottlenose , and spotted dolphins . Polynesians from Tahiti were Maui's original inhabitants. They introduced the kapu system, a strict social order that affected all aspects of life and became

1363-536: The island after his son, who in turn was named for the demigod Māui . Maui's previous name was ʻIhikapalaumaewa. Maui Island is also called the "Valley Isle" for the large isthmus connecting its northwestern and southeastern volcanic masses. The islands' volcanic cones are formed from basalt , a dark, iron -rich/ silica -poor rock, which poured out of thousands of vents as fluid lava over millions of years. Some of its volcanoes were close enough to each other that lava flows on their flanks overlapped, merging into

1410-592: The leeward coasts and at the highest elevations), and dominant trade wind flow (especially at lower elevations). Maui has a range of climatic conditions and weather patterns: Maui displays diverse climatic conditions, each of which is specific to a sub-region. These sub-regions are defined by major physiographic features (such as mountains and valleys) and by location on the windward or leeward side. Maui's daytime temperatures average between 75 °F (24 °C) and 90 °F (32 °C) year round, while evening temperatures are about 15 °F (8.3 °C) cooler in

1504-513: The more humid windward areas, about 18 °F (10 °C) cooler in the drier leeward areas, and cooler still in higher elevations. An exception to the normal pattern is the occasional winter Kona storm that brings rainfall to the South and West areas accompanied by high southwesterly winds (opposite of the prevailing trade wind direction). Maui has examples of all microclimates, each typical to specific locations. These microclimates help to define

1551-442: The natives, banned hula , and greatly altered the culture. The missionaries taught reading and writing, devised the Hawaiian alphabet , operated a printing press in Lahaina, and began recording the islands' history, which had been transmitted only orally. The missionaries both altered and preserved the native culture. The religious work altered the culture while the literacy efforts preserved history and language. Missionaries started

1598-456: The now submerged Penguin Bank . During periods of reduced sea level, including as recently as 200,000 years ago, the channels between them become exposed and join the island into a single landmass. The climate is characterized by a two-season year, tropical and uniform temperatures at any given elevation, geographic differences in rainfall, high relative humidity, extensive cloud formations (except on

1645-536: The poverty line, including 10.4% of those under age 18 and 3.8% of those age 65 or over. Hana's surfing culture was profiled by writer Susan Orlean in Outside magazine in 1998, inspiring the 2002 film Blue Crush . Although not technically a hospital or emergency room, Hana Health Clinic (or Hana Medical Center), works in cooperation with American Medical Response and Maui Memorial Medical Center to stabilize and transport patients with emergent medical conditions. It

1692-498: The rocky, windswept shoreline. The isthmus was formed by sandy erosional deposits. Maui's last eruption (originating in Haleakalā's Southwest Rift Zone) likely occurred between 1480 and 1600; the resulting lava flows are located at Cape Kīnaʻu between ʻĀhihi Bay and La Perouse Bay . Haleakalā is dormant, but not extinct. Maui is part of a much larger unit, Maui Nui , that includes the islands of Lānaʻi , Kahoʻolawe , Molokaʻi , and

1739-533: The summer because summer rainfall generally consists of night-time trade wind showers. Winter rainfall in the lowlands is the result of storm activity, which is as likely to occur in the daytime as at night. Rainfall variability is far greater during the winter when occasional storms contribute appreciably to rainfall totals. Such wide swings in rainfall produce occasional droughts, sometimes causing economic losses. These occur when winter rains fail to produce sufficient significant rain, impacting normally dry areas outside

1786-496: The trade winds that depend on them the most. The winter of 2011–2012 produced extreme drought on the leeward sides Maui, and some other islands. Maui is home to a large rainforest on the northeastern flanks of Haleakalā, which serves as the drainage basin for that side. Maui is home to many coral reefs . However, many have been damaged by pollution, run-off, and tourism, although sea turtles, dolphins, and Hawaii's celebrated tropical fish remain abundant. Leeward Maui once boasted

1833-551: The warm waters. They are typically sighted in pods: small groups of several adults, or groups of a mother, her calf, and a few suitors. Humpbacks are an endangered species protected by U.S. federal and Hawaiʻi state law. An estimated 21,000-26,000 humpbacks live in North Pacific waters. Although they face many dangers, due to pollution, commercial vessels, and military sonar testing, their numbers have increased rapidly in recent years, estimated at 7% growth per year. Birdlife lacks

1880-473: The wildfires was attributed to dry, gusty conditions created by a strong high-pressure area north of Hawaii and Hurricane Dora to the south. The island experienced rapid population growth through 2007. At the time, Kīhei was one of the most rapidly growing towns in the United States. The island attracted many retirees, with accompanying service providers. Population growth produced strains, including traffic, housing cost/availability, and access to water. In

1927-472: The windward slopes of Haleakalā. Conservation efforts have examined how to mitigate female parrotbill mortality since that is s a key driving factor driving population decline. The parrotbill lacks resistance to mosquito-born diseases, particularly avian malaria , so only forests above 1500 meters of elevation provide refuge. The habitat was undergoing restoration in east Maui as of 2018. As Maui's human population grew, previously undeveloped areas that provided

1974-412: The ʻĪao aquifer , with withdrawals rising above 18 million U.S. gallons (68,000 m ) per day. Recent estimates indicate that Maui has a potential supply of potable water around 476 million U.S. gallons (1,800,000 m ) per day, virtually all of which drains into the ocean. Water for agriculture comes mostly from East Maui streams, routed through a network of tunnels and ditches dug by Chinese laborers in

2021-418: Was 35.2 years. For every 100 females, there were 105.5 males. For every 100 females age 18 and over, there were 111.9 males. As of 2000, the median income for a household in the CDP was $ 50,833, and the median income for a family was $ 54,167. Males had a median income of $ 26,146 versus $ 22,969 for females. The per capita income for the CDP was $ 14,672. About 5.6% of families and 8.6% of the population were below

Sadler , (1920–2005), an internationally noted meteorologist and professor at The University of Hawaii , formerly with the United States Air Force on assignment during the early inception of the observatory. For the Solar eclipse of August 21, 2017 , NSO enlisted the cooperation of various groups in the Citizen CATE (Continental-America Telescopic Eclipse) experiment to set up more than 60 identical telescopes along

2115-479: Was probably first settled between 500 and 800 AD by Polynesian peoples . The first sugarcane plantation in the area was established by George Wilfong in 1849, and by 1883 there were six plantations operating in the area. By 1946, however, the last sugarcane plantation had closed, leading plantation workers to move mostly to the west side of Maui. That same year saw the opening of the Kaʻuiki Inn, later known as

2162-487: Was tourism-related. Popular tourist destinations include the resorts in the Kāʻanapali, Kapalua, and Kihei/Wailea/Makena areas; Hāna and the Hana Highway ; Iao Valley ; Haleakalā National Park ; and its many beaches. Native Hawaiian tradition gives the origin of the island's name in the legend of Hawaiʻiloa , the navigator credited with discovering the Hawaiian Islands . According to that tradition, Hawaiʻiloa named

The first European to come ashore was French admiral Jean-François de Galaup, comte de Lapérouse , who landed on the shores of what became La Perouse Bay on May 29, 1786. More Europeans followed: traders, whalers, loggers (e.g., of sandalwood ) and missionaries . The latter began to arrive from New England in 1823, settling in Lahaina, at that time Hawaii's capitol. They clothed
