However, you can express the concept in a few ways:
1. "Ka makani kūpono" This literally means "the suitable wind," but would convey the sense of a favorable wind.
2. "Ka makani ʻoluʻolu" This means "the pleasant wind," and could be used to refer to a wind that is helpful for sailing or travel.
3. "E hoʻomaikaʻi ʻia ʻoe e ka makani" This phrase translates to "May the wind be with you" and is a common blessing for travelers.
It is important to note that Hawaiian is a very nuanced language, and the best way to express "fair wind" would depend on the specific context and your intended meaning.
