Rain

Rain is a common weather event found in the environments in many titles of The Legend of Zelda series. Typically rain is often found during scenes that are intense or dramatic. In the case of the game Breath of the Wild it is a randomly occurring weather status. Rain also may be summoned by a song like in the games Ocarina of Time and Majora's Mask.

Rain as a Theme
In most instances rain does not affect Link directly and is only present to set the tone of a scene or area. Moments that utilize rain as a tone setter include, but are not limited to, the opening sequence in A Link to the Past, when Midna's Lament is playing in Twilight Princess, and various moments during Wind Waker. Other games may also include rain as ambiance to help define an area.

Rain as a Gameplay Element
In Breath of the Wild rain is randomly generated in warmer areas. It can cause climbing surfaces to become slick, resulting in Link struggling to climb. Rain will put out all fires (with the exception of Ancient Flames) immediately.

In Ocarina of Time and Majora's Mask the "Song of Storms" may be played on the ocarina to summon rain and trigger certain events.
