The sail is likely going to be useless

According to the data from The Alaska Climate Research Center, I am going to kayak against headwind with a probability of more than 50% on the Yukon River. Therefore the sail attached on the kayak is not going to be useful (The wind is likely going to blow from between 10 o'clock and 2 o'clock).

The Alaska Climate Research Centerのデータを調べると、ユーコン川の上で50%以上の確率で向かい風が吹きそうなので、カヤックに帆を張っても役に立ちそうにもない（50%以上の確率で、タッキングしないとすすめない前方120度の範囲から風が吹きそうである）。
