This lists 92°f last month, but it's likely only for this location and not the entire state. It's generally very temperate, with Honolulu averaging 75°-85°f all year. Looks like there are some spots that average a little higher, but the state as a whole has only a single instance of recording 100°f in 1931. But on the other end, the tops of some of the mountains are high enough they get regular snowfall every year, with the lowest ever recorded being 12°f.

ETA -
92°f = 33.3°c

The ocean keeps the temp stable.
