Don't forget that Mauna Kea regularly has snow in the winter. Kea is the Hawaiian word for white, mauna is mountain. The top can be white as early as late October, and I could see snow on the peak this year on about May 1. Usually it will melt within a few days of falling, but it can have enough for skiing and sledding.
Here is a view from my house of the mountain with snow well down the sides. You can also spot some of the observatory domes on the summit.
And to illustrate the climate diversity, this is what I see looking the other direction
Beautiful place you have there, CacaoBoy. Do you grow cacao?
