The Rainbow Warriors, led by third year head coach Gib Arnold, played their home games at the Stan Sheriff Center and were first year members of the Big West Conference.

They lost in the quarterfinals of the Big West tournament to UC Irvine.

The 2012–13 Rainbow Warrior roster was composed of players from eight countries (Angola, Australia, Canada, Croatia, Germany, Latvia, New Zealand, and the United States).

In 2015, Hawaii announced it would vacate wins from this and the 2013–14 season due to the participation of Davis Rozitis and Isaac Fotu, who were ruled ineligible due to improper benefits.

[1] The 2016–17 Hawaii media guide indicates that all but the November 12 win over Houston Baptist were vacated.
