Believe it or not, yes. Since snow is pretty basic, you just need some water and cold, and voila! Ok, it's a bit more refined, but on one of my two recent trips to the Big Island of Hawaii, trying to get up to the top of Mauna Kea, the road started to become slushy... something I generally see in the beginning of winter back home in Utah. I rented a Cadillac Escalade, and honestly it was one of the worst in snow. Long story short, it couldn't make it up the hill.
We had to turn around and go back down. I did end up seeing some snow on the road, and about 3" on the sides of saddle road. But I wanted more.
Fortunately, the opportunity came along to see the snow again on a separate trip. A few friends and I went to the top and saw some amazing snow and sunsets. It was a trip well-worth it.
Yes. Sometimes there is snow in Hawaii.
