Minecraft wiki entry for Thunderstorm_survival, associated text: If you are a less experienced player, are in ultra hardcore mode where health can't regenerate, or just don't want to risk dying, you probably want to avoid thunderstorms. If you have a bed, Minecraft allows you to sleep through thunderstorms, so you can sleep and when you wake up, the thunderstorm will be gone. However, avoiding thunderstorms are more difficult to avoid safely than they seem if you don't have a bed to sleep through it.
