"The trip is in the fall."
Translation:Aia ka huakaʻi i ke kau hāʻulelau.
Not sure when this word came into being, but it seems when whoever decided they needed a word for autumn (not to describe anything happening in Hawai'i) they made it literal / understandable to everyone... Like spring (I'd say there's no spring here either?) - wehewehe actually says "Season. No Hawaiian word; terms sometimes used: kupulau..." (and "kupu" is "nvi. Sprout, growth", so again, descriptive).
