Hilo is the biggest town in Hawaii County, Hawaii. This county covers the entire Island of Hawaii. Hilo is also a special type of community called a census-designated place (CDP).

In 2020, about 44,186 people lived here. Hilo is the fourth-largest town in Hawaii. It is also the biggest town in the state outside of Oahu.

Hilo is the main city for the County of Hawaiʻi. It is located in the South Hilo District. The city sits by Hilo Bay. From Hilo, you can see two huge volcanoes. One is Mauna Loa, which is still active. The other is Mauna Kea, which is a dormant volcano.

Hilo Bay has been hit by giant waves called tsunamis two times. Most people in Hilo live from the bay up the sides of the volcanoes.

Hilo is home to the University of Hawaiʻi at Hilo. It also has the ʻImiloa Astronomy Center. Hilo hosts the Merrie Monarch Festival every year. This festival celebrates ancient and modern hula dancing. It happens after Easter.

You can also find the Mauna Loa Macadamia Nut Corporation here. They are one of the world's top producers of macadamia nuts. Hilo is served by Hilo International Airport.

Hilo's Past: A Journey Through Time

Around the year 1100 AD, the first people arrived in Hilo. They brought their Polynesian knowledge and traditions. We don't have much physical proof from that time. But old stories tell us about people living near the Wailuku and Wailoa rivers. This was during the time of ancient Hawaii. The name Hilo means "to twist" in these old stories.

The name "Hilo" first covered a large area of the east coast of the island of Hawaiʻi. This area is now split into South Hilo and North Hilo. In 1823, a visitor named William Ellis came to Hilo. He noted that the main settlement was Waiākea, on the south side of Hilo Bay. Missionaries came to the area in the early to mid-1800s. They started the Haili Church.

Hilo grew a lot because of sugar plantations nearby. These plantations created many jobs. Workers from Asia came to Hilo to work. For example, by 1887, 26,000 Chinese workers were on Hawaii's sugar cane plantations. The Hilo Sugar Mill was one of them. It produced 3,500 tons of sugar each year back then.

A large wall, called a breakwater, was built across Hilo Bay. It started in the early 1900s and finished in 1929. On April 1, 1946, a very strong earthquake happened near the Aleutian Islands. It caused a giant tsunami that was 14 meters (46 feet) high. This wave hit Hilo 4.9 hours later. It killed 159 people across the islands, with 96 deaths in Hilo alone.

Because of this, an early warning system was created in 1949. It is called the Pacific Tsunami Warning Center. Its job is to track these dangerous waves and give warnings. This tsunami also destroyed the Hawaii Consolidated Railway. Instead, the Hawaii Belt Road was built north of Hilo, using some of the old train tracks.

On May 22, 1960, another tsunami hit Hilo. It was caused by a huge earthquake off the coast of Chile. This wave killed 61 people. Many people did not listen to the warning sirens. Areas near the bay that were once full of homes were turned into parks and memorials.

Hilo started to grow further inland in the 1960s. In the 1980s, downtown Hilo became a cultural hub. Many art galleries and museums opened. The Palace Theater reopened in 1998 as a cinema showing special films.

In the 1990s, the sugar plantations closed down. This hurt the local economy. But in recent years, Hilo has seen new growth in businesses and population.

Hilo's Location and Weather

Hilo is on the eastern side of the island. This is the "windward" side, meaning it gets a lot of wind and rain. The U.S. Census Bureau calls Hilo a census-designated place (CDP). It covers a total area of 151.0 square kilometers (58.3 square miles). Most of this is land, with 12.7 square kilometers (4.9 square miles) being water.

Hilo's Climate: A Rainy Paradise

Hilo has a tropical rainforest climate. This means it gets a lot of rain all year long. Because it's on the windward coast, Hilo is one of the wettest cities in the United States. It gets about 120.39 inches (3058 mm) of rain each year. It rains on about 273 days of the year! The amount of rain changes with how high up you are. Higher parts of Hilo get over 200 inches (5080 mm) of rain annually.

Temperatures are warm all year. The average temperature is about 71.2°F (21.8°C) in February and 76.4°F (24.7°C) in August. The highest temperature ever recorded was 94°F (34°C) in May 1996. The lowest was 53°F (12°C) in February 1962.

Hilo's location on the funnel-shaped Hilo Bay makes it easy for tsunamis to hit.
