The weather can make or break a trip to Kalalau. There’s no way to determine the weather months ahead of time when you purchase your permit and plane tickets. If your trip ends up being during a storm, the trail may be closed. If a storm comes while you are at Kalalau, you could be trapped behind a swollen stream. Don’t do something stupid and risk your life to catch a plane. Plan ahead. Make sure you leave plenty of time just in case.
