Wind Change

Successful travel by sea or balloon is at the whim of the wind. A ship can't effectively sail against the wind, and a balloon always drifts with it. So what to do if the wind isn't blowing in the direction a magic-user wants it to be? Cast Wind Change. It will change the direction of the wind for a while, thus cutting down travel time significantly. For any frequent traveller who doesn't use Gate Travel, this is an effective tool.

Trivia

 * The Magic Fans in Ultima VI have the same effect.
 * This spell uses the same Words of Power, REL HUR, than Weather from later games. However, Weather is more powerful, affecting not only the wind, but complete storms.
