The Summer Sea is one of the major oceans of the known world. It is located to the south of both Westeros and Essos, separating those continents from the southern landmass of Sothoryos. It is separated from the Narrow Sea by the islands known as the Stepstones, and from the Jade Sea by the Straits of Qarth.
The Summer Islands are located in the Summer Sea, some distance to the south of Westeros. Slaver's Bay and the Gulf of Grief are inlets of the Summer Sea. The largest and most notable cities on the Summer Sea are Volantis and Lys.
In the booksEdit
In the A Song of Ice and Fire novels, the Summer Sea is one of the largest bodies of water in the world, outstripped only by the Sunset Sea lying to the west of Westeros.
