Weatheria is an island floating in the sky. It appears to be floating on top of a large bubble, and it is notable for the study of weather conditions as well as tools that can create various conditions, such as the Wind Knot. The only resident whose name is known is Haredas. Nami was sent here by Bartholomew Kuma during the events of Sabaody Archipelago, and spent two years on the island honing her skills.
