Snow Totals in Hawaii: The Last Storm and the Season So Far

The list near the top of this page reads the National Weather Service's Local Storm Reports for Hawaii from the last 7 days, the biggest first, with the reporter and the time. For your own address, enter a ZIP code in the tool.

At sea level, none: the 1991-2020 normals at Hilo, Honolulu, Haleakala and Lihue are 0 inches. The one snowfall in these records fell at Mauna Loa Observatory, 11,150 feet up.

Mauna Loa Observatory recorded 4.5 inches on December 5, 1958, the biggest single day at the reference stations on this page. The table lists each station’s own.

Enter a ZIP code in the tool. It finds the nearest long record weather station and compares its snowfall since July 1 with the 1991-2020 normal to the same date, and shows last season’s total against a normal season.

Observers measure new snow on a flat board painted white, set out in an open spot away from trees, roofs and drifts, so the snow lands where wind has not rearranged it. The board is read at least every six hours during a storm, because snow settles under its own weight and melts from the bottom. A single reading at the end of a long storm runs low. After each reading the board is swept clean, and the storm total is the sum of the readings. Depth on the ground is a different number: it holds older snow and has settled.
