This Week in Nature: The 3rd week in December - 'opihi

What's Happening in Hawaii 

During the 3rd Week in December: 

Kāpeku ka leo o ke kai,

o ho'oilo ka malama.

When the voice of the sea is harsh, 

the winter months have come.

 December usually brings the year's largest surf, generated by storms in the North Pacific. Kāpeku ("harsh") describes the thunder of big surf and refers to the ancient practice of noisily splashing the water to scare fish into a net. The winter waves have a similar effect, stirring the ocean bottom to depths as great as 240 feet, dislodging a variety of creatures and washing them to shore.

On the islands' northern and western coasts, this is a particularly dangerous time to pick 'opihi (limpets) but a good time to look for sea life on the beaches. In doing so, don't ignore the sand under your feet. The turbulence of storm surf helps create the beaches by bringing ashore the remains of millions of tiny organisms. Much of the white sand of Hawai'i is composed of shells of single-celled animals (Foraminifera, a kind of protozoa), which feed on oceanic bacteria. Some, like the "paper shell" depicted above, grow as large as a quarter of an inch across.

The first snow comes to Mauna Kea about now, though it sometimes happens sooner. Snow may also fall on Mauna Loa and Haleakalā, but it lasts longest on Mauna Kea, whose very name means "white mountain." Poli'ahu, the goddess of snow and sister of Pele, was called  ka wahine kapa hau anu o Mauna Kea, "the woman who wears the cold snow cape of Mauna Kea."

Generally ill-equipped for cold, Hawaiians stayed inside by wood fires when the weather got bitter. Naueue ka hi'u o ka i'a lewa i ke kai, says a proverb about this time of year: "The tails of the fish that move in the sea tremble." Even the fish are shivering.

This Week in Nature - The 1st Week of March - Nana

What's Happening in Hawaii

During the First Week of March (Nana):

The beginning of the hot season is still two months off, but the weather has started to shift. Winter storms and surf are subsiding, and as the Hawaiian writer Kepelino observed, in Nana the leaves on the trees are no longer bruised by hard, driving rains.

A Hawaiian proverb also marks Nana as a month when pāpa'i (crabs) are fat. The nature of this "fatness" is not indicated, but the proverb probably refers to the presence of eggs on the underside of female pāpa'i. This phenomenon, known as berrying, reaches its heaight about this time, prior to heavy spawning that occurs in spring and summer.
