Yes, the North Sea borders Great Britain to the east—but "surrounds" is geographically imprecise. Great Britain is an island; it's surrounded by water on all sides. The North Sea is just one of several bodies of water doing the surrounding.
| Direction | Water Body | Connection |
|---|---|---|
| East | North Sea | Strait of Dover → English Channel |
| South | English Channel | Strait of Dover → North Sea |
| West | Irish Sea | North Channel → Atlantic |
| Northwest | Atlantic Ocean (direct) | — |
| North | Atlantic Ocean (via Norwegian Sea) | — |
Great Britain's maritime climate comes from all surrounding waters: Gulf Stream via Atlantic (west), North Sea moderation (east), Channel mixing (south). No single sea "surrounds" it—the ensemble does.
So: North Sea = eastern neighbor. "Surrounds" = Atlantic + North Sea + Channel + Irish Sea together.
